The basics of apa.

We’re going to start from the beginning for all of you newbies out there, or for those of you looking for a refresher.

APA is an abbreviation which stands for American Psychological Association. This is a massive organization, responsible for creating and sharing psychology-related publications, research, and databases.

Basically, they keep psychologists and other similar roles in the loop with what’s happening in the world of psychology. With close to 120,000 members, this is THE leading world organization related to psychology.They are not officially associated with this guide, but the information here talks about their citing format and rules in depth.

Why were APA citations created and why did my teacher ask me to use this style?

Are you scratching your head, wondering what is APA style is and how this all relates to your research project? To make a long story short, the American Psychological Association did something really cool. Back in 1952, they created a way for ALL psychology researchers to structure their citations. This standard method did three things:

• Psychology researchers were all able to display the sources they used in a systematic way.
• Readers were able to easily understand the information shown in citations.
• There was enough information displayed in the citations for readers to go out and find the exact sources on their own.

APA citations were such a hit, they were so good, that other science disciplines soon adopted the citation format as well. In fact, other disciplines outside of the science world use APA style today, too. So, whether you’re creating a psychology-related research project or not, there’s a good chance you were asked to create your citations in APA style.

Currently in its 7th edition, the Publication Manual of the American Psychological Association is one of the most frequently used style guides for academic writing today!

With the 7th edition just coming onto the scene in 2020, the American Psychological Association does not expect to see widespread usage of the 7th edition until later in 2020. This is why you should always double-check with your teacher on whether they want you to use the 6th edition or the 7th edition for your projects.

Click here for more basics on this style.

Another widely used style is MLA format . Believe it or not, there are thousands of other styles, so perhaps your teacher or professor requested a completely different one. If you’re in that boat, head to EasyBib.com to check out more styles . While you’re at it, poke around and check out our APA reference generator. It may be just what you’re looking for.

References vs. Citations – What’s the difference?

References and citations are two terms that are thrown around a lot and quite often mean the same thing. A reference, or citation, shows the reader that a piece of information originated elsewhere. But, along came APA and decided to throw a curveball at us. In APA, the two terms have two different meanings.

A citation is found in the actual writing of an APA research paper.

In-text citation example:

“Lecture-rooms are numerous and large, but the number of young people who genuinely thirst after truth and justice is small” (Einstein, 2007, p. 5).

A reference is found on the reference page, which is the last page of a research paper. 

Reference Page Example:

Einstein, A. (2007). The world as I see it. Google Books. https://books.google.com/books?id=aNKOo94tO6cC&source=gbs_navlinks_s (Original work published 1934)

The information included in an APA citation is just a snapshot of the information found in the full reference. For more information on when it’s appropriate to include a citation in your paper, head to section 8.1-8.10 of the Publication manual.

Now, what makes things even trickier is that most teachers and professors use the term “APA citations” when they’re actually talking about the full references. How many times have you heard your teacher say, “Make sure you have your citations on the last page!”

Eek! So, to stay on the same page as your teacher, this guide shows you how to make references for an APA reference page, but we’re calling the page “APA Citations.” Someone’s gotta give in, right? Looks like it’s us.

If you’re looking for a quick read on the citations found in the body of the paper, check out our APA Parenthetical Citation page. It’s just one of the many free APA citation guides available on EasyBib.com. Need an APA citation generator? You can find one at EasyBib.com as well!

A rundown on references

Before we get into the nitty-gritty details on how to structure references for your APA paper, let’s get one more quick piece of information off the table.

References are added to research papers and projects only when a source is included in the writing itself.

We don’t add references to a reference page if we want to simply suggest other, similar titles. No! We create references when an actual piece of information from another source is added into the project.

Does your paper include a piece of data from a report? Great! You copied a line of text from a case study and put it in your project (with quotation marks around it)? Perfect! You included a bar graph you found in a brochure? Fantastic! Make sure you create an APA citation in the text of your paper and include the reference on the final page.

The only exception to the above rule is if you’re creating an “annotated bibliography.” For more on that, check out our APA annotated bibliography page.

In case you were wondering, the same goes for MLA in-text & parenthetical citations on the MLA works cited page.

Ready to get started? The next section of the guide is going to explain, step-by-step, how to structure every nook and cranny of your references.

But, if you’re dreaming of an APA citation maker to help make the pain go away from building your references from scratch, you’re in luck. EasyBib.com has an APA citation maker!

Fundamentals of an APA citation

This entire section goes into detail on each component of a reference. If you’re looking to learn how to style the names of the authors, the title, publishing information, and other aspects related to the reference, this section is for you!

If you want to skip the small talk and see an APA style paper example, go to the “Citation Resources” menu on this page and select “APA Format Guide.” It includes a title page example, an APA paper example, and an APA reference page example.It’s all there for you and the best part about it is it’s free! Do yourself a favor and take a peek at it now!

Author information

The very first piece of information in most references is the author’s name(s). We say “most,” because some sources may not have an author (such as websites, the Bible…). If your source doesn’t have an author, do not include any information about an author in your reference.

Citing a Source with 1 Author

Apa structure:.

Last name of the Author, First initial. Middle initial.

APA Example:

To see some examples, scroll down to the bottom half of this page.

Citing a Source with 2 Authors

Does your source have two authors? Do not put the names in alphabetical order. They should be written in the order they’re displayed on the source.

Last name of the 1st listed Author, First Initial. Middle Initial., & Last name of the 2nd listed Author, First initial. Middle initial.

Doe, J. B. & Chen, W. I.

For an example of a reference with two authors according to the 7th edition of the Publication manual , scroll down to the “Journal Articles found in Print” section, or check out section 9.7-9.12 in the Publication manual.

Citing a Source with 3 to 20 Authors

Does your source have three to twenty authors? The American Psychological Association has made some updates on how to list multiple authors in your citations. If you have between three to twenty authors, list all the authors names (Last Name, Initials). Put them in the same order they’re listed in the source. Commas separate names, and put an ampersand right before the last name.

Bos, G., Hajek, S., Kogman-Appel, K., & Mensching, G. (2019). A Glossary of Latin and Italo-Romance Medico-Botanical Terms in Hebrew Characters on an Illustrated Manuscript Page (Ms. Oxford, Bodleian Opp. 688, fol. 177b). Aleph: Historical Studies in Science and Judaism 19 (2), 169-199. https://www.muse.jhu.edu/article/747571

Citing a Source with 21+ Authors

If your source has over twenty authors, list the last name and initials of the first 19 authors, placing a comma between each name. After the name of the 19th author, use an ellipsis in place of the remaining authors’ names. Then, list the final author’s name in front of it.

Here’s a formatting example for 21+ names using the U.S. presidents (this is NOT a reference example):

Washington, G., Adams, J., Jefferson, T., Madison, J., Monroe, J., Adams, J. Q., Jackson, A., Van Buren, M., Harrison, W. H., Tyler, J., Polk, J., Taylor, Z., Fillmore, M., Pierce, F., Buchanan, J., Lincoln, A., Johnson, A., Grant, U. S., Hayes, R. B., … Trump, D. J.

Citing an Author that is an organization or company

If your source is written by an organization or company:

Some sources are written and released by companies, not necessarily individual people. For example, most brochures at museums only display the institution’s name. Advertisements also only show the company’s name. If the source you’re attempting to cite only shows a group or organization’s name, place it in the reference in the place you’d normally include an individual person’s name.

Write out the name of the group in full; do not use abbreviations. For example, it may seem okay to use USDA, but APA writing style prefers you write out United States Department of Agriculture.

If you’re looking for information on how to style your own name in APA headings, find the example paper on EasyBib.com.

Formatting Titles & Dates

Formatting the date of publication.

The date the source was published is the next item shown in a reference. It’s directly after the author’s name.

For the majority of sources, include only the year in parentheses.

If you’re citing an article in a magazine, include the year and the month.

Peterzell, J. (1990, April). Better late than never. Time, 135 (17), 20–21.

Check out the examples towards the bottom of the page, or head to sections 9.13-9.17 of the Publication manual to see how dates are displayed.

Title rules and capitalization

Titles are the next piece of information shown in a reference. Titles are often tricky for people to style. Students often wonder, “Should I type out the title as it’s shown on the source?” “Should the title be written in italics or underlined?” Here are the answers to (hopefully) all of your title-related questions:

Which letters are capitalized?

Most titles are written with a capital letter in these places:

• At the beginning of the title
• At the beginning of a proper noun
• At the beginning of the subtitle

It may be tempting to write the title as you see it shown on the source, or with capital letters at the beginning of every important word, but that’s not how APA referencing does it.

Here are a few examples of proper lettering:

• A star is born
• Spider-Man: Into the spiderverse
• Harry Potter and the deathly hallows

The only source types that are written with a capital letter at the beginning of every important word are periodicals. Some examples include the titles of newspapers, journals, and magazines.

• The New York Times
• School Library Journal,

How should I style the title?

• Anything that stands alone is written in italics. When we say “stands alone,” we mean it isn’t part of a larger collection. Most books are a single source, so they’re written in italics. Other examples include movies, brochures, dissertations, and music albums.
• Sources that are part of a collection are written without italics. Website pages, journal articles, chapters in books, and individual songs (from an album) are written without italics.
• Remember, the styling information above is for the APA reference page only! Citations in the text of the paper are styled differently. If you need to see a full APA sample paper, check out the other resources on EasyBib.com!

Check out some of the examples below to see how the titles are typed out and styled. You can also head to section 9.18-9.22 of the Publication Manual for more details

If it’s not the actual title, but an APA title page for your paper that you need help with, check out the Title Page APA creator on the homepage of EasyBib.com! Or, check out the main guide for this style, which includes an APA cover page template.

Additional information about a source

It can be difficult to understand a source type just by looking at an APA style citation. Sometimes it isn’t clear if you’re looking at a citation for a presentation, a blog post, lecture notes, or a completely different source type.

To clear up any confusion for your reader, you can include additional information directly after the title. This additional information about the source type is written in brackets with the first word having a capital letter.

Wilson, T. V. & Frey, H. (2019, May 13). Godzilla: The start of his story [Audio podcast]. iHeart Radio. https://www.missedinhistory.com/podcasts/godzilla-the-start-of-his-story.htm

Thanks to the information in the brackets, the reader can easily see that the source is an audio podcast.

Check out the various examples towards the bottom of this page.

Publication information

Publication information includes the name of the publisher. In most cases, the publication information is only included for print sources. Check out the book reference below to see the publication information in action.

Citing a chapter in an edited book in print in APA

An edited book is one that was compiled by an author. Each individual chapter, or section, is written by someone else. Since you’re probably citing the specific chapter, rather than the whole entire book, place the name of the chapter’s author in the first position.

Citing The Bible in APA

Since the bible is considered a “classical work,” and widely known, it is not necessary to create a full reference. Only include a citation in the text of the paper.

Two items need to be included:

• The title and version of the source, such as the New Living Bible
• The names, verses, chapters, or any numbers associated with the section you’re referring to.

“Then the king asked her, “What do you want, Esther? What is your request? I will give it to you, even if it’s half the kingdom” (Esther 5:5 New Living Translation).

Citing a Source on the Internet in APA

Citing digital sources in this style is much easier than other styles. If you’re wondering why, it’s because a lot of information isn’t included in the reference.

For most digital sources, only five items are usually needed:

• The name of the author
• The date the source was published
• The title of the source
• The medium (blog post, audio file, pdf, etc.)
• The website address

Here’s some more information related to web content:

• Only include the medium if it’s unique or if it will help the reader understand the source type.
• Include the website address at the end of the citation.
• Do not place a period at the end of the website address.

Have a digital source? Need to cite APA? Check out some of the examples below.

Citing online encyclopedias & dictionaries – Group author

If you conducted or watched a personal interview and the transcript or audio is not available for the reader, then there really isn’t any point to create a full reference. These types of sources are not recoverable and the reader would be unable to find the interview on their own. Instead, only create a citation in the text of the paper. Use the first initial, middle initial, and last name of the person being interviewed, along with “personal communication,” and the date of the interview.

