The Finer Points of APA Style: When Authors Have the Same Surname



Anneby Anne Breitenbach

There really is a certain satisfaction one gets from knowing how to use a tool correctly and well. That’s as true of an editorial style as it is of a lathe or a chisel. Like a well-made tool, APA Style has been crafted and honed for a specific purpose, in this case, “to advance scholarship by setting sound and rigorous standards for scientific communication” (p. xiii). Part of that communication for authors is to be sure to be as clear as possible about who their sources are. Thus, we’ve developed rules for distinguishing between sources if there is any risk that they might be confused. And using those rules correctly pleases me.

The reason behind them is clear, but the need to apply them is rare enough that using them is a skill. Let’s make sure you know how to use them too.

The Publication Manual says this: “If the reference list includes different authors with the same surname and the first initial, the authors’ full first names may be given in brackets” (p. 184).

Thus, if you cited Danny Thomas’s biography Make Room for Danny and Dylan Thomas’s A Child’s Christmas in Wales, your reference list entries would look like this:

Thomas, D. [Danny], & Davidson, B. (1991). Make room for Danny. New York, NY: Putnam. 
Thomas, D. [Dylan]. (1954). A child’s Christmas in Wales. Norfolk, CT: New Directions.

You would also want to distinguish between the two references in your in-text citation by using both first and last names. Your format would be (Danny Thomas, 1991) and (Dylan Thomas, 1954).

For further information on how to order references by authors with the same last name in the reference list, see our posts on Citing the Recurring Author With Crystal Clarity and Order in the Reference List!

How to Cite a Class in APA Style

Timothy.mcadooby Timothy McAdoo

Have you ever learned so much in a class that you wanted to cite the whole thing? If so, you’re not alone. Unfortunately, because a class is not a retrievable source, when you try to put together a reference, you won’t have a "where" there. There, there: Don’t worry, you do have other options!

Citing a Course Pack or Custom Textbookback to school

Sometimes people who ask about citing a course are really trying to cite the textbook, course pack, custom textbook, or other published materials used in the class. Our recent post on that topic provides a number of options.

Citing the Teacher’s PowerPoint File or Other Materials

In some cases, you might want to cite materials presented by the instructor that were not included in a course pack or a custom textbook (e.g., the instructor’s lecture itself or a PowerPoint presentation designed by the instructor). 

If the instructor has posted the materials somewhere online, you can cite them directly. But, it’s more likely that he or she is the only source for the materials. In that case, cite as a personal communication (see the Provide a Reliable Path to the Source section of our post on what belongs in a reference list).

Citing Your Own Class Notes 

In other cases, you might want to cite your own notes from the class. Again, because these notes will not be a retrievable source for most readers, cite them as a personal communication (see the Provide a Reliable Path to the Source section of our post on what belongs in a reference list).

Citing the Course Itself 

Your experience of attending the class simply cannot be replicated or retrieved. But, although the course itself is not retrievable, you may be able to find a description of the course on your school’s website. If you can find it online, you can cite it!

British Spellings

Timothy.mcadooby Timothy McAdooUnion Jack

This week, I look at another frequently asked APA Style question! Though the answer is true for other languages, too, the question is most often framed around British spellings.

Question

When an article or book title includes British spellings, should I “fix” them in my reference list? Also, what if I include a direct quote? Should I change spellings or use [sic]? I read somewhere that APA Style requires spellings to match those in the APA Dictionary of Psychology or Merriam-Webster’s Collegiate Dictionary.

Answer

The Publication Manual’s spelling guidelines apply only to the original writing in your paper.

For references, keep the spelling in titles and other elements exactly as they appeared in the original. That is, cite what you see.

For instance, if you cite this scholarly tome, keep that u in colour!

Trooping, T. C. (2012). Who rotated my colour wheel? London, England:
    Neal’s Yard Publishing.


Likewise, if you quote from the text, keep the original spellings. There’s no need to use [sic], as these are not errors.

    Trooping (2012) said, “only when you allow your colour wheel to turn will you recognise the aesthetic ‘complements’ you’ve received” (p. 10).

