Citing Sources Within Your Text

  • Use parenthetical citation with the author's last name and year of publication just next to the material that you are citing.

    Example: (Smith, 2000).

  • If you already mention the author's name in your text, simply provide the year.

    Example: Shimoney (2009) presents two variations of Bell's Theorem...

  • If there is no author, provide the first few words of the title (use parentheses for articles or chapters of books and italics for titles of books) and the year.

    Example: ("Behavioral Genetics," n.d.)

  • If you are using a direct quotation, include the page number (where available) after the quote.

    Example: Campbell & Campbell (2006) concluded that "one of the strongest predictors of Western diseases was blood cholesterol" (p. 77).

  • If two or more sources are listed in the same citation, separate them with a semicolon.

    Example: (Campbell & Campbell, 2006; Catalano & Pickett, 2000)

  • If a source has 3, 4 or 5 authors, list them all the first time you cite them. Each time after that, list the name of the first author followed by et al.

    Example: (Foster, Gal, Murphy, Port & Schmidt, 1997) becomes (Foster et al., 1997) after the first in-text citation.

  • Online and print sources are cited the same way.

Example Text:

(the text below is taken from: Ercegovac, Z., & Richardson, J. V., Jr. (2004) Academic dishonesty, plagiarism included, in the digital age: A literature review. College & Research Libraries, 65, 301-18. Some of the citations have been changed for illustrative purposes.)

For example, in the chapter titled "Youth: Changing Beliefs and Behavior" in The State of Americans, (Bronfenbrenner, McClelland, Wethington, Moen, & Ceci, 1996), it is said that 58.3 percent of high school students let someone else copy their work in 1969 and 97.5 percent did so in 1989. Moreover, the percentage of students who report ever using a cheat sheet doubled from 34 to 68 percent. Surprisingly, nearly 90 percent of college students "strongly agree or somewhat agree" that it is wrong to "hand in someone else's writing as one's own," to "use the Internet to copy text to hand in as one's own," and to "purchase papers from print term-paper mills" (Scanlon & Neumann, 2002, p. 379).

Kibler (1993) reviewed literature that demonstrates that various forms of academic dishonesty have been with us since ancient civilizations and that academic dishonesty, for a variety of reasons, has increased. In his Plagiarism Handbook, Harris (2001) noted that a "free-term-paper site, run by a 16-year-old, receives 13,000 hits a day" (p. 184). Harris gave an example of a librarian who studied plagiarism herself and could not order a paper from a paper mill because the site was "flooded with 800 orders a day" (p. 196). His book marshals lively instructional cartoons that could be used in teaching and discussing the subject of plagiarism.
