How to cite in APA when there are multiple authors

This article covers how to cite a reference in APA style (7th ed.) when there are multiple authors. Broadly speaking, in an APA style “the author” refers to the person(s) or group(s) who should be given credit for the work being referenced.

Here’s a run-through of everything this page includes:

In-text citations when there are multiple authors

Reference list entries when there are multiple authors, troubleshooting.

APA 7th ed. uses the author-date citation system for citing references in text. Unless you are citing a source with no author in APA , the structure in parenthetical citations includes placing the author’s last name/surname, followed by a comma, and the publication year in parentheses. In narrative citations, this information is incorporated into the sentence.

Parenthetical citation for one author:

(Author Last Name, Year Published)

(Curtis, 2020)

Narrative citation for one author:

Author Last Name (Year Published)

Curtis (2020)

Two authors

For a work with two authors, include both authors’ last names in every in-text citation, whether narrative or parenthetical. In parenthetical citations, use an ampersand (&) between the authors’ last names.

Parenthetical citation for two authors:

(1st Author & 2nd Author, Year Published)

(Curtis & Williams, 2020)

Narrative citation for two authors:

1st Author & 2nd Author (Year Published)

Curtis & Williams (2020)

Three or more authors

When citing a journal paper in APA with three or more authors, only enter the last name of the first author listed and add “et al.” after it. “Et al.” is Latin for the phrase “and others,” which is why it is used as a substitute for two or more authors’ last names.

Parenthetical citation for three or more authors:

(1st Author et al., Year Published)

(Harris et al., 2020)

Narrative citation for three or more authors:

1st Author et al. (Year Published)

Harris et al. (2020)

Here is a page with more information on when to use “et al.” in APA style .

Group authors

The same guidelines for in-text citations apply when the authors of a source are a distinct group or organization such as a government agency, association, nonprofit organization, business, hospital, task force, or study group. To confirm whether a reference was written by individual author(s) or a group, check the cover or title page.

Hint: for an online resource, the author could be the name of the organization hosting the webpage or website, rather than the name of just one content contributor.

Before using an abbreviated group name as the author of your citation, spell out the abbreviation and define the group one time first in the text. Afterward, use the abbreviation of the group name throughout the rest of the paper.

Group author in-text citation examples:

First parenthetical citation with group abbreviation included: (Association of Jesuit Colleges and Universities [AJCU], 2020)

Subsequent parenthetical citations: (AJCU, 2020)

First narrative citation with group abbreviation included: The Association of Jesuit Colleges and Universities [AJCU] (2020)

Subsequent narrative citations: The AJCU (2020)

Avoiding ambiguity in in-text citations

Sometimes, in-text citations that have three or more authors, some of whom have the same last name, and the same publication year can look like they are the same reference when using the et al. abbreviation. For example, Curtis et al. (2020) could refer to

Curtis, Acres, Thomas, Henderson, and Tyler (2020)

Curtis, Acres, Thomas, Henderson, Maxey, Key, Smith, and Esparza (2020)

To avoid this ambiguity and confusion for the reader, write out as many names as possible for the in-text citation until the references are distinguished, and then add “et. al” to abbreviate the other authors’ names.

Curtis, Acres, Thomas, Henderson, et al. (2020)

Curtis, Acres, Thomas, Henderson, Maxey, et al. (2020)

When only the final author is different, list all of the names in every citation to avoid any confusion.

Curtis, Acres, Thomas, Henderson, and Esparza (2020)

APA has slightly different reference structures for different source types (e.g., book, website, journal article, etc.), but each structure generally includes the following:

Author last name, Author initials. (Date Published). Title. URL or DOI if available .

Need more help with citing a particular source? Find further guidance in this APA citations guide.

One or two authors

For references with one or two authors, cite using the four-part structure.

Two individual authors example:

Smith, J., & Jones, S. (1994). Making a movie star. Behind the Scenes Stories: A Journal of Celebrity Life, 44 (2), 192–200. https://doi.org/l4nds0r

One group author example:

The American Marine Society. (2003). Whale mating patterns in the new millennium. The American Marine Society Magazine , 17-20 . https://fams.gov/article/2003/whale-mating-patterns-in-the-new-millennium

2 – 20 authors

In APA 7th ed., up to 20 authors should be included in a reference list entry. Write out the last name and first initial(s) for each contributor.

