Citation Guide

 APA Citation Handout (PDF): a four-page quick guide to citing in APA format

Every time you quote or paraphrase someone else’s work, you must indicate:

• who wrote the work
• what is it called
• and where we (the reader) can find a copy.

You give us this information in two places:

1. In the paragraph where you are quoting or paraphrasing. This is called an In Text or Parenthetical Citation because you will put brief information about the work in parentheses. Check out our guidelines and examples in the left-hand column.
2. In the References page at the end of the paper. This is where you put all of the information we need to find a copy of the works you used in your paper. Check out our guidelines and examples in the left-hand column. (See the Sample Student Paper on the official APA Style Guide)

The official APA Style & Grammar Guidelines includes a section on Paper Format, which includes information on:

• Page Headers: For student papers, the page header consists of the page number only. No running head! 
• Font: Recommended fonts include 11-point Calibri, 11-point Arial, and 12-point Times New Roman
• Title Page: Should include the title, author names, author affiliation, course number and name, instructor name, assignment due date, and page number.  Title Page Quick Guide
• Sample Papers

For detailed explanation and sample title pages, see the official  APA Style Guidelines Title Page Setup section and Student Title Page Guide (PDF).

The student title page is the first page of your paper and includes:

• paper title (centered and bolded)
• author name
• author affiliation (Northeast Wisconsin Technical College)
• course number and name
• instructor name
• assignment due date

When you quote or paraphrase from a source (book, article, or webpage) in your paper, you need to insert an in-text citation. 

This citation typically consists of the author’s name, year of publication, and page number in parentheses at the end of the sentence.

“This is a direct citation” (Chapman, 2019, p. 126).

When paraphrasing the idea in your own words, do not use quotation marks and do not include a page number (Jackson, 1999).

Another option is to use the author’s name in the sentence, followed directly by the year in parentheses, with the page numbers in parentheses at the end of the sentence.

According to Chapman (2019), "This is a direct citation" (p. 216).

Jackson (1999) explains that when paraphrasing the idea in your own words, do not use quotation marks and do not include a page number.

Exceptions

• What if there's more than one author, or no author?
• What if a government agency or some other group is the author?
• What if there are no page numbers and my instructor wants me to include paragraph numbers?

Additional Resources from the Excelsior College Online Writing Lab:

• APA Citations in the Body of Your Paper: multiple examples
• APA Side by Side: Examples that "provide reference information and corresponding in-text citation information for common source types and situations you are likely to encounter while working with your sources". 

Examples

Direct Quoting - When you are using someone else's exact words.

1. If you are using a quote that is less than 40 words, enclose the quote in quotation marks and add the author’s name** (unless it is already in the sentence), year of publication and page numbers (if there are any) in parentheses.  Place this reference where a pause would occur or at the end of the sentence.  Punctuation marks should be placed after the parenthetical citation. You also will need to add each work from which you cite to your Works Cited page. Here are two examples:

   • The article goes on to say that “People don't do derby just for exercise but usually because it becomes a part of who they are” (Fagundes,  2012, p.1098).

   • Fagundes (2012) believes that roller derby gives participants "a chance to feel like a superstar" (p. 1098).

2. If you are using a quote that is more than 40 words, do not use quotation marks. Instead, put the quote on a new line and indent the whole block approximately 1/2 inch from the left margin. Keep the quote double-spaced. Remember to add a parenthetical citation and put the work on your Works Cited page.  The parenthetical citation comes after the final punctuation mark. For example:

He asserts the following:

More importantly, though, the notion of competing under derby names was a perfect fit with the recent reimagination of the sport as a punk-rock spectacle that allowed, and encouraged, participants to develop outrageous public personas. The story of derby-name emergence probably has more to do with coincidence and path dependence than with conscious design. Derby pioneer Ivanna S. Pankin’s classic derby name pre-dated her founding of Arizona Roller Derby in 2003. Rather, it was a handle and email address she used as a musician in Phoenix’s punk rock scene. When she publicized her nascent league using the alias Ivanna S. Pankin, and the entire Austin scene was already using skate names, the leagues that popped up in their wake followed suit,33 and the practice of using colorful nicknames has been used by virtually all derby leagues and skaters since. (Fagundes, 2012, pp.1093-1094)

Paraphrasing or Referring to Works - Acknowledging the sources you used in your research.

• If you mention the author’s name in the paragraph, then just put the date in parentheses.

  Fagundes believes it is hard to pin down when the practice of skating under a pseudonym began (2012).

• If you do not mention the author’s name, then include the author’s name in parentheses before the date.

  It is hard to pin down when the practice of skating under a pseudonym began (Fagundes, 2012).

