How to Cite a Mobile App

Chelsea blog 2

by Chelsea Lee APA Concise Dictionary

Mobile applications, or apps, are a type of software 
that runs on devices such as smartphones and tablet computers (such as iPhones, iPads, and Androids) as well as web browsers (such as Chrome, Internet Explorer, and Firefox). Apps serve a multitude of purposes, from entertaining you while you wait in line to providing you a way to look up medical information without having to lug around a stack of books. 

When you use information from an app in a paper, cite the app in APA Style. The general citation format is as follows:

Rightsholder, A. A. (year). Title of Software or Program (Version number) [Mobile application software]. Retrieved from http://xxxxx

Note that the rightsholder may be an individual but is often a group or company, as shown below, and that the date reflects the year the version you used was released, even though previous versions may have been released in different years.

Here is an example citation for a whole app:

Skyscape. (2013). Skyscape Medical Resources (Version 1.17.42) [Mobile application software]. Retrieved from http://itunes.apple.com

If the app is a reference work (like a dictionary, encyclopedia, or medical reference), it’s also possible to cite an entry in the app, just like you can cite an entry in a print or electronic reference work. The title of the entry goes at the beginning of the reference, followed by the year that version of the app was released and then information about the app itself.

Here is an example citation for an entry in a reference work app:

Diabetes. (2013). In Epocrates Essentials for Apple iOS (Version 5.1) [Mobile application software]. Retrieved from http://www.epocrates.com/mobile/iphone/essentials

For further information and more examples of not only apps but all sorts of electronic references, check out the APA Style Guide to Electronic References (pp. 28–30).

Introduction to APA Style Legal References

Melissa.photo

 

by Melissa


Writers sometimes try to squeeze a reference for a statute or a court decision into the same format as a journal article, essentially trying to shove a square peg into a round hole. It won’t fit, it won’t look quite right, and it won’t be as useful to your readers as it could be.

There’s a better way. Instead of contorting legal references like pretzels, consult one or more of the following style resources: Appendix 7.1 in the Publication Manual of the American Psychological Association, this blog, and the specialized style resources discussed below.

 

1. Appendix 7.1 in the Publication Manual

When creating APA Style legal references, your first and best resource is the Publication Manual’s Appendix 7.1: References to Legal Materials (pp. 216–224). There, you’ll find sample references for the legal documents that are most commonly used in psychology research, including court decisions, statutes, administrative regulations, and executive orders.

The reference examples in Appendix 7.1 are drawn from The Bluebook: A Uniform System of Citation, which is an authoritative source for legal citations and the primary style guide used by legal scholars and other professionals in that field. The reference and citation formats that you’ll find in Appendix 7.1 are a hybrid of APA Style and Bluebook style, adapted to both fit well in an APA Style article and provide the unique information that will allow your readers to find the referenced legal document.

 

2. The APA Style Blog

The APA Style Blog already provides some resources for legal references. Citation of the U.S. Constitution is discussed in How to Cite the U.S. Constitution in APA Style. Capitalization of the names of legal documents is discussed in Do I Capitalize This Word?

New blog posts to help you find, reference, and cite other legal materials in APA Style are on the way. These posts will cover the following topics:

As each topic is added to the blog, we’ll include a link to the relevant post in the above list.

 

3. Additional Resources

The Bluebook. If you’re working with more complex legal references that require you to go beyond the scope of Appendix 7.1, be sure to consult The Bluebook, which provides citation formats for constitutions, international treaties, domestic and foreign statutes, legislative bills and resolutions, administrative regulations and proceedings, executive orders, legal briefs and other court filings, reported and unreported court decisions, and many other legal documents.

Because Bluebook citation style relies heavily on footnotes and doesn’t include the reference list and name–date citations that are the hallmarks of APA Style, when you use a legal reference format from The Bluebook, consult Appendix 7.1 in the Publication Manual and, using the create-a-reference skills that you learned from our Frankenreference blog post, adapt the reference to closely follow the examples in Appendix 7.1.

Law Librarian. The law mutates. New laws that alter or overrule existing laws are passed all the time. You may wish to consult a law librarian to ensure that your references are complete and correct and that the law you are citing has not been superseded or overturned.

Additional Information Online. Finally, one other resource that I find helpful in my own research is the online guide Introduction to Basic Legal Citation by Peter W. Martin (an emeritus law professor at Cornell University). This is not an official source, so if you consult it, be sure to seek additional verification in The Bluebook.

