Ordering works on the APA reference page

Published on November 4, 2020 by Raimo Streefkerk . Revised on January 17, 2024.

An APA Style reference page is ordered alphabetically by the first element in the reference entry , usually the first author’s last name.

• Smith, B. H. precedes Thompson, A. G.

In more complex situations, this basic guideline may not be enough. That’s probably why you’re here, right? Luckily, APA created more detailed guidelines that are outlined in this article.

Table of contents

Multiple works with the same first author, different authors with the same last name, no author (source title), same author, same date, nothing precedes something, apostrophes, hyphens, parentheses, and brackets, m’, mc, and mac, suffixes (sr., jr., i, ii, iii), frequently asked questions, single-author works.

If the works have just one author, order them based on the publication date, listing the oldest source first. Works with no date come before works with a date. Works that are “In press” come last.

• Warren, K. J. (n.d.)
• Warren, K. J. (2018)
• Warren, K. J. (in press)

Multiple-author works

If the first author is the same, but subsequent authors are different, order the references based on the second author’s last name. If the second author is the same, then order on the third author, and so on. One-author works come before multiple-author works.

• Palmer, T., & Hunt, S.
• Palmer, T., Hunt, S., & Robertson, H.

Get started!

Order works from different authors with the same last name based on their initials.

• Theel, M. precedes Theel, P. S.

When the author of a work is unknown, the source title is moved to the author position. In this case, the reference is ordered based on the title. Disregard “A”, “An”, and “The” at the beginning of the title. If the title starts with a numeral, alphabetize it as though it were spelled out.

• How social media influences mental health (ordered on the H of “How”)
• The impact of smartphones on creativity (ordered on the I of “Impact”)
• 10 ways to increase your productivity (ordered on the T of “Ten”)

Works with the same author and date are distinguished with a lowercase letter after the publication year. This letter appears in the APA in-text citation and the reference entry . Order works by that lowercase letter.

• Browning, H. (2020a) precedes Browning, H. (2020b)

Prevent plagiarism. Run a free check.

Shorter names precede longer names with which they share all their letters.

• Camp H. G. precedes Campbell A. T.

Disregard apostrophes and hyphens in two-word names, and disregard anything in parentheses (e.g., contributor roles) or brackets (e.g., usernames).

• O’Connor, G. precedes Oetman, H.
• Bloom, S.-J. precedes Bloom, S. P.

Order prefixes such as M’, Mc, and Mac as spelled, not as sounded out.

• MacArthur, B. precedes McCombes, S.
• MacNeil, J. precedes M’Carthy, P.

Works authored by people with the same first and last name, but with a suffix such as Jr., Sr. or I, II, III, are ordered chronologically, oldest first.

• Burrows, L., Sr. precedes Burrows, L., Jr.
• Andrews, K. P., II precedes Andrews, K. P., III

If the author of a work is unknown, order the reference by its title. Disregard the words “A”, “An”, and “The” at the beginning of the title.

• The privacy concerns around social media
• Teens, social media, and privacy

Order numerals as though they were spelled out:

• “20 tips to relax” is ordered on the “T” of “Twenty”.
• “100 cities you should visit” is ordered on the “O” of “One hundred”.

Popular word processors like Microsoft Word and Google Docs can order lists in alphabetical order, but they don’t follow the APA Style alphabetization guidelines .

How to Format an APA Reference Page

In APA, the “Works Cited” page is referred to as a “Reference List” or “Reference Page.” “Bibliography” also may be used interchangeably, even though there are some differences between the two.

If you are at the point in your article or research paper where you are looking up APA bibliography format, then congratulations! That means you’re almost done.

In this guide, you will learn how to successfully finish a paper by creating a properly formatted APA bibliography. More specifically, you will learn how to create a reference page . The guidelines presented here come from the 7 th edition of the APA’s Publication Manual .

A note on APA reference page style: In this guide, “bibliography” and “references” may be used interchangeably, even though there are some differences between the two. The most important thing is to use the label “References” when writing your paper since APA style recommends including a reference page.

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

Difference between an APA bibliography and a reference page

What about annotated bibliographies, understanding apa reference page format, apa reference page formatting: alphabetizing by surname, q: what should not be on an apa reference page.

The difference between a bibliography and a reference page is a matter of scope. A bibliography usually includes all materials and sources that were used to write the paper. A reference page, on the other hand, only includes entries for works that were specifically cited in the text of the paper.

There are some cases in which a professor or journal might request an annotated bibliography . An annotated bibliography is basically a reference page that includes your comments and insights on each source.