A Prescription for Success: How to Cite Product Information in APA Style

Jeffby Jeff Hume-Pratuch

Dear Style Experts,

I am writing a paper on the use of certain prescription and over-the-counter drugs. I took some of my information from those little package inserts that come in the box or bag when you get a prescription. I’m not sure how to cite it. Help!

—A Frustrated Pharmacologist in Philly


Dear Frustrated,

Fear not! We can solve this citation conundrum with our four favorite questions: Who? When? What? Where?

Let’s say you’re exploring treatments for head lice and need to cite the pharmaceutical insert for Ulesfia lotion.

  • Who is responsible for the content of the package insert? The distributor is listed on the insert as Shionogi Pharma, so we’ll put that in the author position (in accordance with our principle of “cite what you see”).
  • When was it made? The date on the insert is 2010, so that goes in the date position.
  • What is the document called? The title at the top of the insert (Highlights of Prescribing Information) is not too informative, but together with the name of the product, it should do the trick.
  • Where did it come from? The publisher and author of the package insert are the same, so we’ll use the author’s info in the publisher position.

And here is your reference:

Shionogi Pharma. (2010). Ulesfia lotion: Highlights of prescribing 
    information. Atlanta, GA: Author.

Text citation: (Shionogi Pharma, 2010)

If you retrieved the prescribing information from the manufacturer’s website (which also provides printable coloring pages of “Louie the Louse” to keep your kids occupied during the 10-min application process), you would cite it like this:

Shionogi Pharma. (2010). Ulesfia lotion: Highlights of prescribing 
    information. Retrieved from http://www.ulesfialotion.com/pdf/     Ulesfia_Prescribing_Information.pdf

Text citation: (Shionogi Pharma, 2010)

However, if your interest in pediculicides were purely academic, you might have downloaded the product insert from the FDA website, in which case you would cite it like this:

Shionogi Pharma. (2010). Ulesfia lotion: Highlights of prescribing 
    information. Retrieved from http://www.accessdata.fda.gov/scripts/     cder/drugsatfda/index.cfm

This technique can be applied to citations for any kind of product information, including package inserts for small appliances, hand tools, and adhesive tiles.

Missing Pieces: How to Write an APA Style Reference Even Without All the Information

Chelsea blog 2by Chelsea Lee

Most APA Style references are straightforward to write—the guidance and examples in Chapter 7 of the Publication Manual and on this blog make that possible. We’ve written a good deal about the architecture of a generic reference (the four basic pieces of author, date, title, and source). Sometimes, however, one or more of those pieces is missing, and writing the reference can get more difficult. This post will help you adapt the classic APA Style reference template to fit any situation where information might be missing, as well as show you how to create the corresponding in-text citations for those references. 

The table below shows how to write an APA Style reference when information is missing. It is also available for download as a PDF.

Title Variations

As shown in the table, the title of a document is only sometimes italicized, depending on the independence of the source. That is, do italicize the title of a document that stands alone (books, reports, etc.), but do not italicize the title of a document that is part of a greater whole (chapters, articles, etc., which are part of edited books or journals, respectively). Also do not italicize the titles of software, instruments, and apparatus (see §7.08 in the Publication Manual). If you have trouble determining whether something stands alone (such as for a document on a website), choose not to italicize. For examples and more explanation, see the blog post on capitalization and formatting of reference titles in the reference list.

Source Variations

As shown in the Position D column of the table, the source part of a reference list entry can vary as well. It should reflect either a retrieval URL (for online documents without DOIs), a publisher location and name (for print sources), or a DOI (for any document that has one, whether print or online). It is not usually necessary to include a retrieval date for online sources; one should be provided only if the source is likely to change over time, such as with an unarchived wiki page.

Sometimes source information is incomplete but with a little detective work you can find what you need; for example, if you know a publisher name but not its location, you can research the publisher to find the location. Even sources of limited availability can be cited in APA Style, including unpublished and informally published works (see §7.09) and archival documents and collections (see §7.10).