Institution or organization name. (n.d.). Entry title. In Title of Website or reference . Retrieved Month Day, Year, from URL

Merriam-Webster. (n.d.). Doleful. In Merriam-Webster.com dictionary. Retrieved March 1, 2020, from https://www.merriam-webster.com/dictionary/doleful

Citing online encyclopedias & dictionaries – Known author

If there is a known author, cite the source this way:

Last name, F. M. (Date published). Entry title. In F. M. Last name (ed.), In Title of Website or reference . Retrieved Month Day, Year, from URL

Mann, M. E. & Selin, H. (n.d.). Global warming. In Encyclopaedia Britannica . Retrieved March 1, 2020, from https://www.britannica.com/science/global-warming

Citing Wikipedia

Cite a Wikipedia page just like a normal webpage, but use an archived version. Go to the “View history” tab at the top of a Wikipedia page to find these archived versions, their publishing date, and their URL.

Citing Media Sources in APA

Citing a song or music listened to online in apa.

Note: include a URL in the reference if that location is the only means of retrieval (like if they only post their music to SoundCloud or on their own specific website). If the song is available across multiple platforms, no URL is needed.

APA Structure for a modern song:

Artist’s Last Name, F. M. (Year published). Song’s title [Song].  On Title of album . Publisher(s).

Grande, A. (2019). 7 rings [Song]. On thank u, next . Republic Records.

Dictionary entry from an online source

• Use “n.d” if the date is not listed.
• Write the name of the dictionary in italics and follow it with a period.
• Write “Retrieved” then the date you accessed the entry online in this format: Month Day, Year. End it with a comma.
• Write “from” and add the page URL.

Solution #3: How to ensure that an auto-generated citation in APA style is correct

• Ensure that the correct number of people are accredited by counting the names in the source and the website citation.
• Ensure that all names are spelled correctly.
• If 2-20 authors are used, ensure that an ampersand is used before the last name.
• If more than twenty authors are used, ensure that an ellipsis is used before the final author.
• Check to make sure that the date is correct and that the month or year do not need to be adjusted.
• Generally, works cited as a whole, such as books, are written in italics, while shorter works that are part of a bigger work, such as a chapter in a book or articles from a periodical (e.g., journal, magazine, newspaper, etc.), are usually in regular font.
• The title of webpages are italicized, while the title of the site they are on is in regular font.
• Social media post citations use the written post content (up to 20 words) as the title. This “title” should be italicized.
• If using a chapter, make sure that the editor is accredited.
• If using an article, make sure that the journal number is italicized and that the volume number is in parentheses.
• Make sure that your links are active and that they bring you to the correct location. You may need to rewrite the link.

Helpful Tip!

How do I cite an article I found using an iPhone, Android, or computer-based app? It doesn't matter on what device you read the article, but providing the reader a direct path to the " original " source of the material.

Remember - the "app" is not the source of the article - the "journal" is your source. Cite it as you would any journal article.

Digital Object Identifier (DOI)

What is a DOI? A DOI ( digital object identifier ) is a unique alphanumeric string assigned by a registration agency (the International DOI Foundation) to identify content and provide a persistent link to its location on the internet. 

NOTE: It is regarded as the most important part of the citation because it will accurately direct users to the specific article.

Think of it as a "digital fingerprint" or an article's DNA!

The rules for DOIs have been updated in the 7th edition of the Publication Manual of the American Psychological Association. They should be included as URLs, rather than just the alphanumeric string.

Correct:  

• http://doi.org/10.1186/1471-2288-12-114
• http://dx.doi.org/10.1186/1471-2288-12-114

Incorrect:     

• doi: 10.1186/1471-2288-12-114
• Retrieved from http://doi:10.1186/1471-2288-12-114

Getting Started!

American Psychological Association (APA) style is commonly used for citing references in student papers in science, medical, public health, health sciences and nursing as well as the social science.

 The purpose of documentation is to:

• Identify ( cite ) other people’s ideas and information used within your essay or term paper.
• Indicate the authors or sources of these in a References list at the end of your paper.

This guide is based on the APA Manual (7th ed.) that was published in 2020. 

The following sections provide you with information and examples that will help you to cite the sources that you come across during your research. 

Journal/Magazine Articles

Audiovisual Media

Figures/Images

Other Sources

APA Citation Guidelines (7th Edition): Style & Format

About this Page

This page contains information on the style and format of papers according to APA 7th edition using the Concise Guide to APA Style: The Official APA Style for Students .

• APA Style and Grammar Guidelines

APA Style papers should have the same style and size of font throughout the text of the paper (title page to reference page). APA considers the following fonts acceptable: 11- point Calibri, 11-point Arial, 10-point Lucida Sans Unicode, 12-point Times New Roman, 11-point Georgia, or 10-point Computer Modern. It is recommended that you check with your instructor to see if they have a preferred font style.

(See section 1.18 of the Concise Guide to APA Style )

The first line of every paragraph in the text of your paper and every reference on your reference page is indented (hit the tab key once). The remaining lines are left flush with the left-hand margin of the paper (this is known as a "hanging indent").

Other Format Guidelines

Page numbers : Title page through reference pages are numbered using Arabic numerals;  place each number in the top right corner of the page.

Running heads: Are NOT required in student papers, but you should still check with your instructor to see if they wish them to be used.

Dashes: APA uses em dashes (long dash) and en dashes (short dash). See section 4.6 of the Concise Guide to APA Style for more information.

Lines and Margins

APA Style papers should have double-spaced text throughout the entire paper (including quotations and references). To make your paper double-spaced in Microsoft Word, highlight the text you want double-spaced, and then click Layout . Next, click on the arrow to the right of the word Paragraph (a pop-up appears). From the drop-down menu under Line Spacing , select Double (default choice is Multiple ) and click OK .

APA Style papers use 1 inch margins all around (top to bottom and left to right). Margins in Microsoft Word are set to 1 inch by default. If you are unsure, you can check your margins by clicking Layout, and clicking Margins. Once the drop-down menu appears, make sure Normal is selected to ensure you have 1 inch margins all around your paper.

(See sections 1.20 and 1.21 of the Concise Guide to APA Style )

APA Style recommends ONE space after a period when the period ends a sentence, separates parts of a reference list entry, or follows initials in names (J.B. Jones).

Do NOT put a space after a period when the period is part of an internal abbreviations (U.S. or a.m.)

Do NOT use periods for the abbreviation of state, province, or territory names (AZ; KS; BC); capital letter abbreviations and acronyms (APA, AMA, EPA); for abbreviations of academic degrees (PhD, MD, DO); or for abbreviations of metric and nonmetric measurements (cm, hr, kg,). Note: Use a period when abbreviating "inch" or "inches" (in.) or else it could be misread.

(See sections 4.1 and 4.2 of the Concise Guide to APA Style )

Sentence Case vs. Title Case

Sentence case is where most words in a sentence are going to be lower case.

The EXCEPTIONS are the first word in a title, heading, or sub-title ; proper nouns ; the first word after an em dash, semi-colon, or end punctuation; and any noun followed by a letter or number.

Title case is where major words are capitalized while minor words are lower case.

In APA style, major words are nouns, verbs, adjectives, pronouns, adverbs, or any word that is four letters or longer.

Minor words are articles, short prepositions, and conjunctions that are three letters or less.

(See section 5.7 of the Concise Guide to APA Style )

Paraphrasing

Refers to restating someone else's ideas or findings into your own words. Paraphrasing allows you to summarize information from one or more sources, compare and contrast information from multiple sources, and focus on the most important information from each source.

It is BEST to paraphrase information whenever possible rather than using direct quotations.

Paraphrased information must be cited in-text with either a parenthetical or narrative citation.

(See sections 8.23 and 8.24 of the Concise Guide to APA Style)

Reproduce words EXACTLY as written from another work (including your own). Quotations are best used in papers for when you want to reproduce an exact definition, when an author of a work has said something memorable, or when you want to respond to the exact wording (something someone said) from an author in your paper.

When not using a quotation for one of the above reasons, it is best to paraphrase information. Additionally, you should check with your instructor to see if they limit the number of quotations you are allowed to use.

Quotations must be cited in-text with either a parenthetical or narrative citation.

Short quotations consist of 40 words or less and should be incorporated into the text of your paper with quotation marks.

Long quotations consists of 40 words or more and do not use quotations marks. Instead, they should be incorporated into your paper as a block quotation. Block quotations begin on a new line, are double-spaced, and are indented 0.5 inches from the left hand margin of your paper.

(See sections 8.25 - 8.33 of the Concise Guide to APA Style)

Heading Levels

Heading Levels or "headings" are a way to organize information in APA papers and convey it clearly ( think of headings as "sections" and "subsections"). There are five levels of headings in APA Style, although for undergraduates it is rare to need to go past a Level 2 headings. If you are unsure if you need to use headings, check with your instructor.

Note: Do NOT label an introduction as "Introduction" in APA papers. The title of your paper acts as a de facto Level 1 Heading.

APA Publications in the Library

This guide pertains to the 7th edition of the APA Manual.

This guide is designed to support the citation and reference needs of USC students, staff, and faculty.  The 7th edition of the manual does make distinctions between formatting certain components for academic use over publication.  This guide will distinguish student/academic formatting where applicable. 

This guide is designed as a "quick" reference to common APA citation, reference and formatting criteria.  When in doubt, we encourage users to consult with the APA publication manual or APA website for further clarification as the authority on formatting.

What is the purpose of citations?

Citations help readers locate your sources. They help to continue the scholarly conversation. To learn more about how citations can help you avoid plagiarism, view this interactive tutorial: 

USC Library Lessons: Avoiding Plagiarism through Citations

When considering citations and references for your papers, you can ask yourself, "could someone find this information in the future?"

A client's personal file would not need a citation because your reader cannot go find that information again.  Census statistics would require a citation because your reader could go locate that information again.

APA requires FOUR ELEMENTS of every citation:

• Who- Author of content
• When- Date content was published
• What- Title of content
• Where- Publication information. This can be the website you got it from or the journal or book's publication information.

If any of the elements listed above are unavailable, check out "Missing Reference Information" from APA for more information.

• APA Style Website As part of our Style and Grammar Guidelines, we explain the basics of paper format, grammar, punctuation, in-text citations, references, bias-free language, and more. Much of what you used to find on the sixth edition blog, you can now find on the APA Style website.

Who Should Use APA Style?

APA style is used by social science disciplines such as communication studies, economics, education, psychology, and sociology; it is also used by business and nursing.

What is APA Style?

APA style, created by the American Psychological Association, is a set of rules for formatting manuscripts, including research papers.

In APA, you must cite sources that you have paraphrased, quoted or otherwise used to write your research paper. Cite your sources in two places:

• In the body of your paper where you add a brief in-text citation .
• In the References list at the end of your paper where you give more complete information for the source.
• APA 7th ed. Sample Paper
• APA Style Paper template (Microsoft Word)
• APA 7th. ed. Journal Article Reference Checklist
• APA 7th. ed. Student Paper Checklist

APA Style Guide (7th Edition)

Four Elements of a Reference

A reference generally has these four elements: author, date, title, and source. Each element answers a question and is listed in your citation in the following order:

• author : Who is responsible for this work?
• date : When was this work published?
• title : What is the work called?
• source : Where can I retrieve this work?

What Is APA?

APA stands for American Psychological Association and is a common formatting style for publications, including research papers, in the social sciences. APA style has unique formats for in-text citations and reference pages. Its style and guidelines increase the ease of reading comprehension for viewers as well as ensure consistent presentation of content and written material.

In APA, you must cite sources that you have paraphrased, quoted, or otherwise refer to in your research paper.

Cite your sources in two places:

• In the body of your paper with an in-text citation .
• In the Reference list at the end of your paper.

• Quick How-Tos of APA Citation - Short and accessible explanation and examples of basic citation.
• Purdue's APA Guide (Online Writing Lab - OWL) - A thorough collection of APA citation and style examples.

All citations should be double-spaced and have a hanging indent in a Reference list. A "hanging indent" means that each subsequent line after the first line of your citation should be indented by 0.5 inches.