An annotated bibliography can be a document all on its own, or part of a bigger document. That means creating an annotated bibliography by itself could be an assignment, or you may have to include one as part of your research paper, journal submission, or other project.

If you do need to add an APA annotated bibliography , it goes after the reference page on its own page, inside the appendices.

A properly formatted APA reference page begins on a new page, after the end of the text. It comes before any figures, tables, maps, or appendices. It’s double-spaced and features what’s called a hanging indent , where the first line of each reference is not indented, and the second line of each reference is indented 0.5 inches. The reference page is also labeled with a bold, center-justified, and capitalized “References.”

To summarize, the reference page should be:

• Placed on its own page, after the text but before any tables, figures, or appendices.
• In the same font as the rest of the paper.
• Double-spaced the whole way through (including individual references).
• Formatted with hanging indents (each line after the first line of every entry indented 0.5 inches).
• Labeled with a bold, center-justified, and capitalized “References.”

Note: You can use the paragraph function of your word processing program to apply the hanging indent.

Q: What font am I supposed to use for the reference page or bibliography?

The APA reference page/bibliography should be in the same font as the rest of your paper. However, APA Style does not actually call for one specific font. According to Section 2.19 of the Publication Manual , the main requirement is to choose a font that is readable and accessible to all users. Some of the recommended font options for APA style include:

• Sans serif fonts: Calibri (11pt), Arial (11pt), or Lucida (10pt).
• Serif fonts: Times New Roman (12pt), Georgia (11pt), or Normal/Computer Modern (10pt).

Q: What are the margins supposed to be for the reference page or bibliography?

Aside from the 0.5 inch hanging indent on the second line of each reference entry, you do not need to modify the margins of the reference page or bibliography. These should be the same as the rest of your paper, which according to APA is 1-inch margins on all sides of the page. This is the default margin setting for most computer word processors, so you probably won’t have to change anything.

Q: What information goes into an APA style reference page or bibliography?

An APA style reference page should include full citations for all the sources that were cited in your paper. This includes sources that were summarized, paraphrased, and directly quoted. Essentially, if you included an in-text citation in your paper, that source should also appear in your reference list. The reference list is organized in alphabetical order by author.

The formatting for reference list citations varies depending on the kind of source and the available information. But for most sources, your reference list entry will include the following:

• The last name(s) and initials of the author(s).
• The date the source was published (shown in parentheses).
• The title of the source in sentence case. The title should be in italics if the source stands on its own (like a book, webpage, or movie).
• The name of the periodical, database, or website if the source is an article from a magazine, journal, newspaper, etc. Names of periodicals are usually italicized; names of databases and websites usually are not.
• The publisher of the source and/or the URL where the source can be found.

Here are a few templates and examples for how common sources should be formatted in an APA style reference list. If your source is not found here, there is also a guide highlighting different APA citation examples .

Citing a Book

Author’s last name, Author’s first initial. Author’s middle initial. (Year of publication). Title of work . Publisher.

James, Henry. (2009). The ambassadors . Serenity Publishers.

Citing a Journal

Author’s last name, Author’s first initial. Author’s middle initial. (Year, Month Date published). Article title. Journal Name , Volume(Issue), page number(s). https://doi.org/ or URL (if available)

Jacoby, W. G. (1994). Public attitudes toward government spending. American Journal of Political Science , 38(2), 336-361. https://doi.org/10.2307/2111407

Citing a Website

Author’s last name, Author’s first initial. Author’s middle initial. (Year, Month Date published). Article title or page title . Site Name. URL

Limer, E. (2013, October 1). Heck yes! The first free wireless plan is finally here . Gizmodo. https://gizmodo.com/heck-yes-the-first-free-wireless-plan-is-finally-here

Next, let’s take a look at a real example of a properly formatted APA reference page to see how these pieces come together.

APA reference page example

Creating an APA reference page is actually a lot easier than creating a bibliography with other style guides. In fact, as long as you are aware of the formatting rules, the reference page practically writes itself as you go.

Below is an example reference page that follows the guidelines detailed above. EasyBib also has a guide featuring a complete APA style sample paper , including the reference page.

All APA citations included in the reference page should be ordered alphabetically, using the first word of the reference entry. In most cases, this is the author’s surname (or the surname of the author listed first, when dealing with citations for sources with multiple authors ). However, there are times when a reference entry might begin with a different element.