Note, however, that it is not possible to write a traditional APA Style reference if source information is truly missing. The purpose of an APA Style reference is to provide readers with information on how to locate the source that you used, and if you cannot tell them how to do so, you either have to find a substitute or cite the source as personal communication (see §6.20 in the Publication Manual).

Creating In-Text Citations

Create an in-text citation for any reference by using the pieces from Positions A and B in the table above. For most references, this will be the author and date (Author, date). For titles in Position A, use italics for works that stand alone (Title of Document, date) and quotation marks for works that are part of a greater whole (“Title of Document,” date). Retain square brackets for descriptions of documents in Position A ([Description of document], date). For examples and more explanation, see our post on formatting and capitalization of titles in the text.  

We hope this guide to missing pieces will help you as you create your APA Style references.

Citing a Special Issue or Special Section in APA Style

Timothy.mcadooby Timothy McAdoo

Typically you cite one thing at a time: anything from a journal article, a book or book chapter, a CD or mp3, a painting, a legal document, or classroom notes to a webpage, a YouTube video, a computer app, an e-book, or even a Twitter or Facebook post.

However, if you’ve ever read a special section or special issue of a journal, you know that the interrelated nature of these articles makes them a special case. In this post, I’ll detail how to reference and cite them.

Special

What Are Special Sections and Special Issues?

Articles in a special issue focus on the same topic, albeit from different vantage points. An editor often requests that authors submit the articles in order to highlight an important topic.

These issues will often, but not always, include an introduction from the editor. In this, he or she may expound on the importance of the topic, explain how the topic and the individual articles were chosen, detail how the included articles agree or disagree on major points, and/or provide a summary or analysis of the findings. Special issues also generally have a title, which sets them apart from regular issues that have just a volume and issue number.

Special sections are much like special issues, only smaller. They appear within a regular issue and may or may not have a title.


References

Of course, you may want to reference just one article within a special issue or special section. That’s okay! To do so, just use the journal article reference format, as usual. (You can find examples in this sample reference list.)

But, if you want to reference the entire special issue or special section, here’s what you need to know (as per Example 12 on page 201 of the Publication Manual).

The reference to a special issue should include the editor(s), the year, the title, [Special issue], the journal name, volume, and issue. The reference to a special section should include the editor(s), the year, the title, [Special section], the journal name, volume, page range of the section, and the DOI (if applicable).

Rotf, L. (Ed.). (2012). Beyond the LOLcats: Maru, Nyan Cat, and more
    [Special issue]. The Journal of Internet Memes, 115(3).

Jenkins, L., &, Astley, R. (Eds.). (2012). What’s up with Nyan Cat? [Special
    section]. International Journal of Memes, 32, 415–565.
    doi:27.0018/99-36me0w

If the issue has no editors, move the issue title to the author position.

Ennui or not ennui? Henri versus Keyboard Cat. (2012). Meme World, 19, 1–23.
    doi:27.0018/45-09h1ss

Citations

For the citation, use the editor name(s) and the year, as usual.

...when soaring across the sky (Jenkins & Astley, 2012).

When there are no editors, the in-text citation should include a shortened title in quotation marks and the year.

...present with a wide spectrum of emotional states (“Ennui or Not Ennui,” 2012).

Jr., Sr., and Other Suffixes in APA Style

Timothy.mcadooby Timothy McAdoo

 Henry W. “Indiana” Jones Jr.: “I like Indiana."
Henry W. Jones Sr.: “We named the dog Indiana.”

Much like the intrepid Dr. Jones, when writing a paper, you never know what riddles you’ll have to solve. (Unlike Indiana, you can always ask the APA Style team for help!) I hope to clear up one such riddle here: how to handle suffixes in author names.

Quick Summary (in case you need to make a dramatic exit before the end of this post!)*

"Jr.," “III,” or other suffixes are not included with in-text citations, but they are included in the reference list entries.

References

In a reference, include the suffix, set off with commas, as shown here:

Jones, H. W., Jr., & Jones, H. W., Sr. (1941). My adventures in Alexandretta.
      The Journal of Fictional Archeology, 1, 1–19. doi:46.34262/56637
Belloq, R. (1926). Shiny things. In B. C. Explorateur Jr. (Ed.), Artifacts lost and
      found
[E-reader version] (pp. 210–223). Paris, France: Gaxotte Publishing.