DOIs and Permalinks

For sources found using Library Search or a database, use the DOI (Digital Object Identifier) , which is a type of permalink assigned to journal articles published online. If you have both a permalink and a DOI for an article, use the DOI.

The "Permalink" button in Library Search is indicated by an icon made of two connected, gray links. With the large number of sources available online, it is common for citations to include a URL. It is important to note, however, that the URL you include for any of your citations should be a permanent URL (or permalink), one that will stay active past the time that you are on that webpage.

Narrative citations:  Grady et al. (2019) and Jerrentrup et al. (2018)

• If a journal article has a DOI, include the DOI in the reference.
• If the journal article does not have a DOI and is from an academic research database, end the reference after the page range (for an explanation of why, see the  database information  page). The reference in this case is the same as for a print journal article.
• Do not include database information in the reference unless the journal article comes from a database that publishes original, proprietary content, such as UpToDate (see an example on the  database information  page).
• If the journal article does not have a DOI but does have a URL that will resolve for readers (e.g., it is from an online journal that is not part of a database), include the URL of the article at the end of the reference.
• If the journal article has an article number instead of a page range, include the article number instead of the page range (as shown in the Jerrentrup et al. example).

Parenthetical citations:  (Rabinowitz, 2019; Sapolsky, 2017)

Narrative citations:  Rabinowitz (2019) and Sapolsky (2017)

• If the book includes a DOI, include the DOI in the reference after the publisher name.
• Do not include the publisher location.
• If the book does not have a DOI and comes from an academic research database, end the book reference after the publisher name. Do not include  database information  in the reference. The reference in this case is the same as for a print book.

Parenthetical citations:  (Schaefer & Shapiro, 2019; Schulman, 2019)

Narrative citations:  Schaefer and Shapiro (2019) and Schulman (2019)

• If a magazine article has a DOI, include the DOI in the reference.
• If the magazine article does not have a DOI and is from an academic research database, end the reference after the page range. Do not include  database information  in the reference. The reference in this case is the same as for a print magazine article.
• If the magazine article does not have a DOI but does have a URL that will resolve for readers (e.g., it is from an online magazine that is not part of a database), include the URL of the article at the end of the reference.
• If the magazine article does not have volume, issue, and/or page numbers (e.g., because it is from an online magazine), omit the missing elements from the reference (as in the Schulman example).

Parenthetical citation:  (Carey, 2019)

Narrative citation:  Carey (2019)

• If the newspaper article is from an academic research database, end the reference after the page range. Do not include  database information  in the reference. The reference in this case is the same as for a print newspaper article.
• If the newspaper article has a URL that will resolve for readers (e.g., it is from an online newspaper), include the URL of the article at the end of the reference.
• If the newspaper article does not have volume, issue, and/or page numbers (e.g., because it is from an online newspaper), omit the missing elements from the reference, as shown in the example.
• If the article is from a news website (e.g., CNN, HuffPost)—one that does not have an associated daily or weekly newspaper—use the format for a  webpage on a website  instead.

Parenthetical citation:  (Aron et al., 2019)

Narrative citation:  Aron et al. (2019)

• If the edited book chapter includes a DOI, include the chapter DOI in the reference after the publisher name.
• If the edited book chapter does not have a DOI and comes from an academic research database, end the edited book chapter reference after the publisher name. Do not include  database information  in the reference. The reference in this case is the same as for a print edited book chapter.
• Do not create references for chapters of authored books. Instead, write a reference for the whole book and cite the chapter in the text if desired (e.g., Kumar, 2017, Chapter 2).

Parenthetical citation:  (Merriam-Webster, n.d.)

Narrative citation:  Merriam-Webster (n.d.)

• Because entries in  Merriam-Webster’s Dictionary  are updated over time and are not archived, include a  retrieval date  in the reference.
• Merriam-Webster is both the author and the publisher, so the name appears in the author element only to avoid repetition.
• To quote a dictionary definition, view the pages on quotations and  how to quote works without page numbers  for guidance. Additionally, here is an example:  Culture  refers to the “customary beliefs, social forms, and material traits of a racial, religious, or social group” (Merriam-Webster, n.d., Definition 1a).

Parenthetical citation:  (National Cancer Institute, 2019)

Narrative citation:  National Cancer Institute (2019)

The specific agency responsible for the report appears as the author. The names of parent agencies not present in the  group author name  appear in the source element as the publisher. This creates concise in-text citations and complete reference list entries.

Parenthetical citation:  (Harvard University, 2019)

Narrative citation:  Harvard University (2019)

• Use the name of the account that uploaded the video as the author.
• If the account did not actually create the work, explain this in the text if it is important for readers to know. However, if that would mean citing a source that appears unauthoritative, you might also look for the author’s YouTube channel, official website, or other social media to see whether the same video is available elsewhere.

Parenthetical citations:  (APA Databases, 2019; Gates, 2019)

Narrative citations:  APA Databases (2019) and Gates (2019)

• Present the name of the individual or group author the same as you would for any other reference. Then provide the Twitter handle (beginning with the @ sign) in square brackets, followed by a period.
• Provide the first 20 words of the tweet as the title. Count a URL, a hashtag, or an emoji as one word each, and include them in the reference if they fall within the first 20 words.
• If the tweet includes an image, a video, a poll, or a thumbnail image with a link, indicate that in brackets after the title: [Image attached], [Video attached], [Thumbnail with link attached].
• The same format used for Twitter is also used for Instagram.  

Parenthetical citation:  (News From Science, 2019)

Narrative citation:  News From Science (2019)

• Provide the first 20 words of the Facebook post as the title. Count a URL or other link, a hashtag, or an emoji as one word each, and include them in the reference if they fall within the first 20 words. 
• If a status update includes images, videos, thumbnail links to outside sources, or content from another Facebook post (such as when sharing a link), indicate that in square brackets.

Parenthetical citations:  (Fagan, 2019; National Institute of Mental Health, 2018; Woodyatt, 2019; World Health Organization, 2018)

Narrative citations:  Fagan (2019), National Institute of Mental Health (2018), Woodyatt (2019), and World Health Organization (2018)

• Provide as specific a  date  as is available on the webpage. This might be a year only; a year and month; or a year, month, and day.
• Italicize the title of a webpage.
• When the author of the webpage and the publisher of the website are the same, omit the publisher name to avoid repetition (as in the World Health Organization example).
• When contents of a page are meant to be updated over time but are not archived, include a  retrieval date  in the reference (as in the Fagan example).
• Use the webpage on a website format for articles from news websites such as CNN and HuffPost (these sites do not have associated daily or weekly newspapers). Use the  newspaper article category  for articles from newspaper websites such as  The New York Times  or  The Washington Post .
• Create a reference to an open educational resources (OER) page only when the materials are available for download directly (i.e., the materials are on the page and/or can be downloaded as PDFs or other files). If you are directed to another website, create a reference to the specific webpage on that website where the materials can be retrieved. Use this format for material in any OER repository, such as OER Commons, OASIS, or MERLOT.
• Do not create a reference or in-text citation for a whole website. To mention a website in general, and not any particular information on that site, provide the name of the website in the text and include the URL in parentheses. For example, you might mention that you used a website to create a survey.

The following supplemental example references are mention in the  Publication Manual:

• retracted journal or magazine article
• edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM)
• edition of the International Statistical Classification of Diseases and Related Health Problems (ICD)
• religious work
• annotated religious work

Archival document and collections are not presented in the  APA Publication Manual, Seventh Edition . This content is available only on the APA Style website .  This guidance has been expanded from the 6th edition.

Archival sources include letters, unpublished manuscripts, limited-circulation brochures and pamphlets, in-house institutional and corporate documents, clippings, and other documents, as well as such nontextual materials as photographs and apparatus, that are in the personal possession of an author, form part of an institutional collection, or are stored in an archive such as the Archives of the History of American Psychology at the University of Akron or the APA Archives. For any documents like these that are available on the open web or via a database (subscription or nonsubscription), follow the reference templates shown in Chapter 10 of the Publication Manual.

The general format for the reference for an archival work includes the author, date, title, and source. The reference examples shown on this page may be modified for collections requiring more or less specific information to locate materials, for different types of collections, or for additional descriptive information (e.g., a translation of a letter). Authors may choose to list correspondence from their own personal collections, but correspondence from other private collections should be listed only with the permission of the collector.

Keep in mind the following principles when creating references to archival documents and collections:

• As with any reference, the purpose is to direct readers to the source, despite the fact that only a single copy of the document may be available and readers may have some difficulty actually seeing a copy.
• Include as much information as is needed to help locate the item with reasonable ease within the repository. For items from collections with detailed finding aids, the name of the collection may be sufficient; for items from collections without finding aids, more information (e.g., call number, box number, file name or number) may be necessary to help locate the item.
• If several letters are cited from the same collection, list the collection as a reference and provide specific identifying information (author, recipient, and date) for each letter in the in-text citations (see Example 3).
• Use square brackets to indicate information that does not appear on the document.
• Use “ca.” (circa) to indicate an estimated date (see Example 5).
• Use italics for titles of archival documents and collections; if the work does not have a title, provide a description in square brackets without italics.
• Separate elements of the source (e.g., the name of a repository, library, university or archive, and the location of the university or archive) with commas. End the source with a period.
• If a publication of limited circulation is available in libraries, the reference may be formatted as usual for published material, without the archival source.
• Note that private letters (vs. those in an archive or repository) are considered personal communications and cited in the text only.

1. Letter from a repository

Frank, L. K. (1935, February 4). [Letter to Robert M. Ogden]. Rockefeller Archive Center (GEB Series 1.3, Box 371, Folder 3877), Tarrytown, NY, United States.

Read the full APA guidelines on citing ChatGPT 

OpenAI. (2023).  ChatGPT  (Mar 14 version) [Large language model].  https://chat.openai.com/chat

• Parenthetical citation:  (OpenAI, 2023)
• Narrative citation:  OpenAI (2023)

Author:  The author of the model is OpenAI.

Date:  The date is the year of the version you used. Following the template in Section 10.10, you need to include only the year, not the exact date. The version number provides the specific date information a reader might need.

Title:  The name of the model is “ChatGPT,” so that serves as the title and is italicized in your reference, as shown in the template. Although OpenAI labels unique iterations (i.e., ChatGPT-3, ChatGPT-4), they are using “ChatGPT” as the general name of the model, with updates identified with version numbers.

The version number is included after the title in parentheses. The format for the version number in ChatGPT references includes the date because that is how OpenAI is labeling the versions. Different large language models or software might use different version numbering; use the version number in the format the author or publisher provides, which may be a numbering system (e.g., Version 2.0) or other methods.

Bracketed text  is used in references for additional descriptions when they are needed to help a reader understand what’s being cited. References for a number of common sources, such as journal articles and books, do not include bracketed descriptions, but things outside of the typical peer-reviewed system often do. In the case of a reference for ChatGPT, provide the descriptor “Large language model” in square brackets. OpenAI describes ChatGPT-4 as a “large multimodal model,” so that description may be provided instead if you are using ChatGPT-4. Later versions and software or models from other companies may need different descriptions, based on how the publishers describe the model. The goal of the bracketed text is to briefly describe the kind of model to your reader.

Source:  When the publisher name and the author name are the same, do not repeat the publisher name in the source element of the reference, and move directly to the URL. This is the case for ChatGPT. The URL for ChatGPT is  https://chat.openai.com/chat . For other models or products for which you may create a reference, use the URL that links as directly as possible to the source (i.e., the page where you can access the model, not the publisher’s homepage).

What to include and what to exclude

Works included in a reference list.

The reference list provides a reliable way for readers to identify and locate the works cited in a paper. APA Style papers generally include reference lists, not  bibliographies.

In general, each work cited in the text must appear in the reference list, and each work in the reference list must be cited in the text. Check your work carefully before submitting your manuscript or course assignment to ensure no works cited in the text are missing from the reference list and vice versa, with only the following exceptions.

Works Excluded From a Reference List

There are a few kinds of works that are not included in a reference list. Usually a work is not included because readers cannot recover it or because the mention is so broad that readers do not need a reference list entry to understand the use.