Creating an alphabetized reference page or bibliography might seem like a simple task. But when you start dealing with multiple authors and similar last names, it can actually get a little tricky. Fortunately, there are a few basic rules that can keep you on track.

The “nothing precedes something” rule

When the surnames of two or more authors begin with the same letters, the “nothing precedes something” rule is how to figure it out. Here is an example of how it works.

Imagine your reference page includes the authors Berg, M.S. and Bergman, H.D. The first four letters of each author are the same. The fifth letters are M and H respectively. Since H comes before M in the alphabet, you might assume that Bergman, H.D. should be listed first.

APA Style requires that “nothing precede something,” which means that Berg will appear before Bergman. Similarly, a James would automatically appear before a Jameson, and a Michaels before a Michaelson.

Disregard spaces and punctuation marks

If a surname has a hyphen, apostrophe, or other punctuation mark, it can be ignored for alphabetization purposes. Similarly, anything that appears inside of parentheses or brackets should be disregarded.

Ordering multiple works by the same author

It is not uncommon for a research paper to reference multiple books by the same author. If you have more than one reference entry by the same person, then the entries should be listed chronologically by year of publication.

If a reference entry has no year of publication available, then it should precede any entries that do have a date. Here’s an example of a properly alphabetized order for multiple entries from the same author:

Guzman, M.B. (n.d.).

Guzman, M.B. (2016).

Guzman, M.B. (2017).

Guzman, M.B. (2019).

Guzman, M.B. (in press).

“In press” papers do not yet have a year of publication associated with them. All “in press” sources are listed last, like the one shown above.

Ordering works with the same author and same date

If the same author has multiple entries with the same year of publication, you need to differentiate them with lowercase letters. Otherwise, the in-text citations in your paper will correspond to more than one reference page entry.

Same author and same year of publication

Here’s a look at how to use lowercase letters to differentiate between entries with the same author and same year of publication:

Guzman, M.B. (2020a).

Guzman, M.B. (2020b).

Guzman, M.B. (2020c).

These lowercase letters are assigned to make the in-text citations more specific. However, it does not change the fact that their year of publication is the same. If no month or day is available for any of the sources, then they should be ordered alphabetically using the title of the work.

When alphabetizing by title, ignore the words “A,” “An,”,and “The” if they’re the first word of the title.

Same author and same year of publication, with more specific dates

If more specific dates are provided, such as a month or day, then it becomes possible to order these entries chronologically.

Guzman, M.B. (2020b, April 2).

Guzman, M.B. (2020c, October 15).

Ordering authors with the same surname but different initials

Authors who share the same surname but have different first or middle names can be alphabetized by their first initial or second initial.

Guzman, R.L. (2015).

Ordering works with no listed author, or an anonymous author

If you have reference entries with no listed author, the first thing to double-check is whether or not there was a group author instead. Group authors can be businesses, task forces, nonprofit organizations, government agencies, etc.

If there is no individual author listed, then have another look at the source. If it is published on a government agency website, for instance, there is a good chance that the agency was the author of the work, and should be listed as such in the reference entry. You can read more about how to handle group authors in Section 9.11 of the Publication Manual .

What if the work is actually authored by “Anonymous”?

If the work you’re referencing actually has the word “Anonymous” listed as the author, then you can list it as the author and alphabetize it as if it were a real name. But this is only if the work is actually signed “Anonymous.”

What if there is no listed author and it’s definitely not a group author?

If you have confirmed that there is no individual or group author for the work, then you can use the work’s title as the author element in the reference entry. In any case where you’re using the work’s title to alphabetize, you should skip the words “A,” “An,” and “The.”

An APA reference page should not contain any of the following:

• The content of your paper (the reference page should start on its own page after the end of your paper).
• Entries for works for further reading or background information or entries for an epigraph from a famous person (the reference page should only include works that are referenced or quoted in your paper as part of your argument).
• Entries for personal communications such as emails, phone calls, text messages, etc. (since the reader would not be able to access them).
• Entries for whole websites, periodicals, etc. (If needed, the names of these can be mentioned within the body of your paper instead.)
• Entries for quotations from research participants (since they are part of your original research, they do not need to be included).

The following rules will help you identify when to use DOIs and when to use URLs in references:

• Use a DOI wherever available, be it a print version or online version.
• For a print publication that does not have a DOI, do not add a DOI or URL (even if a URL is available).
• For an online publication, if both a DOI and URL are given, include only the DOI.
• For online publications that only have a URL (and no DOI), follow the below recommendations:
• Add a URL in the reference list entry for publications from websites (other than databases). Double check that the URL will work for readers.
• For publications from most academic research databases, which are easily accessible, do not include a URL or database information in the reference. In this case, the reference will be the same as the print version.
• For publications from databases that publish limited/proprietary work that would only be available in that database, include the database name and the URL. If the URL would require a login, include the URL for the database home page or login page instead of the URL for the work.
• If a URL will not work for the reader or is no longer accessible, follow the guidance for citing works with no source.

