Citation Styles

Guide for APA, Chicago, MLA citation styles and more.

Citation styles are sets of rules for properly attributing source material in your academic work. Different disciplines tend to use different citation styles. For example:

  • MLA style is typically used by the Humanities
  • APA style is often used by Education, Psychology, and Business.
  • Chicago/Turabian is generally used by History and some of the Fine Arts

Why do we cite?

  • To give credit:
    • Properly attribute intellectual property to the creator.
    • Avoid consequences of plagiarism and violating the academic honor code.
  • To enhance your credibility as a scholar:
    • Provide evidence in support of your argument.
    • Demonstrate that you are knowledgeable on a particular topic.
    • Refute a potential counter-argument.
  • To establish shared understanding: 
    • Provide your audience with helpful background information.

When do we cite?

  • Every time you use content that you did not create
  • For example: 
    • direct quotes: copy and paste of what someone else has said or written.
    • paraphrases: when you take 1-2 sentences from a source and put them in your own words (still requires an in-text citation).

How do we cite?

How exactly you cite your sources will depend on the citation style you are using.

However, all citation styles have two components: 

  1. An in-text citation: some kind of indication in the body of your work that tells your audience exactly when you are referencing source material. For instance, in MLA and APA style, the in-text citation is a parenthetical. For example: (Smith, 1999) or (Smith 23). 
  2. A complete citation entry: all of the publication information for a particular source. Complete citation entries are like addresses for your sources; they will appear in your Works Cited, References, Footnotes, or Bibliography. 

The in-text citation and your citation entry work in tandem to signal to your audience that you are citing a source and to give them all the information they need to locate the source for themselves.