Information on works included in a reference list is covered in Sections 2.12 and 8.4 of the  APA Publication Manual, Seventh Edition

*This guidance has been expanded from the 6th edition.*

• Personal communications  such as emails, phone calls, or text messages are cited in the text only, not in the reference list, because readers cannot retrieve personal communications.
• General mentions of whole websites, whole periodicals, and common software and apps in the text do not require in-text citations or reference list entries because the use is broad and the source is familiar.
• The source of an epigraph does not usually appear in the reference list unless the work is a scholarly book or journal. For example, if you open the paper with an inspirational quotation by a famous person, the source of the quotation does not appear in the reference list because the quotation is meant to set the stage for the work, not substantiate a key point.   
• Quotations from research participants in a study you conducted can be presented and discussed in the text but do not need citations or reference list entries. Citations and reference list entries are not necessary because the quotations are part of your original research. They could also compromise participants’ confidentiality, which is an ethical violation.
• References included in a meta-analysis, which are marked with an asterisk in the reference list, may be cited in the text (or not) at the author’s discretion. This exception is relevant only to authors who are conducting a meta-analysis.

DOIs and URLs

The DOI or URL is the final component of a reference list entry. Because so much scholarship is available and/or retrieved online, most reference list entries end with either a DOI or a URL.

• A DOI is a unique alphanumeric string that identifies content and provides a persistent link to its location on the internet. DOIs can be found in database records and the reference lists of published works.
• A URL specifies the location of digital information on the internet and can be found in the address bar of your internet browser. URLs in references should link directly to the cited work when possible.

Follow these guidelines for including DOIs and URLs in references:

• Include a DOI for all works that have a DOI, regardless of whether you used the online version or the print version.
• If a print work does not have a DOI, do not include any DOI or URL in the reference.
• If an online work has both a DOI and a URL, include only the DOI.
• For works without DOIs from websites (not including academic research databases), provide a URL in the reference (as long as the URL will work for readers).
• For works without DOIs from most  academic research databases , do not include a URL or database information in the reference because these works are widely available. The reference should be the same as the reference for a print version of the work.
• For works from databases that publish original, proprietary material available only in that database (such as the UpToDate database) or for works of limited circulation in databases (such as monographs in the ERIC database), include the name of the database or archive and the URL of the work. If the URL requires a login or is session-specific (meaning it will not resolve for readers), provide the URL of the database or archive home page or login page instead of the URL for the work. See the page on including  database information in references  for more information. 
• If the URL is no longer working or no longer provides readers access to the content you intend to cite, follow the guidance for works with  no source .
• Other alphanumeric identifiers such as the International Standard Book Number (ISBN) and the International Standard Serial Number (ISSN) are not included in APA Style references.

Follow these guidelines to format DOIs and URLs:

• Present both DOIs and URLs as hyperlinks (i.e., beginning with “http:” or “https:”).
• Because a hyperlink leads readers directly to the content, it is not necessary to include the words “Retrieved from” or “Accessed from” before a DOI or URL.
• It is acceptable to use either the default display settings for hyperlinks in your word-processing program (e.g., usually blue font, underlined) or plain text that is not underlined.
• Leave links live if the work is to be published or read online.
• Follow the current recommendations of the International DOI Foundation to format DOIs in the reference list, which as of this publication is as follows:

https://doi.org/ xxxxx

• The string “https://doi.org/” is a way of presenting a DOI as a link, and “xxxxx” refers to the DOI number.
• The preferred format of the DOI has changed over time. Although older works use previous formats (e.g., “http:/dx.doi.org/” or “doi:” or “DOI:” before the DOI number), in your reference list, standardize DOIs into the current preferred format for all entries. For example, use  https://doi.org/10.1037/a0040251  in your reference even though that article, published in 2016, presented the number in an older format.
• Copy and paste the DOI or URL from your web browser directly into your reference list to avoid transcription errors. Do not change the capitalization or punctuation of the DOI or URL. Do not add line breaks manually to the hyperlink; it is acceptable if your word-processing program automatically adds a break or moves the hyperlink to its own line.
• Do not add a period after the DOI or URL because this may interfere with link functionality.

When a DOI or URL is long or complex, you may use shortDOIs or shortened URLs if desired.

• Use the  shortDOI service  provided by the International DOI Foundation to create shortDOIs. A work can have only one DOI and only one shortDOI; the shortDOI service will either produce a new shortDOI for a work that has never had one or retrieve an existing shortDOI.
• Some websites provide their own branded shortened URLs, and independent URL shortening services are available as well. Any shortened URL is acceptable in a reference as long as you check the link to ensure that it takes you to the correct location.

Free APA Citation Generator

Generate citations in APA format quickly and automatically, with MyBib!

🤔 What is an APA Citation Generator?

An APA citation generator is a software tool that will automatically format academic citations in the American Psychological Association (APA) style.

It will usually request vital details about a source -- like the authors, title, and publish date -- and will output these details with the correct punctuation and layout required by the official APA style guide.

Formatted citations created by a generator can be copied into the bibliography of an academic paper as a way to give credit to the sources referenced in the main body of the paper.

👩‍🎓 Who uses an APA Citation Generator?

College-level and post-graduate students are most likely to use an APA citation generator, because APA style is the most favored style at these learning levels. Before college, in middle and high school, MLA style is more likely to be used. In other parts of the world styles such as Harvard (UK and Australia) and DIN 1505 (Europe) are used more often.

🙌 Why should I use a Citation Generator?

Like almost every other citation style, APA style can be cryptic and hard to understand when formatting citations. Citations can take an unreasonable amount of time to format manually, and it is easy to accidentally include errors. By using a citation generator to do this work you will:

• Save a considerable amount of time
• Ensure that your citations are consistent and formatted correctly
• Be rewarded with a higher grade

In academia, bibliographies are graded on their accuracy against the official APA rulebook, so it is important for students to ensure their citations are formatted correctly. Special attention should also be given to ensure the entire document (including main body) is structured according to the APA guidelines. Our complete APA format guide has everything you need know to make sure you get it right (including examples and diagrams).

⚙️ How do I use MyBib's APA Citation Generator?

Our APA generator was built with a focus on simplicity and speed. To generate a formatted reference list or bibliography just follow these steps:

• Start by searching for the source you want to cite in the search box at the top of the page.
• MyBib will automatically locate all the required information. If any is missing you can add it yourself.
• Your citation will be generated correctly with the information provided and added to your bibliography.
• Repeat for each citation, then download the formatted list and append it to the end of your paper.

MyBib supports the following for APA style:

How to cite in APA Style (7th edition)

(Looking for the old 6th edition guide?)

Most academic writing cites others' ideas and research, for several reasons:

• Sources that support your ideas give your paper authority and credibility
• Shows you have researched your topic thoroughly
• Crediting sources protects you from plagiarism
• A list of sources can be a useful record for further research

Different academic disciplines prefer different citation styles, most commonly  APA and MLA styles. 

Besides these styles, there are  Chicago ,  Turabian ,  AAA ,  AP , and more. Only use the most current edition of the citation style.

Ask your instructors which citation style they want you to use for assignments.

When to cite.

To avoid plagiarism, provide a citation for ideas that are not your own:

• Direct quotation
• Paraphrasing of a quotation, passage, or idea
• Summary of another's idea or research
• Specific reference to a fact, figure, or phrase

You do not need to cite common knowledge (ex. George Washington was the first President of the United States) or proverbs unless you are using a direct quotation. When in doubt, cite your source.

Fundamentals of APA

American Psychological Association (APA) style includes  parenthetical in-text citations  and a  reference list . 

APA uses  parenthetical citations  as its form of in-text citation. Provide a parenthetical citation  before the period  directly following the information you are citing. These citations should correspond to a more detailed citation in the reference list but only need to specify a page number if directly quoting or borrowing from the source material. The essential elements for this in-text citation are the author's last name and the date for the specific publications. The last name may be omitted if the sentence states or makes clear the source material.

APA uses a  reference list ,  an alphabetized list of sources following the end of the book or paper,  for its complete list of sources referenced. This list should be titled "References" in bold and alphabetized by the first item in the citation, which, in most cases, is the author's last name. Each reference from this list must be cited in your paper and vice versa.

Basic Format

Author Last Name, Author First Initial. (Year of publication). Title . Publisher Name.

Print Articles

Author Last Name, Author First Initial, & Author Last Name, Author First Initial. (Year). Article Title. Periodical Title , volume number(issue number), pages.

Electronic Articles

Author Last Name, Author First Initial. (Year). Article Title. Periodical Title , volume number(issue number), pages. doi or static url.

Physical Images/Artwork

Artist Last Name, Artist First Initial. (Year). Artwork Title [medium]. Host Institution Name, City, State, Country. URL of institution.

Electronic Images/Artwork

Artist Last Name, Artist First Initial. (Year). Image Title [medium]. Source Title. URL of image.

In-text Citation Examples

Standard case :

"Lorem   ipsum  dolor sit  amet ,  consectetur   adipiscing   elit" (Last name, 2000, p.10).

If the author is not available , the title of the source may be used:

Lorem   ipsum  dolor sit  amet ,  consectetur   adipiscing   elit ("Source title", 2000, pp.10-11).

If multiple authors cited have the same last name , use the author's first initial along with their last name:

"Lorem   ipsum  dolor sit  amet ,  consectetur   adipiscing   elit" (E. Bronte, 1847, p.10).

Lorem   ipsum  dolor sit  amet ,  consectetur   adipiscing   elit (C. Bronte, 1847, p.10).

Being responsible while researching

When you’re writing a research paper or creating a research project, you will probably use another individual’s work to help develop your own assignment. A good researcher or scholar uses another individual’s work in a responsible way. This involves indicating that the work of other individuals is included in your project (i.e., citing), which is one way to prevent plagiarism.

Plagiarism? What is it?

The word plagiarism is derived from the Latin word, plagiare , which means “to kidnap.” The term has evolved over the years to now mean the act of taking another individual’s work and using it as your own, without acknowledging the original author (American Psychological Association, 2020 p. 21). Plagiarism can be illegal and there can be serious ramifications for plagiarizing someone else’s work. Thankfully, plagiarism can be prevented. One way it can be prevented is by including citations and references in your research project. Want to make them quickly and easily? Try the Citation Machine citation generator, which is found on our homepage.

All about citations & references

Citations and references should be included anytime you use another individual’s work in your own assignment. When including a quote, paraphrased information, images, or any other piece of information from another’s work, you need to show where you found it by including a citation and a reference. This guide explains how to make them.

APA style citations are added in the body of a research paper or project and references are added to the last page.

Citations , which are called in-text citations, are included when you’re adding information from another individual’s work into your own project. When you add text word-for-word from another source into your project, or take information from another source and place it in your own words and writing style (known as paraphrasing), you create an in-text citation. These citations are short in length and are placed in the main part of your project, directly after the borrowed information.

References are found at the end of your research project, usually on the last page. Included on this reference list page is the full information for any in-text citations found in the body of the project. These references are listed in alphabetical order by the author's last name.

An APA in-text citation includes only three items: the last name(s) of the author(s), the year the source was published, and sometimes the page or location of the information. References include more information such as the name of the author(s), the year the source was published, the full title of the source, and the URL or page range.

Why is it important to include citations & references

Including APA citations and references in your research projects is a very important component of the research process. When you include citations, you’re being a responsible researcher.

Common ways students and scholars accidentally plagiarize

Believe it or not, there are instances when you could attempt to include in-text and full references in the appropriate places, but still accidentally plagiarize. Here are some common mistakes to be aware of:

Mistake #1 - Misquoting sources: If you plan to use a direct quote, make sure you copy it exactly as is. Sure, you can use part of the full quote or sentence, but if you decide to put quotation marks around any words, those words should match exactly what was found in the original source. Here’s a line from The Little Prince , by Antoine de Saint-Exupéry:

“Grown-ups never understand anything by themselves, and it is tiresome for children to be always and forever explaining things to them.”

Here’s an acceptable option:

“Grown-ups never understand anything by themselves,” stated de Saint-Exupéry (1943, p. 3).