To format your APA references list, follow these recommendations:

• Begin the references on a new page. This page should be placed at the end of the paper.
• All sides of the paper should have a 1-inch margin.
• Set the heading as “References” in bold text and center it.
• Arrange the reference entries alphabetically according to the first item within the entries (usually the author surname or title).
•  Add a hanging indent of 0.5 inches (i.e., indent any line after the first line of a reference list entry).

See above for a visual example of a reference page and additional examples.

Special Cases

Multiple entries with the same author(s) are arranged by publication year. Entries with no dates first, then in chronological order. If the year published is also the same, a letter is added to the year and the entries are arranged alphabetically (after arrangement by year).

• Robin, M. T. (n.d.)
• Robin, M. T. (1987)
• Robin, M. T. (1989a)
• Robin, M. T. (1989b)

Single-author source and multi-author source that share one author. One-author entries are listed first even if the multi-author entries were published earlier.

• Dave, S. P., Jr. (2006)
• Dave, S. P., Jr., & Glyn, T. L. (2005)

For references with multiple authors that have the same first author but different subsequent authors, alphabetize the entries by the last name of the second author (or third if the first two authors are the same).

An APA reference page is a list of sources you've mentioned or used throughout your writing, formatted in the APA style, and should be included at the very end of your paper. The details of each source must be displayed in a specific way, depending on the type of the source ( websites , books , journals , or other sources ).

A Reference Page must:

• Have the title of ' Reference List ' at the very top
• Show every source you've directly referenced in your paper, or taken data from to help you write your paper.
• List all sources in alphabetical order by the author's last name. For example, a source by Albert Einstein would be higher in the list than a source by Elon Musk, as the E in Einstein comes before the M in Musk alphabetically.
• Use a hanging indent for each entry after the first line, indented by half an inch from the left margin.
• Retain all original punctuation and formatting for any names and titles of the sources.

Our APA citation generator can do all this for you automatically. To start, just search for one of the sources used in your writing using the tool below. Alternatively we have also explained how to format specific sources on the next page.

Notes on the layout for your reference list:

Layout of page:

• The reference list starts on a new page, after your assignment and before any appendices. Place the word "References", centered, in bold, at the top of the page. APA does not require other formatting for the title of your reference page (like underlining), but check with your lecturer.
• Each entry in the reference list has a hanging indent , so that the first line of the entry is flush with the left margin, but all other lines are indented (this is the opposite of the paragraph structure in the body of your essay). Tip: You can do this easily by selecting your references, and pressing Ctrl + T on a PC, or Command (⌘) + T on a Mac. (For Word Online, see the instructions for creating a hanging indent here: https://libanswers.jcu.edu.au/faq/266638 ).

Order of references:

• For APA the reference list is arranged in alphabetical order of authors' surnames.
• Arrange by first author's name, then by second author if you have the same first author, etc. ( check the page on Authors for how to lay out the reference if you have more than one author ).
• If a reference has no author , list it alphabetically according to the title. Ignore the words 'A', 'An' and 'The' at the beginning of a corporate author or title for deciding where it fits alphabetically.
• N.B. A year without a date is considered to be "older" than a year with a date ("nothing comes before something"), so 2018 will go before 2018, September - and a month without a day will go before a month with a day, so 2018, September will go before 2018, September 12. Please note that the year only is required in-text, so you will need to follow the advice below whenever you have multiple citations in the same year.
• N.B. If you have a full date, only use the title to order the references if the date is identical. Always use 'a', 'b', etc after the year, if more than one work has been published by the same author in the same year, as this is used in the in-text referencing, e.g. (2019a, April 12), (2019b, March 23). For example:

Queensland Health. (2017a, April 9). Managing your asthma symptoms . https://www.health.qld.gov.au/news-alerts/news/managing-asthma-symptoms

Queensland Health. (2017b, August 23). Five things you might not know about asthma . https://www.health.qld.gov.au/news-alerts/news/5-things-you-might-not-know-about-asthma

Format of titles:

• APA uses sentence case for all titles except for journal titles.
• Begin each title and subtitle with a capital letter, but only names should be capitalised for all titles other than journal titles.

