Citing Sources

Guide to citing sources in APA, MLA, ASA, and Vancouver/NLM.

Citing Sources

Why Cite Sources?

You get your research assignment from your professor and they require that you cite your sources. Maybe they want you to use APA or MLA, or some other style like Chicago or Vancouver. What does this really mean? 

Citing your sources...

  • Adds to your credibility and supports your ideas
  • Helps your reader find the sources you reference to read for themselves
  • Ensures the accuracy of scientific and scholarly knowledge
  • Protects and acknowledges intellectual property rights

When should you cite? 

  • Direct Quotations: When you use the author’s exact words
  • Paraphrasing: When you summarize someone else’s words or ideas
  • Facts: When you mention something that is not common knowledge
  • Images: When you use pictures, charts, and graphics that someone else created in a presentation 

Citation Styles

Citation Styles

All academic disciplines use citations, but, they don't all make them the same way. Different citation styles have basically the same information in them, but different disciplines care about different things or use certain materials more frequently. 

Three of the most commonly used citations styles are...

1. MLA: Used in English and other Humanities classes

2. APA: Used in the Natural, Health, and Social Sciences

3. Chicago/Turbian: Used in History and Journalism 

Check out the different citation styles below! Each piece of the citation uses the same color to illustrate that citations are different ways of organizes and formatting the same pieces.
