Find how to cite sources and properly format your paper in ALA, MLA, and Chicago styles.

What is a Citation?

The Credible Hulk always cites his sources.

A citation is what tells your reader that you got information from another source.  It is used to prevent plagarism, recognize another author's work, and make sure that you are using accurate information.

All of your citations will be listed on a References (APA) or Works Cited (MLA) page at the end of your paper.  These are the two most common citation formats used.  To learn how to use either of these formats for your list of references, click on the tabs above.

Plagiarism Resources


There are several different ways to cite resources in your paper, most of which have been standardized and approved by professional or educational organizations.  The citation style usually depends on the academic discipline involved. For example:

  • MLA style is typically used by the Humanities (Art, Literature, Music, Philosophy, and Religion).
  • APA style is often used by Business, Law and the Social Sciences (Education, Psychology, Sociology).
  • Chicago/Turabian is generally used by History and some of the Fine Arts.
  • CSE style is used by most of the Sciences (Biology, Chemistry, Geology, Mathematics, and Nursing).

IMPORTANT: Check with your instructor to make sure you use the style they require. And whatever style you choose, BE CONSISTENT!