Below is an example of a reference list formatted in APA style.  Mouse over the references to find more information about writing a reference list.

This list has been single spaced for this guide, but you will probably be asked to double-space your assignment, and that includes the reference list.

Note: the DOIs and URLs in the reference list above should be hyperlinked to the appropriate page, but the code for hyperlinking and the code for mouseover text was not compatible. In your reference list, make sure your DOIs and URLs are hyperlinked to the relevant page.

Elements of a Reference

A reference entry generally has four elements:

• Author: Who is responsible for this work?
• Date: When was this work published?
• Title: What is this work called?
• Source: Where can I retrieve this work?

Where to Find Information for a Journal Article

Typically, the information needed for a reference is found at the beginning of a journal article. See the example below with labeled elements.

Reference List Formatting

Use these guidelines to properly format your reference list in APA Style:

• Begin the reference list on a new page after the text.
• Place the section label "References" in bold at the top of the page, centered.
• Order the reference list entries alphabetically.
• Double-space the entire reference list (both within and between entries).
• Apply a hanging indent of 0.5 in. to each reference list entry, meaning that the first line of the reference is flush left and subsequent lines are indented 0.5 in. from the left margin.

Reference List Order

Works are listed in alphabetical order in the reference list, by the first word of the reference list entry.

• Arrange entries in alphabetical order by the surname of the first author followed by the initials of the author's given name(s).
• When alphabetizing names, disregard any spaces or punctuation marks in two-word surnames. Also disregard anything in parentheses or square brackets.

If multiple works are by the same first author,

• One-author entries should be arranged by year of publication, the earliest first. References with no date precede references with dates.      Ling, C. (n.d.).      Ling, C. (2016).      Ling, C. (2019a).      Ling, C. (2019b).  
• One-author entries should precede multiple-author entries beginning with the same first author, even if the multiple-author work is published earlier.      Dorsey, A. E. (2019).      Dorsey, A. E. & Kirkwood, M. (2015).  
• Multiple-author entries in which all authors appear in the same order should be arranged by year of publication.      Hanks, A., & Hudson, C. S. (2017).      Hanks, A., & Hudson, C. S. (2018).  
• Multiple-author entries with the same first author and different subsequent authors should be arranged alphabetically by the surname of the second author or, if the second author is the same, the surname of the third author, and so forth.

Other rules of alphabetizing include:

• When alphabetizing by title, disregard the world "A," "An," and "The."
• If a reference entry begins with "Anonymous," alphabetize it as if it were a true name.
• If first authors of different works have the same surname and different initials, arrange alphabetically by first initial(s).
• Alphabetize numerals as though they were spelled out.

Formatting Rules

Keep in mind the following guidelines:

• References cited in text must appear in the reference list and vice versa (exception for personal communication which is not included in a Reference list).
• Make sure that all citation information (names of authors, titles, volume and issue numbers, edition number, page numbers, publisher name and location information) is correct.
• All authors' names should be inverted (i.e., last names should be provided first).
• Authors' first and middle names should be written as initials
• When listing titles, the only words you should capitalize are the first word of the title, the first word of the subtitle (if there is one), and proper nouns (Oregon, Eleanor Roosevelt). 
• The following should be italicized:  Titles of books, ebooks, newspapers, journals, magazines, movies, dissertation/thesis, films, videos, television series, podcasts, YouTube videos, artwork, maps, music albums and unpublished manuscripts.  Additionally, volumes of journals are also italicized.
• Reference lists must be double-spaced , with a hanging indent.

Order of References in Reference List

• Alphabetize letter by letter
• Alphabetize prefixes such as Mc and Mac literally
• Alphabetize surnames that contain articles and prepositions (de, la, du, von, etc.) according to the rules of the language of origin
• Alphabetize items with numerals as if the numerals were spelled out
• Alphabetize group authors such as associations or agencies by the first significant word of the name, and use the full official name, not an acronym
• If the author is designated as Anonymous, then the entry is alphabetized as if Anonymous were a true name
• If there is no author, the entry is alphabetized by the first significant word in the title

• Use pp. for book chapter  page numbers but not for journal articles.
• Arrange works with the same author(s) and same year alphabetically by title in the reference list. This then determines which references uses a, b, c etc.
• Add the relevant letter after the year (which is also used for corresponding in-text references). The first reference listed in the reference list uses "a", second uses "b" etc.

The APA reference page (also called the reference list) is the final page of your paper where all sources you cited in the main text are listed.