 

You may note that in the first example, because the names in the author portion of a reference are inverted, commas are needed before the suffix. In the second example, the suffix is in the editor name; because names are not inverted in the editor portion of the reference, the comma is not needed. More examples can be found in this post on citing book chapters in APA Style.

If the suffixes are numerals, alphabetize the entries by these numerals. For example,

Lucas, G., I. (2001). Tinkering with details (Vol. 1). Hollywood, CA:
      A.G.F.F.A. Publishing.
Lucas, G., II. (2012). You can always change it later. Hollywood, CA:
      A.G.F.F.A. Publishing.

 

Citations

For the citation in your text, do not include the suffix. Just use the author’s last name as you normally would:

...which would lead to a fear of snakes (Jones & Jones, 1941). Jones and Jones (1941) also found that...

 

*If you’re feeling adventurous, you can find the keys to this post throughout the Publication Manual. The fourth bullet on page 184 explains how to punctuate suffixes within a reference, and page 204 has an example with “Jr.” (Example 24). The guideline for alphabetizing appears in the second bullet at the top of page 182.

How to Cite Pseudonyms

DBby David Becker

“Whom do I cite: Mark Twain or Samuel Clemens?”

In this post, I provide some basic guidelines and suggestions for citing pseudonyms. There’s no official APA Style rule on this, but a few criteria can help you decide how to present the information.  I use republished books as examples here—to learn more about citing republished works, see a recent post on citing sheet music.

Citing pseudonyms can seem tricky at first, but it becomes much simpler when you take into account one of APA Style’s key mottos: Cite what you see.  When it comes to citing an author, cite whatever name is used by the source, whether it be a real name or a pseudonym.  For example, The Adventures of Tom Sawyer lists Mark Twain as its author, not Samuel Clemens, so you should cite the author’s pseudonym rather than his real name: 

Twain, M. (2010). The adventures of Tom Sawyer. Berkeley: University of California Press. (Original work published 1876)

In-text citation: (Twain, 1876/2010)

However, some pseudonyms can still be difficult to cite.  What if you’re citing a work by the Dalai Lama, for example?  Do you cite him as “Lama, D.” in the reference list and as just “Lama” in an in-text citation?  Well, the “Dalai” cannot be removed from “Lama” without losing meaning, so the author’s name should be spelled out in full as “Dalai Lama.”  Also, “Dalai Lama” is a title, so spelling it out in full makes that especially clear:

Dalai Lama. (1991). Freedom in exile: The autobiography of the Dalai Lama. New York, NY: HarperPerennial.

In-text citation: (Dalai Lama, 1991)

This same rule applies to Dr. Seuss, where the “Dr.” and the “Seuss” cannot be separated from one another without creating some confusion:

Dr. Seuss. (1985). The cat in the hat. New York, NY: Random House. (Original work published 1957)

In-text citation: (Dr. Seuss, 1957/1985)

You might have noticed that in both of the above reference list examples, there is a period after the author’s name.  If you’re wondering why that is, then read this post about punctuating reference list entries.

You may have also noticed in a previous post about citing recorded music in APA Style that Dr. Seuss is cited as “Geisel, T.” in a sample reference list entry for the song “Welcome Christmas!” from How the Grinch Stole Christmas.  Why was he cited by his real name, Theodor Geisel, for this song but by his pseudonym for the book The Cat in the Hat?  This is where the “cite what you see” motto comes into play again.  “Dr. Seuss” is listed as the author of The Cat in the Hat, whereas the lyricist for “Welcome Christmas!” is listed as “Theodor Geisel.”  In each case, you use whatever name was provided by the source you’re citing as the author in your citations.  This rule also applies to the Dalai Lama who occasionally goes by his birth name, Tenzin Gyatso, when authoring some books.