2–20 authors example:

Wright, A., Komal, G., Siddharth, D., Boyd, G., Cayson, N., Beverley, K., Travers, K., Begum, A., Redmond, M., Mills, M., Cherry, D., Finley, B., Fox, M., Ferry, F., Almond, B., Howell, E., Gould, T., Berger, B., Bostock, T., Fountain, A. (2020). Styling royalty. London Bridge Press.

21+ authors

For references with more than 20 authors, after listing the 19th author replace any additional author names with an ellipsis ( … ) followed by the final listed author’s last name and first initial(s).

21+ authors example:

Wright, A., Komal, G., Siddharth, D., Boyd, G., Cayson, N., Beverley, K., Travers, K., Begum, A., Redmond, M., Mills, M., Cherry, D., Finley, B., Fox, M., Ferry, F., Almond, B., Howell, E., Gould, T., Berger, B., Bostock, T., . . . Booker, T. (2020). Eating well: Tips from 23 lifestyle authors. Food Magazine. https://foodmag.com/article/2020/tips-from-22-lifestyle-authors

Solution #1: How to order the names of multiple authors in an APA reference

Authors should be cited in the exact order that they are listed by the source, even if they have not been listed alphabetically.

Solution #2: How to cite an article with more than 20 authors in APA style

If an article has more than 20 authors, all authors do not need to be listed in the reference. Instead, name the first 19, then use an ellipsis (…), then add the name of the final author listed. The ellipsis acts as a substitute for all the names between the first 19 and the final authors. No ampersand (&) is needed before the final name.

For example:

Richards, B.A., Lillicrap, T. P., Beaudoin, P., Bengio, Y., Bogacz, R., Christensen, A., Clopath, C.

Costa, R. P., de Berker, A., Ganguli, S., Gillon, C. J., Hafner, D., Kepecs, A., Kriegeskorte,

N., Latham, P., Lindsay, G. W., Miller, K. D., Naud, R., Pack, C. C., … Kording, K. P. (2019). A deep learning framework for neuroscience. Nature Neuroscience ,  22 (11), 1761–1770. https://doi.org/10.1038/s41593-019-0520-2

When making an in-text citation, only write the first author’s last name followed by “et. al.” This applies to both parenthetical and narrative citations.

(Richard et al., 2019)

Richard et al. (2019)

Solution #3: How to cite an article written by an organization in APA style

• Organization as author

When an article is written by an organization, use the typical four-part APA structure (author, date, title, publisher) and cite the organization as the author.

American Nurses Association. (2019). 2018 Annual Report, American Nurse Today, 14 (6), 29-36.

https://www.nursingworld.org/~49d621/globalassets/docs/ana/ana-annual-report-for-

• Organization as author and publisher

If the organization that authored an article is also its publisher , omit the publisher’s name in the citation.

• In-text citation when an organization is an author

Use the organization’s name as the author. For example:

American Nurses Association [ANA] (2019)

If an organization’s name is long, abbreviate it by doing the following:

• First, write the organization’s name in full the first time, followed by the abbreviation in parenthesis.
• After this, you may use the abbreviation without including the complete name.

1 st in-text narrative citation: American Nurses Association [ANA] (2019)

1 st in-text parenthetical citation: (American Nurses Association [ANA] (2019)

After this distinction is made, abbreviations in-text can be used as demonstrated below:

Narrative citations: The ANA (2019)

Parenthetical citations: (ANA, 2019)

To cite a source with multiple authors and an edition number in APA style, you need to know the names of the authors, title of the book, edition number, and publisher. The in-text citation of a book with multiple authors and an edition number is similar to citing a journal or a book reference with multiple authors. An example of a book reference with three authors and an edition number, along with a template, is given below:

In-text citation template and example:

Author Surname et al. (Publication Year)

LeBuffe et al. (2012)

Parenthetical

(Author Surname et al., Publication Year)

(LeBuffe et al., 2012)

Reference list entry template and example:

Author Surname, F. M., Author Surname, F. M., & Author Surname, F. M. (Publication Year). Book title (edition number). Publisher

LeBuffe, P. A., Naglieri, J. A., & Manderth, A. (2012). Devereux early childhood assessment for preschoolers (2nd ed.). Kaplan Early Learning Company.

Use numerals to indicate an edition number. The word “edition” is abbreviated as “ed.” Italicize the book title and follow sentence case for capitalization.