It should include the full details of all sources you cited in the main text, arranged A-Z alphabetically by author’s surname.

Everything cited in the text must appear in the reference list, and everything on your reference page must be something you have referred to in the text. Make sure you don”t have anything in one place that isn’t in the other.

Reference Page vs. Bibliography

A reference list includes all works that have been cited in the assignment. A bibliography is a detailed list of references cited in your work, plus the background readings or other material you may have read, but not cited.

Note : This page reflects the latest version of the APA Publication Manual (i.e., APA 7), which released in October 2019.

Reference Page: Basic Rules

List references on a new page. Type “References” as page heading, written in boldface, at the top center of the page. Use double spacing. Reference list entries should be alphabetized by the last name of the first author of each work. For multiple articles by the same author, list the entries in chronological order, from earliest to most recent. Indent second and subsequent lines of each entry using a hanging indent of 5-7 spaces (by pressing Ctrl + T on a PC, or Command (⌘) + T on a Mac). All references in APA end with a full stop except when the reference ends with a URL or a DOI.

Reference List: Author/Authors

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.

Note:  This page reflects the latest version of the APA Publication Manual (i.e., APA 7), which released in October 2019. The equivalent resource for the older APA 6 style  can be found here .

The following rules for handling works by a single author or multiple authors apply to all APA-style references in your reference list, regardless of the type of work (book, article, electronic resource, etc.).

Note:  Because the information on this page pertains to virtually all citations, we've highlighted a few important differences between APA 6 and APA 7 with underlined notes written in red.

Single Author

Last name first, followed by author initials.

Ahmed, S. (2012).  On being included: Racism and diversity in institutional life . Duke University Press.

Two Authors

List by their last names and initials. Separate author names with a comma. Use the ampersand instead of "and."

Soto, C. J., & John, O. P. (2017). The next big five inventory (BFI-2): Developing and assessing a hierarchical model with 15 facets to enhance bandwidth, fidelity, and predictive power. Journal of Personality and Social Psychology , 113 (1), 117-143. http://dx.doi.org/10.1037/pspp0000096

Three to Twenty Authors

List by last names and initials; commas separate author names, while the last author name is preceded again by ampersand.  This is a departure from APA 6, which only required listing the first six authors before an ellipsis and the final author's name.

Nguyen, T., Carnevale, J. J., Scholer, A. A., Miele, D. B., & Fujita, K. (2019). Metamotivational knowledge of the role of high-level and low-level construal in goal-relevant task performance. Journal of Personality and Social Psychology, 117 (5), 879-899. http://dx.doi.org/10.1037/pspa0000166

More Than Twenty Authors

List by last names and initials; commas separate author names. After the first 19 authors’ names, use an ellipsis in place of the remaining author names. Then, end with the final author's name (do not place an ampersand before it). There should be no more than twenty names in the citation in total.

Pegion, K., Kirtman, B. P., Becker, E., Collins, D. C., LaJoie, E., Burgman, R., Bell, R., DelSole, R., Min, D., Zhu, Y., Li, W., Sinsky, E., Guan, H., Gottschalck, J., Metzger, E. J., Barton, N. P., Achuthavarier, D., Marshak, J., Koster, R., . . .  Kim, H. (2019). The subseasonal experiment (SubX): A multimodel subseasonal prediction experiment. Bulletin of the American Meteorological Society , 100 (10), 2043-2061. https://doi.org/10.1175/BAMS-D-18-0270.1

Group Author

Group authors can include corporations, government agencies, organizations, etc; and a group may publish in coordination with individuals. Here, you simply treat the publishing organization the same way you'd treat the author's name and format the rest of the citation as normal. Be sure to give the full name of the group author in your reference list, although abbreviations may be used in your text.

Entries in reference works (  e.g. dictionaries, thesauruses, and encyclopedias) without credited authors are also considered works with group authors.

Merriam-Webster. (2008). Braggadocio. In Merriam-Webster’s Advanced Learner’s English Dictionary . Merriam-Webster.

When a work has multiple layers of group authorship (e.g. The Office of the Historian, which is a part of the Department of State, publishes something), list the most specific agency as the author and the parent agency as the publisher.

Bureau of International Organization Affairs. (2018). U.S. contributions to international organizations, 2017 [Annual report]. U.S. Department of State. https://www.state.gov/u-s-contributions-to-international-organizations/

Unknown Author

When the work does not have an author move the title of the work to the beginning of the references and follow with the date of publication. Only use “Anonymous ” if the author is the work is signed “Anonymous.” This is a new addition to APA 7.

