When Do I Need to Document, Cite, and Reference My Sources?

Whenever you use someone else’s words or ideas, you should document, cite, and reference your sources. These three actions clearly credit the work of others, which is the best thing you can do to avoid plagiarism.

Document your Sources

Documentation involves giving credit to a source by making it clear that you borrowed it from someone else. When you document a source, you should name it specifically and also provide complete information on your bibliography page so that others can locate it if they want to.

Following are examples of different types of sources that should be documented:

Example 1: (print source)

Our course textbook, Strategic Marketing Management, identifies strategic decisions and tactical decisions as equally necessary in circumventing price wars.

Chernev, A. (2012). Strategic Marketing Management (7th ed.). Chicago, IL: Cerebellum Press.

Example 2: (electronic source)

According to the National Peanut Board (www.nationalpeanutboard.org), 94% of households in the United States have a jar of peanut butter in the cupboard right now.

Example 3: (image)

Gogh, Vincent van. The Starry Night. 1889. Oil on canvas. 29 in. x 36 ¼ in. Museum of Modern Art, New York.

Example 4: (media)

Human beings were born to learn; all it takes is motivation and perseverance (You Can Learn Anything, 2014).

Example 5: (personal communication)

As incoming first-year students at our own university prepared for the 2010-2011 academic year, 95% planned to bring a laptop computer to campus, and almost 60% planned to bring a hand-held device with WiFi capabilities (L. M. Bradley, personal communication, July 16, 2010).

Cite your Sources

Citation involves specifically crediting sources each time you use them. Both direct quotations and paraphrased ideas should be cited.

A source cited within the body of a paper or project is called an in-text citation. It looks something like this: (Arnett, 2012).

In addition to providing an in-text citation within the body of your work, you should provide complete information about the source on your bibliography page so that others can locate it if they want to.

The format or style used to cite your sources varies by academic discipline. The following examples of in-text citations are in American Psychological Association (APA) Style:

Example 1: (direct quotation)

“Friends provide a bridge between the close attachments young people have to their family members and the close attachment they will eventually have to a romantic partner” (Arnett, 2012, p. 237).

Arnett, J.J. (2012). Adolescence and emerging adulthood: A cultural approach (5th ed.). Upper Saddle River, NJ: Pearson-Prentice Hall.

Example 2: (paraphrase)

Friendships play an important role in adolescent development. They help adolescents transition from the family relationships they experience during childhood to the romantic relationships they will experience in adulthood (Arnett, 2012).

Reference your Sources

A reference is complete information about your source so that others can see what type of source you used (e.g., book, journal article, image, website, etc.) and locate it if they wish to do so. References are typically listed in alphabetical order at the end of a paper or project. The format or style used to reference your sources varies by academic discipline.

The following examples are in Modern Language Association (MLA) style, American Psychological Association (APA) style, and Chicago/Turabian style:

Example 1: (MLA style)

Works Cited
Capote, Truman. In Cold Blood. New York: Vintage International, 1993. Print.

Example 2: (APA style)

Example 3: (Chicago/Turabian style)

You may be confused about the terms Works Cited, References, and Notes in the previous examples. Different citation styles use different terms for referencing sources. Be sure to use the term that is consistent with the citation style you are using.