Here’s a misquote:

“Grown-ups barely ever understand anything by themselves,” stated de Saint-Exupéry (1943, p. 3).

Notice the slight change in the words. The incorrect phrasing is an instance of accidental plagiarism.

Mistake #2 - Problems with paraphrasing: When we paraphrase, we restate information using our own words and writing style. It’s not acceptable to substitute words from the original source with synonyms.

Let’s use the same sentence from The Little Prince .

A correct paraphrase could be:

de Saint-Exupéry (1943) shares various ways adults frustrate children. One of the biggest being that kids have to explain everything. It’s too bad adults are unable to comprehend anything on their own (p. 3).

An incorrect paraphrase would be:

de Saint-Exupéry (1943) shares that adults never understand anything by themselves, and it is exhausting for kids to be always and forever clarifying things to them (p.3).

Notice how close the incorrect paraphrase is from the original. This is an instance of accidental plagiarism.

Make sure you quote and paraphrase properly in order to prevent accidental plagiarism.

If you’re having a difficult time paraphrasing properly, it is acceptable to paraphrase part of the text AND use a direct quote. Here’s an example:

de Saint-Exupery (1943) shares various ways adults frustrate children. One of the biggest being that kids have to explain everything, and “it is tiresome for children to be always and forever explaining things to them” (p. 3).

Information About APA

Who created it.

The American Psychological Association is an organization created for individuals in the psychology field. With close to 121,000 members, they provide educational opportunities, funding, guidance, and research information for everything psychology-related. They also have numerous high-quality databases, peer-reviewed journals, and books that revolve around mental health.

The American Psychological Association is also credited with creating their own specific citation and reference style. Today, this format is used by individuals not only in the psychology field, but many other subject areas as well. Education, economics, business, and social sciences also use APA style quite frequently. Click here for more information . This guide covers general information about the style, but is not affiliated with the American Psychological Association.

Why was this style created?

This format was first developed in 1929 to form a standardized way for researchers in science fields to document their sources. Prior to the inception of these standards and guidelines, individuals were recognizing the work of other authors by including bits and pieces of information in random order. There wasn’t a set way to format citations and references. You can probably imagine how difficult it was to understand the sources that were used for research projects!

Having a standard format for citing sources allows readers to glance at a citation or APA reference and easily locate the title, author, year published, and other critical pieces of information needed to understand a source.

The evolution of this style

The guide below is based on APA style 7th edition, which was released in 2020. In previous versions of APA format, researchers and scholars were required to include the publisher location for books and the date that an electronic resource was accessed. Both are no longer required to be included.

Details on the differences between the 6th and 7th editions is addressed later in this guide.

Citations & References

The appearance of citations & references.

The format for references varies, but most use this general format:

%%Author’s Last name, First initial. (Date published). Title . URL

Researchers and scholars must look up the proper format for the source that they’re attempting to cite. Books have a certain format, websites have a different format, periodicals have a different format, and so on. Scroll down to find the proper format for the source you’re citing or referencing.

If you would like help citing your sources, CitationMachine.com has a citation generator that will help make the APA citation process much easier for you. To start, simply click on the source type you're citing:

• Journal articles

In-text citations

An APA in-text citation is included in research projects in three instances: When using a direct quote, paraphrasing information, or simply referring to a piece of information from another source.

Quite often, researchers and scholars use a small amount of text, word for word, from another source and include it in their own research projects. This is done for many reasons. Sometimes, another author’s words are so eloquently written that there isn’t a better way to rephrase it yourself. Other times, the author’s words can help prove a point or establish an understanding for something in your research project. When using another author’s exact words in your research project, include an APA in-text citation directly following it.

In addition to using the exact words from another source and placing them into your project, these citations are also added anytime you paraphrase information. Paraphrasing is when you take information from another source and rephrase it, in your own words.

When simply referring to another piece of information from another source, also include a citation directly following it.

Citations in the text are found near a direct quote, paraphrased information, or next to a mention of another source. To see examples of some narrative/ parenthetical citations in action, look at the image above, under “All About Citations & References.”

Note: *Only include the page or paragraph number when using a direct quote or paraphrase. Page numbers have a p. before the number, pp. before the page range, and para. before the paragraph number. This information is included to help the reader locate the exact portion of text themselves. It is unnecessary to include this information when you’re simply referring to another source.

Examples of APA in-text citations:

“Well, you’re about to enter the land of the free and the brave. And I don’t know how you got that stamp on your passport. The priest must know someone” (Tóibín, 2009, p. 52).

Student teachers who use technology in their lessons tend to continue using technology tools throughout their teaching careers (Kent & Giles, 2017, p. 12).

If including the author’s name in the sentence, place the year in the parentheses directly next to his or her name. Add the page number at the end, unless it’s a source without any pages or paragraph numbers (See Section 8.10 of the Publication manual for more details).

In-text citation APA example:

According to a study done by Kent and Giles (2017), student teachers who use technology in their lessons tend to continue using technology tools throughout their teaching careers.

The full references, or citations, for these sources can be found on the last part of a research project, titled the “References.”

Here’s how to create in-text citations for specific amounts of authors:

APA citation with no author

When the source lacks an author’s name, place the title, year, and page number (if available) in the text. The title should be in italics if it sits alone (such as a movie, brochure, or report). If the source is part of a whole (as many web pages and articles are), place the title in quotation marks without italics (See Section 8.14 of the Publication manual ).

Structure of an APA format citation in the text narratively, with the author's name missing:

Title of Source (Year) or “Title of Source” (Year)

Structure of an APA style format citation, in parentheses at the end of the sentence, with the author’s name missing: (Title of Source, Year) or (“Title of Source,” Year)

Structure for one author

In the text, narratively: Last name of Author (Year)...(page number).

In parentheses, at the end of the sentence: (Last name of Author, Year, page number).

Structure for two authors

Place the authors in the order they appear on the source. Only use the ampersand in the parenthetical citations (see Section 8.17 of the Publication manual ). Use ‘and’ to separate the author names if they’re in the text of the sentence.

In the text, narratively: Last name of Author 1 and Last name of Author 2 (Year)....(page number).

In parentheses, at the end of the sentence: (Last name of Author 1 & Last name of Author 2, Year, page number).

Structure for three or more authors

Only include the first listed author’s name in the first and any subsequent citations. Follow it with et al.

(Last name Author 1 et al., Year, page number)

(Agbayani et al., 2020, p. 99)

Last name of Author 1 et al. (Year)...(page).

Agbayani et al. (2020)...(p. 99)

One author, multiple works, same year

What do you do when you want to cite multiple works by an author, and the sources all written in the same year?

Include the letters ‘a’ ‘b’ ‘c’ and so on after the year in the citation.

(Jackson, 2013a)

Jackson (2013a)

Writers can even lump dates together.

Example: Jackson often studied mammals while in Africa (2013a, 2013b).

On the APA reference page, include the same letters in the full references.

Groups and organizations

Write out the full name of the group or organization in the first citation and place the abbreviation next to it in brackets. If the group or organization is cited again, only include the abbreviation. If it doesn’t have an abbreviation associated with it, write out the entire organization’s name each and every time (see Section 8.21 of the Publication manual ).

First APA citation for an organization with an abbreviation: (World Health Organization [WHO], Year)

World Health Organization (WHO, Year)

Notice in the example directly above, the name of the organization is written out in full in the text of the sentence, and the abbreviation is placed in parentheses next to it.

Subsequent APA citations in the text for an organization with an abbreviation: (WHO, Year) OR WHO (Year)

All citations in the text for an organization without an abbreviation: (Citation Machine, Year) or Citation Machine (Year)

One in-text citation, multiple works

Sometimes you’ll need to cite more than one work within an in-text citation. Follow the same format (author, year) format but place semicolons between works (p. 263).

(Obama, 2016; Monroe et al., 1820; Hoover & Coolidge, 1928)

Reference list citation components

References display the full information for all the citations found in the body of a research project.

Some things to keep in mind when it comes to the references:

• All references sit together on their own page, which is usually the last page(s) of a paper.
• Title the page ‘References’
• Place ‘References’ in the center of the page and bold it. Keep the title in the same font and size as the references. Do not italicize, underline, place the title in quotation marks, or increase the font size.
• The entire page is double spaced.
• All references are listed in alphabetical order by the first word in the reference, which is usually the author’s last name. If the source lacks an author, alphabetize the source by the title (ignore A, An, or The)
• All references have a hanging indent, meaning that the second line of text is indented in half an inch. See examples throughout this guide.
• Remember, each and every citation in the text of the paper MUST have a full reference displayed in the reference list. The citations in the text provide the reader with a quick glimpse about the sources used, but the references in the reference list provide the reader with all the information needed to seek out the source themselves.

Learn more about each component of the reference citation and how to format it in the sections that follow. See an APA sample paper reference list at the end of this entire section.

Author’s names

The names of authors are written in reverse order. Include the initials for the first and middle names. End this information with a period (see Section 9.8 of the Publication manual ).

Format: Last name, F. M.

• Angelou, M.
• Doyle, A. C.

Two or more authors

When two or more authors work together on a source, write them in the order in which they appear on the source. You can name up to 20 authors in the reference. For sources with 2 to 20 authors, place an ampersand (&) before the final author. Use this format:

Last name, F. M., & Last name, F. M.

Last name, F. M., Last name, F. M., Last name, F. M., Last name, F. M., & Last name, F. M.

Kent, A. G., Giles, R. M., Thorpe, A., Lukes, R., Bever, D. J., & He, Y.

If there are 21 or more authors listed on a source, only include the first 19 authors, add three ellipses, and then add the last author’s name.

Roberts, A., Johnson, M. C., Klein, J., Cheng, E. V., Sherman, A., Levin, K. K. , ...Lopez, G. S.

If you plan on using a free APA citation tool, like the one at CitationMachine.com, the names of the authors will format properly for you.

###No authors

If the source lacks an author, place the title in the first position in the reference (Section 9.12 of the Publication manual ). When the source’s title begins with a number (Such as 101 Dalmatians ), place the reference alphabetically as if the number was spelled out. 101 Dalmatians would be placed in the spot where ‘One hundred’ would go, but keep the numbers in their place.

Additionally, if the title begins with the words ‘A’, ‘An,’ or ‘The,’ ignore these words and place the title alphabetically according to the next word.

See the “Titles” section below for more information on formatting the title of sources.

###Corporate/Organization authors

On an APA reference page, corporate authors are always written out in full. In the text of your paper, you may have some abbreviations (such as UN for United Nations), but in the full references, always include the full names of the corporation or organization (following Section 9.11 of the official Publication manual ).

%%United Nations. (2019). Libya: $202 million needed to bring life-saving aid to half a million people hit by humanitarian crisis. https://news.un.org/en/story/2019/02/1031981

Publication date & retrieval date

Directly after the author’s name is the date the source was published. Include the full date for newspapers and magazine articles, and only the year for journals and all other sources. If no date is found on the source, include the initials, n.d. for “no date.”

%% Narducci, M. (2017, May 19). City renames part of 11th Street Ed Snider Way to honor Flyers founder. The Philadelphia Inquirer . http://www.philly.com/

If using our APA Citation Machine, our citation generator will add the correct format for you automatically.

Giving a retrieval date is not needed unless the online content is likely to be frequently updated and changed (e.g., encyclopedia article, dictionary entry, Twitter profile, etc.).

%%Citation Machine [@CiteMachine]. (n.d.). Tweets [Twitter profile]. Twitter. Retrieved October 10, 2019, from https://twitter.com/CiteMachine

When writing out titles for books, articles, chapters, or other non-periodical sources, only capitalize the first word of the title and the first word of the subtitle. Names of people, places, organizations, and other proper nouns also have the first letter capitalized. For books and reports, italicize the title in the APA citation.

Strange case of Dr. Jekyll and Mr. Hyde.

Roots: The saga of an American family.

For articles and chapters in APA referencing, do not italicize the title.

Wake up the nation: Public libraries, policy making, and political discourse.

For newspapers, magazines, journals, newsletters, and other periodicals, capitalize the first letter in each word and italicize the title.

The Seattle Times.