Merriam-Webster's collegiate dictionary (11th ed.). (2003). Merriam-Webster.

NOTE : When your essay includes parenthetical citations of sources with no author named, use a shortened version of the source's title instead of an author's name. Use quotation marks and italics as appropriate. For example, parenthetical citations of the source above would appear as follows: ( Merriam-Webster's , 2003).

Two or More Works by the Same Author

Use the author's name for all entries and list the entries by the year (earliest comes first). List references with no dates before references with dates.

Urcuioli, P. J. (n.d.).

Urcuioli, P. J. (2011). 

Urcuioli, P. J.  (2015).

When an author appears both as a sole author and, in another citation, as the first author of a group, list the one-author entries first.

Agnew, C. R. (Ed.). (2014). Social influences on romantic relationships: Beyond the dyad . Cambridge University Press.

Agnew, C. R., & South, S. C. (Eds.). (2014). Interpersonal relationships and health: Social and clinical psychological mechanisms. Oxford University Press.

References that have the same first author and different second and/or third authors are arranged alphabetically by the last name of the second author, or the last name of the third if the first and second authors are the same.

Arriaga, X. B., Capezza, N. M., Reed, J. T., Wesselman, E. D., & Williams, K. D. (2014). With partners like you, who needs strangers?: Ostracism involving a romantic partner. Personal Relationships, 21(4) , 557-569.

Arriaga, X. B., Kumashiro, M., Finkel, E. J., VanderDrift, L. E., & Luchies, L. B. (2014). Filling the void: Bolstering attachment security in committed relationships. Social Psychological and Personality Science, 5 (4), 398-405.

Two or More Works by the Same Author in the Same Year

If you are using more than one reference by the same author—or the same group of authors listed in the same order—published in the same year, first check to see if they have more specific dates ( this recommendation is new to APA 7) . Works with only a year should be listed before those with a more specific date. List specific dates chronologically.  If two works have the same publication date, organize them in the reference list alphabetically by the title of the article or chapter. If references with the same date are identified as parts of a series (e.g. Part 1 and Part 2), list them in order of their place in the series. Then assign letter suffixes to the year. Refer to these sources in your essay as they appear in your reference list, e.g.: "Berndt (2004a) makes similar claims..."

Berndt, T. J. (2004a).  Children’s friendships: Shifts over a half-century in perspectives on their development and their effects.  Merrill Palmer Quarterly, 50 (3) , 206-223.

Berndt, T. J. (2004b).  Friendship and three A’s (aggression, adjustment, and attachment).  Journal of Experimental Child Psychology, 88 (1) , 1-4.

Introductions, Prefaces, Forewords, and Afterwords

Cite the publishing information about a book as usual, but cite Introduction, Preface, Foreword, or Afterword (whatever title is applicable) as the chapter of the book.

In a nutshell: APA reference order

• It is crucial to adhere to specific ordering guidelines when creating APA style references.
• In general, papers should be organized alphabetically by the first author’s surname.
• When citing multiple works by the same author, we follow the chronological order.
• When dealing with authors who share the same name, initials, and work titles, it is essential to find ways to differentiate between them in the APA reference order.
• If the author of a work is unknown, the reference should be listed in alphabetical order according to its title.

Definition: APA reference order

The APA reference order pertains to the organized arrangement of cited sources in a paper or article, following APA style guidelines. This system aids in the easy accessibility and navigation of cited references for readers, ultimately improving the readability and credibility of the written work.

Ordering works on the APA reference page

The following sections will explain the format for reference entries and in-text citations in APA style, including how to cite sources with a single author, multiple authors, and no authors.

General format for reference entry and in-text citations

Single author, multiple authors, and no author, single author, same author, different works, multiple authors, same surname.

In APA style, references are typically listed in alphabetical order by the author’s surname.

• Smith, J. (2018). The Science of Climate Change. Penguin Publishing.

When you have multiple works by the same author, order the entries chronologically by year of publication, from oldest to most recent. If there are several works in the same year, append a, b, c, etc. to the year.

• Smith, J. (2020a). Global Warming: A Modern Crisis. Harper Collins.
• Smith, j (2020b), Title of the second book in 2020. XYZ Publishing.

If you have multiple authors with the same surname, include the initials in the citation to avoid confusion.

• Smith, R. (2020). Global Warming: A Modern Crisis. Harper Collins.

When citing works from different authors who share the same last name, include the first initials in the in-text citations.