Alphabetizing “In Press” and “No Date” References

Tyler

 

 

by Tyler Krupa

You may already know that references with the same authors in the same order are arranged by year of publication, the earliest first (see the sixth edition of the Publication Manual, p. 182):

Meints, K., Plunkett, K., & Harris, P. L. (2002).

Meints, K., Plunkett, K., & Harris, P. L. (2008).

But do you know what to do when a group of references with the same author(s) in the same author order contain “in press” and “no date” publication dates? Alphabetizing these references is easy as long as you remember the following two points:

1. An “in press” work has yet to be published, so if you have one or more references that contain a publication year, these references will always come before an “in press” reference because they’ve already been published.

2. When dealing with “no date” references, simply follow the same “nothing precedes something” guidance that the Publication Manual gives regarding alphabetizing author surnames in the reference list (see p. 181). Using this guideline, “no date” references should always precede references with “some date.” Also remember that “no date” is abbreviated as “n.d.” in both the reference list and the in-text citations (see p. 185).

Here are some examples that show the correct ways to alphabetize these types of references in the reference list:

Johnson, K., & Jones, B. B. (2012).

Johnson, K., & Jones, B. B. (in press).

Taylor, H., Carter, N., & Beckett, S. (n.d.).

Taylor, H., Carter, N., & Beckett, S. (2010).

Taylor, H., Carter, N., & Beckett, S. (in press).

University of Florida. (n.d.).

University of Florida. (2012).

Also remember that if you have two or more “in press” or “no date” references with the same authors in the same order, you should use lowercase letters—a, b, c, and so forth—after the publication date and alphabetize the references by their titles (excluding A, An, and The; see p. 182 in the Publication Manual). The only difference between these types of references and references with publication years is that “in press” and “no date” references contain a hyphen before the a, b, and so forth:

American Speech-Language-Hearing Association. (n.d.-a). The knowledge . . .

American Speech-Language-Hearing Association. (n.d.-b). A strategy to . . .

Schafer, G., & Plunkett, K. (2011a). The power . . .

Schafer, G., & Plunkett, K. (2011b). Task complexity . . .

Schafer, G., & Plunkett, K. (in press-a). The rapid learning . . .

Schafer, G., & Plunkett, K. (in press-b). Sometimes a child . . .

We hope that these examples clear up this point of possible confusion.

A Stylish Guide to Holiday Viewing

Jeff

 

by Jeff Hume-Pratuch

Winter Storm Draco is currently bringing a better-than-average chance of a white Christmas to the Midwest. Although it’s not slated to affect us here at APA Style HQ, I sort of envy you folks in Des Moines and Milwaukee—there’s nothing better on a snowy night than curling up with a warm drink and watching some holiday TV.

With that in mind, here are a few examples of how to cite the can’t-miss fare that’s streaming across the airwaves this weekend. Grab a seat by the fire and pass the cocoa!

Burton, T. (Producer), & Selick, H. (Director). (1993). The nightmare before Christmas [Motion picture]. United States: Touchstone.

Roman, P. (Producer & Director). (2000). Grandma got run over by a reindeer [Television special]. Atlanta, GA: Cartoon Network.

Sager, T. (Writer), & Scardino, D. (Director). (2007). Ludachristmas [Television series episode]. In T. Fey (Executive producer), 30 Rock. New York, NY: National Broadcasting Company.

Smith, G. (Executive producer), Hemion, D. (Executive producer), & Binder, S. (Director). (1978). The Star Wars holiday special [Television special]. New York, NY: CBS Broadcasting.

Stem, J. D. (Writer), Weiss, D. (Writer), & Muzquiz, R. (Director). (1996). Chanukah [Television series episode]. In V. Coffey, G. Csupo, & A. Klasky (Executive producers), Rugrats. New York, NY: Nickelodeon.

How to Cite a Podcast

Timothy.mcadooby Timothy McAdoo

Podcasts are new—okay podcasts were new about 10 years ago—but the reference format will look familiar. As with other retrievable documents, just follow the basic guidelines for creating a reference: Tell the reader who, when, what, and where. When in doubt, this post on citing something you found on a website always helps me!

For a podcast, the “who” might be a producer, a writer, or a speaker. You can use parentheses to identify the contribution of the person in the "who" position—when you know it.