Author-Date Citation System - Official APA Style and Grammar Guidelines

Two authors

• Use and between the authors' last names within the text, and use the & in the parentheses.
• Add the year and page numbers (if there are any). 
• (Pence & Chapman, 2016, p. 52)

Three or more authors

No author

• Include the title and year of publication. If the title is long (more than 3 words), shorten it.
• If the title of the work is not italicized in the reference (article, book chapter, page or section on a website), use the first word or two of the source in quotation marks.
• If the title of the work is italicized in the reference (book, entire website), use the first word or two of the source in italics.
• For example, if you had an article with the title Practical oral care for people with intellectual disability, the parenthetical citation would look like ("Practical oral," 2014). 

Government Agency as Author

Two to 20 authors: 

• List by their last names and initials, separated by a comma. Put an & between the final two names.

• Brooks, K., & Dunn, R.                        

• Knowles-Carter, B., Carter, B.I., & Carter, S.

21 or more authors: 

• List by last names and initials; commas separate author names. 

• Include the first 19 authors’ names, insert an ellipsis ... (but no ampersand), and then add the final author’s name:.

• Author, A. A., Author, B. B., Author, C. C., Author, D. D., Author, E. E., Author, F. F., Author, G. G., Author, H. H., Author, I. I., Author, J. J., Author, K. K., Author, L. L., Author, M. M., Author, N. N., Author, O. O., Author, P. P., Author, Q. Q., Author, R. R., Author, S. S., . . . Author, Z. Z.. (2018). 

No author:

• Start with the article title: Practical oral care for people with intellectual disability.

• or Book title: Evicted: Poverty and profit in the American city. 

According to the APA Manual (Section 8.28 Written Material Without Page Numbers), you have three main options when quoting sources that do not have page numbers (webpages, eBooks, etc.). Use the option that will best help your reader find the quotation in the source:

Provide a paragraph number; you will probably have to count them manually.

According to the IceBridge Project leader, " in addition to the airborne and satellite measurements, scientists will be out on the ice taking height and density measurements as well" (Gray, 2019, para. 6). Source

Provide a heading or section name.

Medical consensus is that the flu is spread "mainly by tiny droplets made when people with flu cough, sneeze or talk" (Centers for Disease Control and Prevention, 2019, How Flu Spreads section). Source

Provide an abbreviated heading or section name in quotation marks if the name is too long or unwieldy to cite in full.

Research has shown that an average of 8% of the U.S. population experiences flu symptoms each flu season," with a range of between 3% and 11%, depending on the season" (Centers for Disease Control and Prevention, 2019, "How Many People" section). Source

One of the basic principles for citing is "to cite a specific part of a source" by including "an author–date citation for the work plus information about the specific part."

There are many possible "specific parts" to cite, including pages, paragraphs, sections, chapters, video time stamps, and slide numbers in PowerPoint presentations.

For examples, see Citing Specific Parts of a Source.

• If the newspaper article is from a library database, provide the title of the newspaper and any volume, issue, and/or page numbers that are available for the article. Do not include database information in the reference. If the article does not have volume, issue, or page numbers available, the reference in this case ends with the title of the newspaper.
• If the newspaper article is from an online newspaper that has a URL that will resolve for readers, include the URL of the article at the end of the reference. If volume, issue, and/or page numbers for the article are missing, omit these elements from the reference.
• If the article is from a news website (e.g., CNN, HuffPost)—one that does not have an associated daily or weekly newspaper—use the format for a webpage on a news website instead.

Basic Format on Reference Page

• Spell out the full name of a group author in the reference list entry, followed by a period.
• While an abbreviation for the group author can be used in the text (e.g., NIMH for National Institute of Mental Health), do NOT include an abbreviation for a group author in a reference list entry.
• When numerous layers of government agencies are listed as the author of a work, use the most specific agency as the author in the reference. The names of parent agencies appear after the title as the publisher.

Examples of Documents on a Government Website

You are not required to abbreviate the name of a group author, but you can if

• the abbreviation is well-known,
• or if it will help avoid cumbersome repetition,
• or if it will appear at least three times in the paper. 

First Citation

If the group name first appears in the signal phrase in the sentence, include the abbreviation before the year in parentheses, separated with a comma.

If you want to cite an interview, email, chat, text message or other personal communication, you only need to do so as a parenthetical citation in the body of your paper; you do NOT need to include it in your References.

Use this format for the parenthetical citation:

(P. Malone, personal communication, December 3, 2020).

The APA Publication Manual does not provide specific instructions on how to format a PowerPoint presentation; however, many college libraries recommend the following:

• Include the same information on your title slide that you would have on a title page. 
• Include in-text citations for any quote, paraphrase, image, graph, table, data, audio or video file that you use within your presentation. Please note that photographs are considered figures in APA style. See the Figure Setup section of the APA Style & Grammar Guidelines for more information about this.
• The last slide will be your References List. 
• “No citation, permission, or copyright attribution is necessary for clip art from programs like Microsoft Word or PowerPoint” (American Psychological Association [APA], 2020, p. 346).
• Do not reproduce images without permission from the creator or owner of the image. See section 12.15 of the APA manual for more information about this.