Citing a source that has multiple authors with the same last name and same initials is the same as citing a source with different authors. There is no need to add the initials of the authors in in-text citations as all surnames (although the same) appear in a single source. Examples of a book reference with three authors with the same last name and initials and their templates are given below:

Dunn et al. (2007)

(Dunn et al., 2007)

Author Surname, F. & Author Surname, F. (Publication Year). Book title. Publisher.

Dunn, L. M., Dunn, L. M., & Dunn, L. M. (2007). Peabody picture vocabulary test-IV. American Guidance Service.

About Citing Books

For each type of source in this guide, both the general form and an example will be provided.

The following format will be used:

In-Text Citation (Paraphrase) - entry that appears in the body of your paper when you express the ideas of a researcher or author using your own words.  For more tips on paraphrasing check out The OWL at Purdue .

In-Text Citation (Quotation) - entry that appears in the body of your paper after a direct quote.

References - entry that appears at the end of your paper.

Information on citing and several of the examples were drawn from the Publication Manual of the American Psychological Association (7th ed.).

Book with Three to Five Authors or Editors

The general format below refers to a book with three or more authors.

If you are dealing with a book that has three to five editors instead of authors, you would simply insert the names of the editors into the place where the authors' names are now, followed by "(Eds.)" without the quotation marks (as per the example). The rest of the format would remain the same.

General Format

In-Text Citation (Paraphrase):

(Author Surname et al., Year)

NOTE: The in-text citation for works with three or more authors is shortened to the first author's name followed by et al. and the year.

In-Text Citation (Direct Quote):

(Author Surname et al., Year, page number)

References:

Author Surname, First Initial. Second Initial., Author Surname, First Initial. Second Initial., & Author Surname, First Initial. Second Initial. (Year). Book title: Subtitle . Publisher.

How to Cite a Book in APA Style | Format & Examples

Published on November 14, 2019 by Jack Caulfield . Revised on January 17, 2024.

A book citation in APA Style always includes the author’s name, the publication year, the book title, and the publisher. Use the interactive tool to see examples, or try the free APA Citation Generator to create your citations automatically.

Cite a book in APA Style now:

Table of contents, basic book citation format, ebooks and online books, citing a chapter from an edited book, multivolume books, where to find the information for an apa book citation, frequently asked questions about apa style citations.

The in-text citation for a book includes the author’s last name, the year, and (if relevant) a page number.

In the reference list , start with the author’s last name and initials, followed by the year. The book title is written in sentence case (only capitalize the first word and any proper nouns ). Include any other contributors (e.g. editors and translators) and the edition if specified (e.g. “2nd ed.”).

Prevent plagiarism. Run a free check.

A citation of an ebook (i.e. a book accessed on an e-reader) or a book viewed online (e.g. on Google Books or in PDF form ) includes the DOI where available. If there is no DOI, link to the page where you viewed the book, or where the ebook can be purchased or accessed.

Since ebooks sometimes do not include page numbers, APA recommends using other methods of identifying a specific passage in your in-text citations—for example, a chapter or section title, or a paragraph number.

When citing a particular chapter from a book containing texts by various authors (e.g. a collection of essays), begin the citation with the author of the chapter and mention the book’s editor(s) later in the reference. A page range identifies the chapter’s location in the book.

Some books come in multiple volumes. You may want to cite the entire book if you’ve used multiple volumes, or just a single volume if that was all you used.

Citing a single volume

When citing from one volume of a multivolume book, the format varies slightly depending on whether each volume has a title or just a number.

If the volume has a specific title, this should be written as part of the title in your reference list entry.

Eliot, T. S. (2015). The poems of T. S. Eliot: Vol. 1. Collected and uncollected poems (C. Ricks & J. McCue, Eds.). Faber & Faber.

If the volume is only numbered, not titled, the volume number is not italicized and appears in parentheses after the title.

Dylan, B. (2005). Chronicles (Vol. 1) . Simon & Schuster.

Citing a multivolume book as a whole

When citing the whole book, mention the volumes in parentheses after the title. Individual volume titles are not included even if they do exist.

Eliot, T. S. (2015). The poems of T. S. Eliot (Vols. 1–2) (C. Ricks & J. McCue, Eds.). Faber & Faber.