A common question is whether to underline your title or place it in italics or quotation marks in the reference list. Here’s a good general rule: When a source sits alone and is not part of a larger whole, place the title in italics. If the source does not sit alone and is part of a larger whole, do not place it in italics.

Books, movies, journals, and television shows are placed in italics since they stand alone. Songs on an album, episodes of television shows, chapters in books, and articles in journals are not placed in italics since they are smaller pieces of larger wholes.

The Citation Machine citation generator will format the title in your citations automatically.

Additional information about the title

If you feel it would be helpful to include additional information about the source type, include a descriptive noun or two in brackets immediately following the title. Capitalize the first letter.

%%Kennedy, K., & Molen, G. R. (Producers), & Spielberg, S. (Director). (1993). Jurassic Park [Film]. USA: Universal.

Besides [Film], other common notations include:

• [Audio podcast]
• [Letter to the editor]
• [Television series episode]
• [Facebook page]
• [Blog post]
• [Lecture notes]
• [PowerPoint presentation]
• [Video file]

If you are using Citation Machine citing tools, additional information about the title is automatically added for you.

Publisher information

For books and reports, include the publisher name but not the location (see Section 9.29 of the Publication manual ). Older editions of the style required the city, state and/or country, but this hasn't been the case since the 7th edition was released.

It is not necessary to include the entire name of the publisher. It is acceptable to use a brief, intelligible form. However, if Books or Press are part of the publisher’s names, keep these words in the reference. Other common terms, such as Inc., Co., Publishers, and others can be omitted.

For newspapers, journals, magazines, and other periodicals, include the volume and issue number after the title. The volume number is listed first, by itself, in italics. The issue number is in parentheses immediately after it, not italicized. There is no space after the closing parenthesis and before the volume number.

%%Giannoukos, G., Besas, G., Hictour, V., & Georgas, T. (2016). A study on the role of computers in adult education. Educational Research and Reviews , 11 (9), 907-923. https://doi.org/10.5897/ERR2016.2688

After including the publisher information, end this section with a period.

Perseus Books.

Electronic source information:

For online sources, the URL or DOI (Direct Object Identifier) are included at the end of an APA citation.

DOI numbers are often created by publishers for journal articles and other periodical sources. They were created in response to the problem of broken or outdated links and URLs. When a journal article is assigned a DOI number, it is static and will never change. Because of its permanent characteristic, DOIs are the preferred type of electronic information to include in APA citations. When a DOI number is not available, include the source’s URL (see Section 9.34 in the Publication manual ).

For DOIs, include the number in this format:

http://doi.org/xxxx

For URLs, type them in this format:

http:// or https://

Other information about electronic sources:

• If the URL is longer than a line, break it up before a punctuation mark.
• Do not place a period at the end of the citation/URL.
• It is unnecessary to include retrieval dates, unless the source changes often over time (like in a Wikipedia article).
• It is not necessary to include the names of databases

If using the Citation Machine APA citation website autocite features, the online publication information will be automatically replaced by the DOI. The Citation Machine APA template will properly cite your online sources for you.

Make sure you run your completed paper through the Citation Machine Plus smart proofreader, which scans for grammar, spelling, and plagiarism. Whether it’s an adjective , verb , or pronoun out-of-place, our technology helps edits your paper for you!

Annotated bibliographies:

An APA annotated bibliography is a full bibliography that includes a small note for each reference citation. Each note should be short (1-2 paragraphs) and contain a summary or your evaluation about each source. When creating your citations on CitationMachine.net, there is a field at the bottom of each form to add your own annotations.

Follow the publication manual guidelines on paper format and writing style. Let your instructor guide other details about your annotations. Still confused? Read our guide on annotated bibliographies .

These types of projects look different depending on the style you’re using. Use the link at the top of the page to access resources related to the Modern Language Association’s style. Here’s information related to Chicago citation style .

Page formatting

Need help with the design and formatting of your paper? Look no further! This section provides the ins and outs of properly displaying the information in your APA essay.

• Times New Roman, 12-point size.
• Calibri, Arial, or Georgia, 11-point size
• Lucida, Sans Unicode, or Computer Modern, 10-point size
• Indents = Every paragraph should start with an indent.
• Margins = 1 inch around the entire document
• Spacing = Double space everything!

Arrange your pages in this order:

• Page 1 - APA Title Page (see below for information on the title page)
• Page 2 - Abstract (If your professor requests one)
• Page 3 - First page of text
• References begin on their own page. Include the list of references on the page after the text.
• Tables and figures

Keep in mind that the order above is the recommendation for papers being submitted for peer review. If you’re writing an APA style paper for a class, your professor may be more lenient about the requirements. Also, if you’re submitting your paper for a specific journal, check the requirements on the journal’s website. Each journal has different rules and procedures.

Just a little nudge to remind you about the Citation Machine Plus smart proofreader. Whether it’s a conjunction or interjection out of place, a misspelled word, or an out of place citation, we’ll offer suggestions for improvement! Don’t forget to check out our APA citation maker while you’re at it!

Running heads

In older editions of APA, running heads were required for all papers. Since the 7th edition, that’s changed.

• Student paper: No running head
• Professional paper: Include a running head

The running head displays the title of the paper and the page number on all pages of the paper. This header is found on every page of a professional paper (not a student paper), even on the title page (sometimes called an APA cover page) and reference list (taken from Section 2.8 of the Publication manual ).

It's displayed all in capital letters at the top of the page. Across from the running head, along the right margin, is the page number.

• Use the header feature in your word processor. Both Google Docs and Word have these features available.
• Use one for the recommended fonts mentioned under "Page formatting."

Title pages

A title page, sometimes called an APA cover page, graces the cover of an essay or paper. An APA title page should follow rules from Section 2.3 of the official Publication manual and include:

• Page number, which is page 1
• Use title case and bold font
• The title should be under 12 words in length
• The title should be a direct explanation of the focus of the paper. Do not include any unnecessary descriptors such as “An Analysis of…” or “A Study of…”
• Exclude any labels such as Mr., Ms., Dr, PhD...
• Name of the school or institution
• Course number and/or class name
• Name of your instructor, including their preferred honorifics (e.g., PhD, Dr., etc.)
• Paper’s due date
• If this is a professional paper, also include a running head. If this is a student paper, do not include one.

Follow the directions for the running head and page number in the section above. Below the running head, a few lines beneath, and centered in the middle of the page, should be the title. The next line below is the author’s name(s), followed by the name of the school or institution, the class or course name, your instructor’s name, and the paper’s due date.

All components on this page should be written in the same font and size as the rest of your paper. Double space the title, names, name of school or institution, and all other information on the page (except for the running head and page number).

Example - Student Title Page APA:

Example - Professional Title Page APA:

If you’re submitting your paper to a journal for publication, check the journal’s website for exact requirements. Each journal is different and some may request a different type of APA format cover page.

An abstract briefly but thoroughly summarizes dissertation contents. It’s found in the beginning of a professional paper, right after the title page. Abstracts are meant to help readers determine whether to continue reading the entire document. With that in mind, try to craft the lead sentence to entice the reader to continue reading.

Here are a few tips:

• Be factual and keep your opinions out. An abstract should accurately reflect the paper or dissertation and should not involve information or commentary not in the thesis.
• Communicate your main thesis. What was the examined problem or hypothesis? A reader should know this from reading your abstract.
• Keep it brief. Stick to the main points and don’t add unnecessary words or facts. It should not exceed 250 words.
• Consider your paper’s purpose. It’s important to cater your abstract to your paper type and think about what information the target audience for that paper type would want. For example, an empirical article may mention methodology or participant description. A quantitative or qualitative meta-analysis would mention the different variables considered and how information was synthesized.
• Use verbs over noun equivalents, and active voice. Example: “There was research into…” becomes “We researched…”

Formatting guidelines:

• The abstract goes after the title page.
• It should have the same font (size and type) as the rest of the paper.
• It should stick to one page.
• Double-space all page text.
• Center and bold the word “Abstract” at the top of the paper.
• Don’t indent the first line of the abstract body. The body should also be in plain text.
• For the keywords, place it on the line after the abstract and indent the first line (but not subsequent lines). The word “Keywords:” is capitalized, italicized, and followed by a colon. The actual keywords are sentence case and in plan font.
• List each keyword one after the other, and separate them by a comma.
• After the last keyword, no ending punctuation is needed.

Tables & Figures

If your paper includes a lot of numerical information or data, you may want to consider placing it into a table or a figure, rather than typing it all out. A visual figure or simple, organized table filled with numerical data is often easier for readers to digest and comprehend than tons of paragraphs filled with numbers. Chapter 7 of the Publication manual outlines formatting for tables and figures. Let's cover the basics below.

If you’d like to include a table or figure in your paper, here are a few key pieces of information to keep in mind:

• At the end of the paper after the APA reference page
• In the text after it is first mentioned
• The table first mentioned in the text should be titled ‘Table 1.’ The next table mentioned in the text is ‘Table 2,’ and so on. For figures, it would be 'Figure 1,' 'Figure 2,' and so forth.

• Even though every table and figure is numbered, also create a title for each that describes the information it contains. Capitalize all important words in the title.
• For tables, do not use any vertical lines, only use horizontal to break up information and headings.
• Single spacing is acceptable to use in tables and figures. If you prefer double spacing your information, that is okay too.
• Do not include extra information or “fluff.” Keep it simple!
• Do not include the same exact information in the paper. Only include the complete information in one area—the table or the text.
• All tables and figures must be referenced in the text. It is unacceptable to throw a table or figure into the back of the paper without first providing a brief summary or explanation of its relevance.

Publication Manual 6th Edition vs 7th Edition

The 6th edition of the Publication Manual of the American Psychological Association was released in 2009. The current 7th edition came out in the fall of 2019 and was designed to be more student focused, provide more guidance on accessibility, and address changes that have developed over the last 10 years.

Below, we’ve listed what we feel are the most relevant changes related to APA format.

Journals and DOIs

DOI stands for “digital object identifier.” Many journal articles use and have a unique DOI that should be included in a full citation.

When including a DOI in a citation, format it as a URL. Do not label it “DOI.” Articles without DOIs from databases are treated as print works. For example:

6th edition:

%%Gänsicke, B. T., Schreiber, M. R., Toloza, O., Fusillo, N. P. G., Koester, D., & Manser, C. J. (2019). Accretion of a giant planet onto a white dwarf star. Nature, 576 (7785), 61–64. doi: 10.1038/s41586-019-1789-8

7th edition:

%%Gänsicke, B. T., Schreiber, M. R., Toloza, O., Fusillo, N. P. G., Koester, D., & Manser, C. J. (2019). Accretion of a giant planet onto a white dwarf star. Nature, 576 (7785), 61–64. https://doi.org/10.1038/s41586-019-1789-8

Citing Books

There are few new guidelines when you are citing a book. First, the publisher location no longer needs to be indicated.

%%Zack, P. O. (2001). The shoals of time. Bloomington, IN: First Books Library.

%%Zack, P. O. (2001). The shoals of time. First Books Library.

Second, the format of an ebook (e.g., Kindle, etc.) no longer needs to be indicated.

%%Niven, J. (2012). Ada Blackjack: A true story of survival in the Arctic [Kindle].

%%Niven, J. (2012). Ada Blackjack: A true story of survival in the Arctic .

Lastly, books from research databases without DOIs are treated the same as print works.

When using a URL in a citation, you no longer need to include the term “Retrieved from” before URLs (except with retrieval dates). The font should be blue and underlined, or black and not underlined.

6th Edition:

%%Flood, A. (2019, December 6). Britain has closed almost 800 libraries since 2010, figures show. The Guardian . Retrieved from https://www.theguardian.com/books/2019/dec/06/britain-has-closed-almost-800-libraries-since-2010-figures-show

7th Edition:

%%Flood, A. (2019, December 6). Britain has closed almost 800 libraries since 2010, figures show. The Guardian . https://www.theguardian.com/books/2019/dec/06/britain-has-closed-almost-800-libraries-since-2010-figures-show

Within a full APA citation, you may spell out up to 20 author names. For two to 20 authors, include an ampersand (&) before the name of the last author. For sources with 21 or more authors, structure it as follows:

Structure: First 19 authors’ names, . . . Last author’s name.