• Smith (2020) and M. Smith (2021) have different views on the subject.

If no author is listed for a source, the reference should be listed by the title of the work. In this case, ignore leading articles (A, An, The) when alphabetizing.

• The Science of Climate Change. (2018). Penguin Publishing.

APA reference order: Easing the process of ordering references

Using reference management software can simplify the process of organizing references in APA reference order. Tools like

• and Mendeley

automatically format the citations and the reference list in the required style, including APA.

How are multiple works by the same author published in the same year ordered in APA reference order?

They are distinguished by adding lowercase letters (a, b, c, etc.) to the year.

• Smith J. (2020a)
• Smith, J. (2020b)

How are corporate authors handled in APA reference order?

Corporate authors (organizations, government agencies) are treated the same as individual authors in the reference list. However, if the name of the corporate author is long, it may be abbreviated in the in-text citation after the first mention.

How are references with no date ordered in APA reference order?

For references without a date, use the abbreviation n.d. (for “no date”) in place of the year. These references are still ordered alphabetically by the author’s surname.

APA Style is the most common writing style used in college and career. Its purpose is to promote excellence in communication by helping writers create clear, precise, and inclusive sentences with a straightforward scholarly tone. It addresses areas of writing such as how to

• format a paper so it looks professional;
• credit other people’s words and ideas via citations and references to avoid plagiarism; and
• describe other people with dignity and respect using inclusive, bias-free language.

APA Style is primarily used in the behavioral sciences, which are subjects related to people, such as psychology, education, and nursing. It is also used by students in business, engineering, communications, and other classes. Students use it to write academic essays and research papers in college, and professionals use it to conduct, report, and publish scientific research.

In addition, APA Style provides you with a powerful tool that will hep you avoid deliberate or unintentional plagiarism. Please review the Avoiding Plagiarism Guide created by the APA experts to understand what two common types of plagiarism are and how to avoid them. 

Why is learning citations important? Citations help readers understand where the information used in your paper comes from, enabling them to trace the path of that information. When readers wish to explore a specific point or reference cited in the text, citations make it easier by providing information about your sources in a standardized format.

Besides showing readers where you obtained information, using citations also has a strong ethical purpose. In academic writing, it is important to credit ideas that are not your own. Citations allow you to integrate the ideas of others with your own thoughts in a fair and honest way.

The reference formats for APA Style manuals are as follows:

APA Style provides a foundation for effective scholarly communication because it helps authors present their ideas in a clear and concise, and organized manner.  Uniformity and consistency enable readers to (a) focus on the ideas being presented rather than formatting and (b) scan works quickly for key points, findings, and sources. When style works best, ideas flow logically, sources are credited appropriately, and papers are organized predictably and consistently. 

Students are encouraged to first learn about APA Style by reading works written in APA Style. A couple of guides created by APA experts from the American Psychological Association can help you with that:

Anatomy of a Journal Article   https://apastyle.apa.org/instructional-aids/anatomy-journal-article.pdf

Scholarly journal articles share a common anatomy or structure. Each part of an article serves a specific purpose. The handout of  Anatomy of a Journal Article explains how journal articles are structured and how to become more efficient at reading and understanding them. Understanding the structure of a scholarly article and the purpose of each part helps you grasp a strategy called targeted reading. Targeted reading means to read specific sections of research articles first to determine if the article seems useful for your research topic. This way you will save time, find useful article faster, and choose which articles to read in full.

Reading and Understanding Abstracts https://apastyle.apa.org/instructional-aids/reading-abstracts.pdf

Abstracts are short summaries of scientific research articles. The handout of Reading & Understanding Abstracts explains the definition and purpose of abstracts and the benefits of reading them, including analysis of a sample abstract. The skill of reading and understanding abstracts of scholarly articles not only saves time but also helps you conduct better research and write more effectively.

APA Style Writing Principles https://apastyle.apa.org/instructional-aids/writing-principles.pdf

The poster created by APA experts shows the three main principles of APA Style: clarity, precision, and inclusion and lists steps on how to achieve them. As a student writer, you always should write your academic paper with clarity, precision, and inclusion. 

Research Article Activity https://apastyle.apa.org/instructional-aids/apa-style-research-activity.pdf

Reading research articles is not an easy task for you as a student. The Research Article Activity designed by APA Style experts aims to make it easy to read and understand a scholarly article. This activity worksheet helps you find, cite, analyze, and summarize a research article. Completing this activity breaks down a lengthy research article into easily understandable chunks. This way helps you better understand the study in the article before you write about it.