For example, here’s a reference for an audio podcast:

Rissian, L. C. (Producer). (2012, May 4). Twelve parsecs [Audio podcast].
    Retrieved from http://itunes.apple.com

Notice that the “Retrieved from” line includes the homepage URL, not the full URL, of where you found the podcast. (In this example, it was an iTunes page, but it could be an organization's webpage or even a website devoted solely to the podcast.) A full URL might feel more direct, but the homepage URL is more likely to be correct as the days, months, and years pass between when you create your reference and when a reader sees your work and wants to find the podcast.

Video podcasts are also new—okay video podcasts were also new about 5 years ago—but you can cite them in the same fashion. In an earlier post, you’ll find an excellent sample reference to a video podcast.

How to Cite Course Packs, Custom Textbooks, and Other Classroom Compendiums


Jeffby Jeff Hume-Pratuch

If you’ve taken a college course in the last 20 years, you’ve probably used a course pack—a collection of information put together specifically for your class. Course packs can be as simple as a stapled packet or as fancy as a hardbound book with a four-color cover. They’re usually compiled by the instructor from relevant articles, chapters, and original material; they may be printed by the college print shop, outsourced to a local copy shop, or ordered through a custom textbook manufacturer. It’s increasingly common to provide all or part of the book in electronic form as well.

Course packs are seldom cited in journal articles, but students are often given the assignment of writing on a specific extract from the textbook. The plethora of sources in a course pack often creates a conundrum for students: Who’s the author? Who’s the publisher? Below I suggest a technique for handling the types of sources most commonly encountered in course packs.

Previously Published Articles or Chapters


Let’s say you’re working from a course pack for a neuropsychology class, and you need to cite a journal article included in it. The source should be clearly identified as part of the copyright/permissions statement, which is required by law.1  In this case, you can eliminate the middleman—just cite it as if you found it in the original source:

Wenner, A. M. (1962). Sound production during the waggle dance of the 
honey bee. Animal Behaviour, 10, 79–95. doi:10.1016/
0003-3472(62)90135-5.

 

Original or Unattributed Material


Instructors frequently include unpublished material in their course packs, particularly in rapidly developing areas of research. Since the only source for this material is the course pack itself, treat it as part of an anthology compiled by the instructor and published by the university. If authorship is not stated, treat it as an unauthored work. The title of the compilation is whatever is on the cover or title page—often (but not always) this consists of the course name and number, as in the first example below:

Diagram of the tibia–basitarsis joint in Apis melifera. (2011). In B. 
Haave (Comp.), NEU 451: Movement and perception (pp. 44–45).
Davenport, IA: St. Ambrose University.

MacGyver, A. (1990). Five steps to repelling an attack by killer bees.
In R. D. Anderson (Comp.), Selected readings in survival, escape,
and evasion
(pp. 31-34). Davenport, IA: St. Ambrose University.


Supplemental Material


Many custom textbook publishers offer supplemental materials such as CDs, DVDs, or online materials that are accessible only with the purchase of the text. Since these are essentially extensions of the course pack or text itself, it makes sense to cite them as supplemental materials:

“Varroa mite blues” and other songs of the honey bee [Supplemental 
material]. (2012). In B. Haave (Comp.), NEU 451: Movement and
perception
(pp. 44–45). Davenport, IA: St. Ambrose University.


If you find other challenges in citing materials from course packs, please let us know in the comments below.

1 Prior to 1991, course packs were often reproduced without acknowledging or obtaining permission from copyright owner(s), under the assumption that all copying for educational purposes qualified as “fair use.” Two federal cases (Basic Books Inc. v. Kinko’s Graphics Corp, 1991, and Princeton Univ. v. Michigan Document Servs., 1996) established that there is no educational exception for course packs under U.S. copyright law. See http://fairuse.stanford.edu/Copyright_and_Fair_Use_Overview/chapter7/7-a.html for a good overview of this issue.

How to Cite Materials From Meetings and Symposia

Jeff

 

by Jeff Hume-Pratuch

If you’re attending the APA Convention this week in Orlando, Florida, you’ll probably come away with some great new research to use. But how to cite it? Let’s dive right in with a few examples.


Papers and Poster Sessions

Adams-Labonte, S. K. (2012, August). Daytime impairment due to  
college students’ technology use during sleep: Similarities to
sleep apnea. Poster session presented at the meeting of the
American Psychological Association, Orlando, FL.
Nguyen, C. A. (2012, August). Humor and deception in advertising: When 
laughter may not be the best medicine. Paper presented at the
meeting of the American Psychological Association, Orlando, FL.