The “cite what you see” motto helps to keep your citations simple and uncomplicated without struggling to find extraneous information, yet it still provides readers with enough information to follow your sources.  It is an important rule of thumb to keep in mind when you are citing any source.

See sections 6.11–6.15 and 6.27 in the Publication Manual for more information about citing authors in in-text citations and reference lists.

The Proper Use of Et Al. in APA Style

Chelsea blog 2 by Chelsea Lee

Academic writing is full of little conventions that may seem opaque to the uninitiated. One of these is the Latin phrase et al., an abbreviation meaning “and others.” It is used to shorten lists of author names in text citations to make repeated referencing shorter and simpler. Note that et al. is italicized in this post when I am using it as a linguistic example, but it should not be italicized when you are using it as part of a reference citation.

General Use of Et Al.

Below is a chart showing when to use et al., which is determined by the number of authors and whether it is the first time a reference has been cited in the paper. Specifically, articles with one or two authors include all names in every in-text citation; articles with three, four, or five authors include all names in the first in-text citation but are abbreviated to the first author name plus et al. upon subsequent citations; and articles with six or more authors are abbreviated to the first author name plus et al. for all in-text citations.

Number of authors

First text citation (either parenthetical or narrative)

Subsequent text citations (all)

One or two

Palmer & Roy, 2008

Palmer & Roy, 2008

Three, four, or five

Sharp, Aarons, Wittenberg, & Gittens, 2007

Sharp et al., 2007

Six or more

Mendelsohn et al., 2010

Mendelsohn et al., 2010

 

Avoiding Ambiguity

However, sometimes abbreviating to the first author name plus et al. can create ambiguity. Here are two example references, as also discussed in a previous post about reference twins.

Marewski, J. N., Gaissmaier, W., & Gigerenzer, G. (2010). Good judgments do not require complex cognition. Cognitive Processing, 11, 103–121. doi:10.1007/s10339-009-0337-0
Marewski, J. N., Gaissmaier, W., Schooler, L. J., Goldstein, D. G., & Gigerenzer, G. (2010). From recognition to decisions: Extending and testing recognition-based models for multi-alternative inference. Psychonomic Bulletin & Review, 17, 287–309. doi:10.3758/PBR.17.3.287

The first in-text citations to each of these would be as follows:

  • (Marewski, Gaissmaier, & Gigerenzer, 2010)
  • (Marewski, Gaissmaier, Schooler, Goldstein, & Gigerenzer, 2010)

For the subsequent in-text citations we would usually abbreviate these studies to the first author name plus et al.; however, doing so here would produce two Marewski et al. (2010) citations, leaving the reader unable to tell which one you mean (if the citations were from different years we would not have this problem, because the years would tell them apart). The solution here is to spell out as many names as necessary (here, to the third name) upon subsequent citations to tell the two apart: 

  • (Marewski, Gaissmaier, & Gigerenzer, 2010)
  • (Marewski, Gaissmaier, Schooler, et al., 2010)

Notice that for the first reference, this means that all citations to this source include all three names. For the second reference, the two remaining names can be abbreviated to et al.

A Quirk of Et Al.

Finally, be careful of a quirk of et al., which is that it is plural—that is, it must replace at least two names (or, put another way, it cannot stand for only one name). So, if you have worked through a reference and only one name is left to abbreviate, you must spell out all the names every time to tell the two apart.  Here is an example with three authors, although the principle holds no matter how many total authors there are:

Berry, C. J., Henson, R. N. A., & Shanks, D. R. (2006). On the relationship between repetition priming and recognition memory: Insights from a computational model. Journal of Memory and Language, 55, 515–533. doi:10.1016/j.jml.2006.08.008
Berry, C. J., Shanks, D. R., & Henson, R. N. A. (2006). On the status of unconscious memory: Merikle and Reingold (1991) revisited. Journal of Experimental Psychology: Learning, Memory, and Cognition, 32, 925–934. doi:10.1037/0278-7393.32.4.925

The correct in-text citations would be written as follows for all citations of these two references:

  • (Berry, Henson, & Shanks, 2006)
  • (Berry, Shanks, & Henson, 2006)

Avoid the following common incorrect ways of citing these references in text:

  • (Berry, Henson, et al., 2006), (Berry et al., 2006a)
  • (Berry, Shanks, et al., 2006), (Berry et al., 2006b)

A Final Note

If it happens that all the author names are exactly the same and the studies were published in the same year as well, the method of citation described in the reference twins post applies. Namely, use et al. as usual but also include lowercase letters after the year (2010a, 2010b, etc.) to tell the references apart.

