Below are a list of some of the most commonly used citation categories and examples of what information should be included in that citation, as well as how the information should be arranged. When you need to cite a source, follow these steps:

  1. Decide to which category your source belongs. Is it a book? Anthology? Online source? Journal article? Etc.?
  2. Collect the necessary information from your source. Sometimes this takes a bit of digging, especially with the online sources.
  3. Arrange the vital information exactly as it appears in the examples, including all styles and punctuation.
  4. Once you have all of your citations written, arrange them in alphabetical order depending on the first word in the citation on a “Reference List” page at very end of your paper.

Below are some examples of reference entries for commonly used source types. For a more extensive list of source types and reference entries, consult the Publication Manual.

EMAIL AND OTHER PERSONAL COMMUNICATION:

Personal communications are not listed in the Reference List, because they do not provide recoverable data. They are cited in-text only in the following format:

(First initial Last name, personal communication, date)

(V.G. Nguyen, personal communication, September 29, 1998).

If you mention the author in the sentence, you do not need to include the author in the citation:

T.K. Lutes claims that rumor of the president’s retirement is only hearsay (personal communication, April 18, 2001).

APA In-text citations

APA in-text citations require three pieces of information: the author’s last name, the year of publication, and the page number. There are two ways to format this information: with a signal phrase and without a signal phrase. APA recommends using a signal phrase more often to provide clarity.

A “signal phrase” introduces a quotation in order to help the reader understand why it is important and how it fits into the rest of the paper. In the first example below, “Villarreal maintains that…” is the signal phrase.

IF THE AUTHOR IS NAMED IN SIGNAL PHRASE:

If the author is named while introducing the quotation, then the year will follow the author’s name in parentheses, and only a page number is necessary in the citation at the end of the sentence. Remember that in APA, every time an author’s name is mentioned, the year of publication is mentioned as well. Put “p.” before the page number.

Quotation:
Villarreal (2004) maintains that “Sociological research on the structural origins of criminal violence has focused almost exclusively on urban settings” (p. 313).

Paraphrase:
According to Stark (1998), sociologists use samples when studying larger populations; they cannot only use techniques from field research (p. 91).

Note that the above source is paraphrased and not quoted. When paraphrasing specific information from a source, that source still must be cited within the paper and in the works cited list.

IF THE AUTHOR IS NOT NAMED IN SIGNAL PHRASE:

If the signal phrase does not mention the author, or if the sentence does not have a signal phrase, all three components will come at the end of the sentence in parentheses. Put commas between the parts, and put “p.” before the page number.

Quotation:
It may be true that “humans will retain that culture which they believe is rewarding” (Stark, 1998, p. 240).

Paraphrase:
One hypothesis is that disputed property rights cause conflict and violence in agrarian communities (Villarreal, 2004, p. 318).

IF A SOURCE HAS MULTIPLE AUTHORS:
For a source with two authors, include both authors’ names in each parenthetical citation or signal phrase. Connect the authors’ names with “and” in signal phrases and with “&” inside parenthetical citations.

Signal phrase:
As Alderson-Day and Fernyhough (2015) note, “[i]nner speech is a paradoxical phenomenon” (p. 957).

No signal phrase:
Inner speech “is central to many people’s everyday lives, and yet it presents considerable challenges to any effort to study it scientifically” (Alderson-Day & Fernyhough, 2015, p. 957).

For a source with three or more authors, include only the first author’s name followed by “et al.” from the first parenthetical citation or signal phrase onward.

No signal phrase:
Effective teams can be difficult to describe because “high performance along one domain does not translate to high performance along another” (Ervin et al., 2018, p. 470).

Signal phrase:
Biebel et al. (2018) noted that “incorporating the voice of students with psychiatric disabilities into supported education services can increase access, involvement, and retention” (p. 299).

IF USING AN INTERNET OR ELECTRONIC SOURCE WITH NO AUTHOR OR PAGE NUMBER:

Author Unknown:
Cite in text the first few words of the reference list entry (usually the title) and the year. Use double quotation marks around the title or abbreviated title.: ("New Child Vaccine," 2001).

Page Number Unknown:
When the pages of a web source are fixed (as in PDF files), supply a page number. Although print-outs from websites sometimes show page numbers, APA recommends treating them as unpaginated and allows the omission of the page number. When the material does not include page numbers, you can include any of the following in the text to cite the quotation (from pp. 273 of the Publication Manual):

  • A heading or section name.
  • A paragraph number, if provided; alternatively, you could count paragraphs down from the beginning of the document: (para. 2).
  • A heading or section name plus a paragraph number within that section.
  • An abbreviated heading in quotation marks, in cases in which the complete heading is too long to cite in full.