Notice that the date field contains not only the year but also the month of the conference.


Symposia
A symposium is a bit like a live-action edited book: Several authors come together under the leadership of the chair to pool their knowledge about a topic.

Krinsky-McHale, S. J., Zigman, W. B., & Silverman, W. (2012, August). 
Are neuropsychiatric symptoms markers of prodromal Alzheimer’s
disease in adults with Down syndrome? In W. B. Zigman (Chair),
Predictors of mild cognitive impairment, dementia, and mortality in
adults with Down syndrome.
Symposium conducted at the meeting
of the American Psychological Association, Orlando, FL.

Convention Blogging
Leading up to the convention, APA staff have been blogging about featured speakers and presentations. Here’s how you would cite one of those blog posts.

Mills, K. I. (2012, July 25). Why do people hurt themselves? [Blog post]. 
Retrieved from http://apaconvention.com/2012/07/20/why-do-people-
hurt-themselves


Published Proceedings
APA generally does not publish proceedings of the annual convention (although selected abstracts are available in the online program). However, APA often publishes proceedings of more specialized meetings. Here’s an example:

Parsons, O. A., Pryzwansky, W. B., Weinstein, D. J., & Wiens, A. N. 
(1995). Taxonomy for psychology. In J. N. Reich, H. Sands, & A. N.
Wiens (Eds.), Education and training beyond the doctoral degree:
Proceedings of the American Psychological Association National
Conference on Postdoctoral Education and Training in Psychology

(pp. 45–50). Washington, DC: American Psychological Association.


Increasingly, proceedings are being made available on CD to reduce publishing costs. If that’s the case with your source, just add [CD] after the title. If the proceedings are published online, substitute “Retrieved from URL” for the publisher and location.


If you’re attending the APA convention in Orlando this week, do stop by one of our publishing seminars (to find them, go to http://forms.apa.org/convention/index.cfm?convention=Division and search on “P&C - APA Publications and Communications Board”). See you next year at the APA convention in Hawaii!

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.

What’s missing?

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.

How to Create a Reference for a YouTube Video

Daisiesby Stefanie

Halloween is coming! What better time of year to track down some of your favorite scary YouTube videos to frighten your friends or prove your position on the existence of ghosts? If you spin your YouTube search into research (“The Startle Reflex: Can You Use It to Identify Individuals With Antisocial Personality Disorder?”), here is how to create a reference for your stimulus. (By the way, none of the sample videos given below include something that jumps out at you. Experimentation has proved that my startle reflex is just fine, thanks.)

The general format is as follows:

Author, A. A. [Screen name]. (year, month day). Title of video
     [Video file]. Retrieved from http://xxxxx

For retrievability, the person who posted the video is put in the author position. You might have noticed that the template shows both a typically formatted author name and a place for a screen name, and here's why: On YouTube and many other video-posting websites, users must post under a screen name. This screen name is integral to finding the video on YouTube, so including it in the reference is important. Sometimes, however, the real name of the individual who posted the video is also known. The individual's real name likely better connects him or her to the real world as well as to any other sources he or she may have provided for your paper (e.g., an author who wrote an article and also produced a YouTube video). Providing the real name, when available, aids the reader by highlighting these interconnections and also makes it possible to alphabetize the reference among any other references by that same author in the reference list. Thus, the reference format for a YouTube video includes both elements when both elements are available.

Example:

Apsolon, M. [markapsolon]. (2011, September 9). Real ghost girl 
     caught on Video Tape 14 [Video file]. Retrieved from 
     http://www.youtube.com/watch?v=6nyGCbxD848

(The capitalization [or lack thereof] in the screen name is in keeping with how it appears online.)

On YouTube, the screen name is most prominent. If the user’s real name is not available, include only the screen name, without brackets:

Screen name. (year, month day). Title of video [Video file]. Retrieved 
     from http://xxxxx

 

Example:

Bellofolletti. (2009, April 8). Ghost caught on surveillance camera
     [Video file]. Retrieved from http://www.youtube.com/watch?v
     =Dq1ms2JhYBI&feature=related

In text, cite by the author name that appears outside of brackets, whichever one that may be. For example, the two example references provided above would be cited as follows: (Apsolon, 2011; Bellofolletti, 2009).

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. This topic will be elaborated upon in an upcoming post.)

For more information and examples of 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.