For more information and examples on citing references in text, see Chapter 6 of our sixth edition Publication Manual (pp. 174–179). You may also be interested in our primer on how in-text citations work and our piece on common et al.-related errors.

Reference Twins: Or, How to Cite Articles With the Same Authors and Same Year

Chelsea blog 2
by Chelsea Lee

Have you ever been friends with a pair of identical twins? Twins who looked so alike that, at first, telling them apart all hinged on finding that distinguishing freckle, or hoping someone else would call them by their names so you could memorize what clothes each was wearing that day? In the social sciences, there is a longstanding tradition of twin research, but this post refers to twins of another kind: reference twins. Specifically, this post addresses how to cite multiple articles by the same authors that were published in the same year so that everyone can easily tell them apart.


A Solution for Identical Twins

In essence, the solution to the reference twin problem is not much different from how twins are told apart at birth: Just as twins are referred to as “Baby A” and “Baby B,” “twin references” are also given letters to tell them apart. Specifically, lowercase letters are added after the year (2011a, 2011b, etc.), and the references are alphabetized by title to determine which is “a” and which is “b.” Here is an example:

Koriat, A. (2008a). Easy comes, easy goes? The link between learning and remembering and its exploitation in metacognition. Memory & Cognition, 36, 416–428. doi:10.3758/MC.36.2.416
Koriat, A. (2008b). Subjective confidence in one’s answers: The consensuality principle. Journal of Experimental Psychology: Learning, Memory, and Cognition, 34, 945–959. doi:10.1037/0278-7393.34.4.945

In the text, citations would be styled as follows: (Koriat, 2008a) and (Koriat, 2008b).

For references that are in press or that have no date (signified by n.d., which stands for “no date”), use the following forms for the date: (in press-a), (in press-b), (n.d.-a), and (n.d.-b), and so forth.

A Solution for Not-Quite Twins

However, be careful that your references are true identical twins. That is, the method described above applies only when all author names are the same and appear in the same order. If any of the names or the order is different, then the references are distinguished in a different way: by spelling out as many author names as necessary to tell them apart.  Let’s use the following two references as an example:

Marewski, J. N., Gaissmaier, W., & Gigerenzer, G. (2010). Good judgments do not require complex cognition. Cognitive Processing, 11, 103–121. doi:10.1007/s10339-009-0337-0
Marewski, J. N., Gaissmaier, W., Schooler, L. J., Goldstein, D. G., & Gigerenzer, G. (2010). From recognition to decisions: Extending and testing recognition-based models for multi-alternative inference. Psychonomic Bulletin & Review, 17, 287–309. doi:10.3758/PBR.17.3.287

The first in-text citations to each of these articles would be as follows:

  • (Marewski, Gaissmaier, & Gigerenzer, 2010)
  • (Marewski, Gaissmaier, Schooler, Goldstein, & Gigerenzer, 2010)

Now, what about subsequent in-text citations? Usually we would abbreviate studies with three or more authors to the first author name plus et al. (Latin for “and others”); however, doing so here would produce two Marewski et al. (2010) citations, leaving the reader unable to tell which one you mean. The solution is to spell out as many names as necessary (here, to the third name) upon subsequent citations to tell the two apart: 

  • (Marewski, Gaissmaier, & Gigerenzer, 2010)
  • (Marewski, Gaissmaier, Schooler, et al., 2010)

Notice that for the first reference, this means that all citations to this source will include all three names. For the second reference, the two remaining names can be abbreviated to et al. (Note, however, that if only one name remains to distinguish the references, that name must be spelled out with all the rest because et al. is plural—it cannot stand for only one name.