7th edition example: Washington, G., Adams, J., Jefferson, T., Madison, J., Monroe, J., Adams, J. Q., Jackson, A., Van Buren, M., Harrison, W. H., Tyler, J., Polk, J. K., Taylor, Z., Filmore, M., Pierce, F., Buchanan, J., Lincoln, A., Johnson, A., Grant, U. S., Hayes, R. B., Garfield, . . . Trump, D.

When creating an in-text citation for a source with 3 or more authors, use “et al.” after the first author’s name. This helps abbreviate the mention.

Reference List: Basic Rules

Welcome to the Purdue OWL

This page is brought to you by the OWL at Purdue University. When printing this page, you must include the entire legal notice.

Copyright ©1995-2018 by The Writing Lab & The OWL at Purdue and Purdue University. All rights reserved. This material may not be published, reproduced, broadcast, rewritten, or redistributed without permission. Use of this site constitutes acceptance of our terms and conditions of fair use.

This resourse, revised according to the 7 th  edition APA Publication Manual, offers basic guidelines for formatting the reference list at the end of a standard APA research paper. Most sources follow fairly straightforward rules. However, because sources obtained from academic journals  carry special weight in research writing, these sources are subject to special rules . Thus, this page presents basic guidelines for citing academic journals separate from its "ordinary" basic guidelines. This distinction is made clear below.

Note:  Because the information on this page pertains to virtually all citations, we've highlighted one important difference between APA 6 and APA 7 with an underlined note written in red.  For more information, please consult the   Publication Manual of the American Psychological Association , (7 th  ed.).

Formatting a Reference List

Your reference list should appear at the end of your paper. It provides the information necessary for a reader to locate and retrieve any source you cite in the body of the paper. Each source you cite in the paper must appear in your reference list; likewise, each entry in the reference list must be cited in your text.

Your references should begin on a new page separate from the text of the essay; label this page "References" in bold, centered at the top of the page (do NOT underline or use quotation marks for the title). All text should be double-spaced just like the rest of your essay.

Basic Rules for Most Sources

• All lines after the first line of each entry in your reference list should be indented one-half inch from the left margin. This is called hanging indentation.
• All authors' names should be inverted (i.e., last names should be provided first).
• For example, the reference entry for a source written by Jane Marie Smith would begin with "Smith, J. M."
• If a middle name isn't available, just initialize the author's first name: "Smith, J."
• Give the last name and first/middle initials for all authors of a particular work up to and including 20 authors ( this is a new rule, as APA 6 only required the first six authors ). Separate each author’s initials from the next author in the list with a comma. Use an ampersand (&) before the last author’s name. If there are 21 or more authors, use an ellipsis (but no ampersand) after the 19th author, and then add the final author’s name.
• Reference list entries should be alphabetized by the last name of the first author of each work.
• For multiple articles by the same author, or authors listed in the same order, list the entries in chronological order, from earliest to most recent.
• Note again that the titles of academic journals are subject to special rules. See section below.
• Italicize titles of longer works (e.g., books, edited collections, names of newspapers, and so on).
• Do not italicize, underline, or put quotes around the titles of shorter works such as chapters in books or essays in edited collections.

Basic Rules for Articles in Academic Journals

• Present journal titles in full.
• Italicize journal titles.
• For example, you should use  PhiloSOPHIA  instead of  Philosophia,  or  Past & Present   instead of  Past and Present.
• This distinction is based on the type of source being cited. Academic journal titles have all major words capitalized, while other sources' titles do not.
• Capitalize   the first word of the titles and subtitles of   journal articles , as well as the   first word after a colon or a dash in the title, and   any proper nouns .
• Do not italicize or underline the article title.
• Deep blue: The mysteries of the Marianas Trench.
• Oceanographic Study: A Peer-Reviewed Publication

Please note:  While the APA manual provides examples of how to cite common types of sources, it does not cover all conceivable sources. If you must cite a source that APA does not address, the APA suggests finding an example that is similar to your source and using that format. For more information, see page 282 of the   Publication Manual of the American Psychological Association , 7 th  ed.

When do I use in-text citations?

When should you add in-text citations in your paper .

There are several rules of thumb you can follow to make sure that you are citing your paper correctly in APA 7 format. 

• Think of your paper broken up into paragraphs. When you start a paragraph, the first time you add a sentence that has been paraphrased from a reference -> that's when you need to add an in-text citation. 
• Continue writing your paragraph, you do NOT need to add another in-text citation until: 1) You are paraphrasing from a NEW source, which means you need to cite NEW information OR 2) You need to cite a DIRECT quote, which includes a page number, paragraph number or Section title. 
• Important to remember : You DO NOT need to add an in-text citation after EVERY sentence of your paragraph. 

What do in-text citations look like?

In-text citation styles: .

Let's look at these examples if they were written in text: 

An example with 1 author:

Parenthetical citation:  Following American Psychological Association (APA) style guidelines will help you to cultivate your own unique academic voice as an expert in your field (Forbes, 2020). 

Narrative citation : Forbes (2020) shared that by following American Psychological Association (APA) guidelines, students would learn to find their own voice as experts in the field of nursing. 

An example with 2 authors: 

Parenthetical citation: Research on the use of progressive muscle relaxation for stress reduction has demonstrated the efficacy of the method (Bennett & Miller, 2019). 

Narrative citation: As shared by Bennett and Miller (2019), research on the use of progressive muscle relaxation for stress reduction has demonstrated the efficacy of the method. 

An example with 3 authors: 

Parenthetical citation: Guided imagery has also been shown to reduce stress, length of hospital stay, and symptoms related to medical and psychological conditions (Jones et al., 2020).

Narrative citation: Jones et al. (2020) shared that guided imagery has also been shown to reduce stress, length of hospital stay, and symptoms related to medical and psychological conditions. 

An example with a group/corporate author: 

Parenthetical citation: Dr. Philip G. Rogers, senior vice president at the American Council on Education, was recently elected as the newest chancellor of the university (East Carolina University, 2020). 

Narrative citation: Recently shared on the East Carolina University (2020) website, Dr. Philip G. Rogers, senior vice president at the American Council on Education, was elected as the newest chancellor. 

Tips on Paraphrasing

Paraphrasing is recreating someone else's ideas into your own words & thoughts, without changing the original meaning (gahan, 2020).  .

Here are some best practices when you are paraphrasing: 

• How do I learn to paraphrase? IF you are thoroughly reading and researching articles or book chapters for a paper, you will start to take notes in your own words . Those notes are the beginning of paraphrased information.
• Read the original information, PUT IT AWAY, then rewrite the ideas in your own words . This is hard to do at first, it takes practice, but this is how you start to paraphrase. 
• It's usually better to paraphrase, than to use too many direct quotes. 
• When you start to paraphrase, cite your source. 
• Make sure not to use language that is TOO close to the original, so that you are not committing plagiarism. 
• Use theasaurus.com to help you come up with like/similar phrases if you are struggling. 
• Paraphrasing (vs. using direct quotes) is important because it shows that YOU ACTUALLY UNDERSTAND the information you are reading. 
• Paraphrasing ALLOWS YOUR VOICE to be prevalent in your writing. 
• The best time to use direct quotes is when you need to give an exact definition, provide specific evidence, or if you need to use the original writer's terminology. 
• BEST PRACTICE PER PARAGRAPH: On your 1st paraphrase of a source, CITE IT. There is no need to add another in-text citation until you use a different source, OR, until you use a direct quote.

Citing Direct Quotes

When should i use a direct quote in my paper .

Direct quotes should only be used occasionally: 

• When you need to share an exact definition 
• When you want to provide specific evidence or information that cannot be paraphrased
• When you want to use the original writer's terminology

References provide the information necessary for readers to identify and retrieve each work cited in the text .

Check each reference carefully against the original publication to ensure information is accurate and complete. Accurately prepared references help establish your credibility as a careful researcher and writer.

Consistency in reference formatting allows readers to focus on the content of your reference list, discerning both the types of works you consulted and the important reference elements (who, when, what, and where) with ease. When you present each reference in a consistent fashion, readers do not need to spend time determining how you organized the information. And when searching the literature yourself, you also save time and effort when reading reference lists in the works of others that are written in APA Style.

Citing sources

Tools and resources, a quick guide to working with sources.

Working with sources is an important skill that you’ll need throughout your academic career.

It includes knowing how to find relevant sources, assessing their authority and credibility, and understanding how to integrate sources into your work with proper referencing.

This quick guide will help you get started!

Finding relevant sources

Sources commonly used in academic writing include academic journals, scholarly books, websites, newspapers, and encyclopedias. There are three main places to look for such sources:

• Research databases: Databases can be general or subject-specific. To get started, check out this list of databases by academic discipline . Another good starting point is Google Scholar .
• Your institution’s library: Use your library’s database to narrow down your search using keywords to find relevant articles, books, and newspapers matching your topic.
• Other online resources: Consult popular online sources like websites, blogs, or Wikipedia to find background information. Be sure to carefully evaluate the credibility of those online sources.

When using academic databases or search engines, you can use Boolean operators to refine your results.

Generate APA, MLA, Chicago, and Harvard citations in seconds

Get started

In academic writing, your sources should be credible, up to date, and relevant to your research topic. Useful approaches to evaluating sources include the CRAAP test and lateral reading.

CRAAP is an abbreviation that reminds you of a set of questions to ask yourself when evaluating information.

• Currency: Does the source reflect recent research?
• Relevance: Is the source related to your research topic?
• Authority: Is it a respected publication? Is the author an expert in their field?
• Accuracy: Does the source support its arguments and conclusions with evidence?
• Purpose: What is the author’s intention?

Lateral reading

Lateral reading means comparing your source to other sources. This allows you to:

• Verify evidence
• Contextualize information
• Find potential weaknesses

If a source is using methods or drawing conclusions that are incompatible with other research in its field, it may not be reliable.

Integrating sources into your work

Once you have found information that you want to include in your paper, signal phrases can help you to introduce it. Here are a few examples:

Following the signal phrase, you can choose to quote, paraphrase or summarize the source.

• Quoting : This means including the exact words of another source in your paper. The quoted text must be enclosed in quotation marks or (for longer quotes) presented as a block quote . Quote a source when the meaning is difficult to convey in different words or when you want to analyze the language itself.
• Paraphrasing : This means putting another person’s ideas into your own words. It allows you to integrate sources more smoothly into your text, maintaining a consistent voice. It also shows that you have understood the meaning of the source.
• Summarizing : This means giving an overview of the essential points of a source. Summaries should be much shorter than the original text. You should describe the key points in your own words and not quote from the original text.

Whenever you quote, paraphrase, or summarize a source, you must include a citation crediting the original author.

Citing your sources is important because it:

• Allows you to avoid plagiarism
• Establishes the credentials of your sources
• Backs up your arguments with evidence
• Allows your reader to verify the legitimacy of your conclusions

The most common citation styles are APA, MLA, and Chicago style. Each citation style has specific rules for formatting citations.

How to make ChatGPT provide sources and citations

One of the biggest complaints about ChatGPT is that it provides information that is difficult to check for accuracy. Those complaints exist because ChatGPT doesn't provide the sources, footnotes, or links from which it derived the information in its answers.

While that is true for the GPT-3.5 model, GPT-4 and GPT-4o  provide more citation resources. While GPT-4 is only for paid subscribers, GPT-4o is available to both free and paid subscribers, although free users get fewer citations and less detail than users with a ChatGPT Plus subscription .

Also:  4 things Claude AI can do that ChatGPT can't  

Here's how ChatGPT describes the approach: "GPT-4o in free mode provides basic and essential citations, focusing on quick and concise references to ensure information is traceable. In contrast, GPT-4o in paid mode offers enhanced, detailed, and frequent citations, including multiple sources and contextual annotations to provide comprehensive verification and understanding of the information. This ensures a robust and reliable experience, especially beneficial for users requiring in-depth information and thorough source verification."