Scribbr Citation Checker New

The AI-powered Citation Checker helps you avoid common mistakes such as:

• Missing commas and periods
• Incorrect usage of “et al.”
• Ampersands (&) in narrative citations
• Missing reference entries

All the information you need to cite a book can usually be found on the title and copyright pages.

The APA reference list entry for the book above would look like this:

Butler, C. (2002). Postmodernism: A very short introduction . Oxford University Press.

When a book’s chapters are written by different authors, you should cite the specific chapter you are referring to.

When all the chapters are written by the same author (or group of authors), you should usually cite the entire book, but some styles include exceptions to this.

• In APA Style , single-author books should always be cited as a whole, even if you only quote or paraphrase from one chapter.
• In MLA Style , if a single-author book is a collection of stand-alone works (e.g. short stories ), you should cite the individual work.
• In Chicago Style , you may choose to cite a single chapter of a single-author book if you feel it is more appropriate than citing the whole book.

The abbreviation “ et al. ” (meaning “and others”) is used to shorten APA in-text citations with three or more authors . Here’s how it works:

Only include the first author’s last name, followed by “et al.”, a comma and the year of publication, for example (Taylor et al., 2018).

In the 7th edition of the APA manual, no location information is required for publishers. The 6th edition previously required you to include the city and state where the publisher was located, but this is no longer the case.

If you’re citing from an edition other than the first (e.g. a 2nd edition or revised edition), the edition appears in the reference, abbreviated in parentheses after the book’s title (e.g. 2nd ed. or Rev. ed.).

• Include any edition information in parentheses after the title, without italics.
• If the book includes a DOI, include the DOI in the reference after the publisher name.
• Do not include the publisher location.
• If the ebook without a DOI has a stable URL that will resolve for readers, include the URL of the book in the reference (as in the Svendsen and Løber example, which is from the iBog database, where ebooks are referred to as “internetbooks”). Do not include the name of the database in the reference.
• If the ebook is from an academic research database and has no DOI or stable URL, end the book reference after the publisher name. Do not include the name of the database in the reference. The reference in this case is the same as for a print book.

• If the ebook without a DOI has a stable URL that will resolve for readers, include the URL of the book in the reference (as in the Hygum and Pedersen example, which is from the iBog database). Do not include the name of the database in the reference.

3. Republished book, with editor

Watson, J. B., & Rayner, R. (2013). Conditioned emotional reactions: The case of Little Albert (D. Webb, Ed.). CreateSpace Independent Publishing Platform. http://a.co/06Se6Na (Original work published 1920)

• Provide the author of the whole book in the main author element of the reference. Then provide the name of the person who wrote the foreword, introduction, or other new part, in parentheses, after the word “with.” In the example, Byock wrote a new foreword to the book by Kübler-Ross.
• When citing the main book, include only the name of the book author in the in-text citation.
• Parenthetical citation of foreword : Workers in the medical community should “listen to the people who need our help and respond with all the knowledge and skill we can bring to bear” (Kübler-Ross, 1969/2014, foreword by Byock, p. xv).
• Narrative citation of foreword : Byock stated that Kübler-Ross’s (1969/2014) work “challenged the authoritarian decorum and puritanism of the day” (p. xii).

Referencing works with multiple authors

Reference list entries for books, journal articles, or any resource with multiple authors can include up to 20 authors' names before it is necessary to abbreviate.

• For resources with 21+ authors, use the names of the first 19 authors, followed by ellipsis (...) and the name of the final author (i.e., there should be a maximum of 20 authors included in the reference list entry). 

Number of authors to include in text

In-text citations for works with three (3) or more authors can be shortened to the name of the first author and 'et al.' (and page/para. number as usual). 

Important When abbreviating in-text citations with the use of et al., take care to avoid ambiguity.  For example:

(Smith, Jones, & Brown, 2018). (Smith, Jones, Brown, Anderson, Williams, Wilson, & Andrews, 2018).

Both citations above refer to  different works  published in the same year. Both could be shortened to simply (Smith et al., 2018), thereby creating confusion as to which work is being cited. To avoid ambiguity,  the names of as many authors as necessary to distinguish the sources should be used in each citation before abbreviation with et al. For example :

(Smith, Jones, & Brown, 2018). (Smith, Jones, Brown, Anderson et al., 2018).

Referencing a book with two authors

The example below shows how to reference a book with two authors and indicates the different elements needed.
