Citation Guides

What’s a citation?

A citation is a way of giving credit to individuals for their creative and intellectual works. It directs readers to the sources you consulted for your research and helps to avoid plagiarism.

When to cite?

Always cite your sources when you’re directly quoting, summarizing, or paraphrasing someone else’s work. If it’s your own idea, it doesn’t need a citation.

Citation styles by subject

Disciplines and subjects typically use a specific citation style. It’s important to clarify the preferred citation style with each instructor to ensure you’re using the best one.

  • APA: Education, Journalism, Nursing, Psychology, Social Sciences, Sciences, etc.
  • Chicago/Turabian: Business, History, Humanities, Fine Arts, etc.
  • MLA: Arts and Humanities (i.e. English, Art History, Philosophy, Music, Religion, Language, Linguistics, etc.)