Even with the provided citations in GPT-4o, there are ways to improve your results.

1. Write a query and ask ChatGPT

To start, you need to ask ChatGPT something that needs sources or citations. I've found it's better to ask a question with a longer answer, so there's more "meat" for ChatGPT to chew on. 

Also: The best AI chatbots: ChatGPT and other interesting alternatives to try

Keep in mind that ChatGPT can't provide any information after January 2022 for GPT-3.5, April 2023 for GPT-4, and October 2023 for GPT-4o, and requests for information pre-internet (say, for a paper on Ronald Reagan's presidency) will have far fewer available sources.

Here's an example of a prompt I wrote on a topic that I worked on a lot when I was in grad school:

Describe the learning theories of cognitivism, behaviorism, and constructivism

2. Ask ChatGPT to provide sources

This is where a bit of prompt engineering comes in. A good starting point is with this query:

Please provide sources for the previous answer

I've found that this prompt often provides offline sources, books, papers, etc. The problem with offline sources is you can't check their veracity. Still, it's a starting point. A better query is this:

Please provide URL sources

This prompt specifically tells ChatGPT that you want clickable links to sources. You can also tweak this prompt by asking for a specific quantity of sources, although your mileage might vary in terms of how many you get back:

Please provide 10 URL sources

3. Push ChatGPT to give you higher-quality sources

Most large language models  respond well to detail and specificity . So if you're asking for sources, you can push for higher-quality sources. You'll need to specify that you need reliable and accurate sources. While this approach won't necessarily work, it may remind the AI chatbot to give you more useful responses. For example:

Please provide me with reputable sources to support my argument on... (whatever the topic is you're looking at)

You can also tell ChatGPT the kinds of sources you want. If you're looking for scholarly articles, peer-reviewed journals, books, or authoritative websites, mention these preferences explicitly. For example:

Please recommend peer-reviewed journals that discuss... (and here, repeat what you discussed earlier in your conversation)

When dealing with abstract concepts or theories, request that ChatGPT provide a conceptual framework and real-world examples. Here's an example:

Can you describe the principles of Vygotsky's Social Development Theory and provide real-world examples where these principles were applied, including sources for these examples?

This approach gives you a theoretical explanation and practical instances to trace the original sources or case studies.

Also: Two ways you can build custom AI assistants with GPT-4o

Another idea is to use sources that don't have link rot (that is, they're no longer online at the URL that ChatGPT might know). Be careful with this idea, though, because ChatGPT doesn't know about things after January 2022 for GPT-3.5, April 2023 for GPT-4, and October 2023 for GPT-4o. So, while you might be tempted to use a prompt like this:

Please provide me with sources published within the past five years.

Instead, consider using a prompt like this:

Please provide sources published from 2019 through April 2023.

And, as always, don't assume that whatever output ChatGPT gives you is accurate. It's still quite possible the AI will completely fabricate answers, even to the point of making up the names of what seem like academic journals. It's a sometimes helpful tool, but it's also  a fibber .

4. Attempt to verify/validate the provided sources

Keep this golden rule in mind about ChatGPT-provided sources: ChatGPT is more often wrong than right .

Across the many times I've asked ChatGPT for URL sources, roughly half were just plain bad links. Another 25% or more of the links went to topics completely or somewhat unrelated to the one I was trying to source. GPT-4 and GPT-4o are slightly more reliable, but not by much.

Also: How to use ChatGPT: Everything you need to know

For example, I asked for sources on a backgrounder for the phrase "trust but verify,"  generally popularized by US President Ronald Reagan. I got a lot of sources back, but most didn't exist. I got some back that correctly took me to active pages on the Reagan Presidential Library site, but the page topic had nothing to do with the phrase.

I had better luck with my learning theory question from step 1. There, I got back offline texts from people I knew from my studies who had worked on those theories. I also got back URLs. Once again, only about two in 10 worked or were accurate.

Also:  What does GPT stand for? Understanding GPT-3.5, GPT-4, GPT-4o, and more

Don't despair. The idea isn't to expect ChatGPT to provide sources that you can immediately use. If you instead think of ChatGPT as a research assistant, it will give you some great starting places. Use the names of the articles (which may be completely fake or just not accessible) and drop them into Google. That process will give you some interesting search queries that probably lead to interesting material that can legitimately go into your research.

Also, keep in mind that you're not limited to using ChatGPT. Don't forget all the tools available to researchers and students. Do your own web searches. Check with primary sources and subject-matter experts if they're available. If you're in school, you can even ask your friendly neighborhood librarian for help.

Also:  How to use ChatGPT to create an app

Don't forget that there are many excellent traditional sources. For example, Google Scholar and JSTOR  provide access to a wide range of academically acceptable resources you can cite with reasonable confidence.

One final point: if you merely cut and paste ChatGPT sources into your research, you're likely to get stung. Use the AI for clues, not as a way to avoid the real work of research.

How do you put sources in APA format? 

APA style is a citation style that's often required in academic programs. APA stands for American Psychological Association. I've often thought they invented these style rules to get more customers. The definitive starting point for APA style is the Purdue OWL , which provides a wide range of style guidelines.

Also:   GPT-3.5 vs GPT-4: Is ChatGPT Plus worth its subscription fee?

Be careful: online style formatters might not do a complete job, and you may get your work returned by your professor. It pays to do the work yourself -- and be careful doing it.

How can I make ChatGPT provide more reliable sources for its responses?

This is a good question. I have found that sometimes -- sometimes -- if you ask ChatGPT to give you more sources or re-ask for sources, it will give you new listings. If you tell ChatGPT the sources it provided were erroneous, it will sometimes give you better ones. The bot may also apologize and give excuses. Another approach is to re-ask your original question with a different focus or direction, and then ask for sources for the new answer.

Also: How to access, install, and use AI ChatGPT-4 plugins

Once again, my best advice is to avoid treating ChatGPT as a tool that writes for you and more as a writing assistant. Asking for sources to cut and paste a ChatGPT response is pretty much plagiarism. That said, using ChatGPT's responses, and any sources you can tease out, as clues for further research and writing is a legitimate way to use this tool.

Why are ChatGPT sources often so wrong? 

For some links, it's just link rot. Some links may have changed, since many sources are more than three years old. Other sources are of indeterminate age. Since we don't have a full listing of ChatGPT's sources, it's impossible to tell how valid they are or were. 

Also:   How does ChatGPT actually work?  

Since ChatGPT was trained mostly without human supervision , we know that most of its sources weren't vetted and could be wrong, made up, or completely non-existent.

Trust, but verify.

Critically Thinking About “Citing Up”

Considering credibility, familiarity, and patience when citing research..

Posted June 12, 2024 | Reviewed by Davia Sills

• What Is a Career
• Find a career counselor near me
• Newer studies tend not to be referenced as frequently as more established scientific research.
• Credibility, familiarity, and implicit bias all play a role in which research gets cited more often.
• With patience and hard work, researchers can build their reputations as worthy of citation.

I came across an interesting social media post recently in preparation for a professional skills development workshop that I was presenting. The post discussed how academics tend to “cite up” in terms of referencing older, more famous scholars relative to more junior researchers. I thought about this proposition in light of my own citation strategies and knowledge of bibliometrics and concluded that this statement is likely true, but probably not for any explicit bias against junior researchers, as some might posit.

First and foremost, we must consider the purpose of citing research—to represent a source of evidence and indicate that someone didn’t just make up what they’re saying. It’s been established in previous work, and we pay that research kudos to further our argument in context. References are also useful for “ cutting a long story short”—one can cite another’s work that can more fully explain a concept without having to reiterate the whole thing. When I use a reference in my arguments, given that I’m trying to convince the reader of my point, I want to use the most credible source(s) that I can find.

Possible reasons for “citing up”

If Author A is at the apex of credible sources in the field, I’m going to cite them where appropriate. Indeed, if I was reviewing a relevant paper and didn’t see Author A cited, I might be concerned. Of course, one can include multiple citations, but perhaps the reason why more junior or early career researchers are not cited (relative to the Author As out there) is that other researchers may not be as familiar with the early career researchers”—Author Es’—research.

Maybe the citing researcher remembers the research but not the name of the author. Obviously, Author E’s work hasn’t seemed to “stick” yet, maybe because they’re yet to make a bigger impact in the field. Sure, that’s largely the citing researcher’s issue for not having better organized their reading and note-taking, but simply, it’s also an issue of accessibility. If a researcher can’t remember Author E’s name in this context, the credibility of Author A will more than suffice. “Citing up” is not a slight here; it’s just that Author E’s contribution might not be that impactful, accessible, or memorable to a more established researcher. Moreover, I must admit there might be a level of laziness here.

For example, the scenario above is context-dependent. If I can’t remember Author E, that’s fine; I have Author A to cite. However, if Author E is the only appropriate citation, the citing strategy will change. If I know a claim is fundamental to my rationale but I can’t remember where it came from, despite knowing I’ve seen solid evidence for it in the past, I will search for Author E’s paper until I find it (because I have to if there’s no Author A to rely on). This might take time and effort.

I can imagine that some researchers will be reading this and thinking, “Surely, others are reading the new literature and taking notes as they go along or maybe even writing the rationale as they engage the new literature.” Ideally, this should be the case; indeed, it’s a handy way of keeping up-to-date with the literature. However, this does not always happen.

I imagine more established researchers in a field are “familiar enough” with it to write a rationale without having to look up papers every few lines and, instead, are more likely to write what they know. Such is human nature. When they eventually get some free time, they might dedicate a few hours to reading recently published papers. I’m also aware that some researchers are better at this than others. Obviously, this is worrying in the realm of research—perhaps more worrying altogether than the issue of “citing-up.”

With that, what are the chances that a researcher has read every paper in their field? Slim-to-none. Given the exponential increase in the amount of information available to people in the past 25 years and, likewise, the increase in the amount of Ph.D. degrees awarded and research being conducted, being up-to-date with all work in a field just isn’t feasible.

So, maybe “lazy” is unfair in context. Maybe these researchers are indeed reading as much as they can, but because the amount that’s feasible is finite relative to the seemingly endless new research that’s coming out, they might be “pickier” in what they read; for example, prioritizing known and credible researchers in their field. So, there’s a good chance that when only Author A is cited regarding a particular finding, it’s quite possible that it’s because the citing researcher has never even heard of Author E’s paper, let alone read it.

Takeaways for early-career researchers

“New” papers—regardless of when and by whom they’re read, need “sticking power,” and by that, I mean that the research is well-conducted: It is well-written, and interesting food for thought is provided. I compile and read new papers every month—maybe one per session has any sticking power—and that’s not because I’m some kind of research snob; rather, it’s the case that much of it failed some of the criteria above. With that, if the paper had well-conducted research, was well-written, and provided either something novel or some food for thought, then regardless of familiarity, this paper (and its author) would be on my radar for the future. So, just as much as older researchers may be set in their bibliographies or “lazy” referencing, it is most definitely up to younger researchers to publish impactful work.

I completely understand how this is frustrating for early career researchers. I was there once, too. Even though it’s been well over 10 years since I received my Ph.D., I still find myself trying to make the aforementioned impact necessary to be considered one of those “A” researchers in the field. Of course, I get annoyed when I see missed opportunities for other researchers to cite my work. But I’m realistic enough to recognize that maybe they have not come across my work, I have not made a large enough impact for it to be noticed, or the research they did cite was sufficient to make their point. I don’t take it personally, and neither should young researchers. Their time will come, but they must be patient.

Consider the research by Morris, Wooding, and Grant (2011), where it was suggested that it takes approximately 17 years on average for health research implementation from “bench to bedside.” That’s a long time for “research to be realized.” I know citations are different and should be more visible quicker in the land of research, but the same logic applies. Patience—and continued hard work (i.e., to advance one’s research acumen)—are necessary for citation success.

Again, I don’t think that “citing up” is consciously done to slight early career academics; researchers are not conspiring against their junior colleagues—at least, not in my field. If anything, they want to see them and their field flourish. Instead, I think it’s more likely that this issue boils down to an implicit bias (which we all face on a day-to-day basis) toward what we know as familiar, accessible, and credible.
