Plagiarism & Writing with Sources: Citation Styles

Citation Styles

Citation styles provide rules for formatting your citations or references.

There are many different citation styles. The best known are American Psychological Association style (APA), Modern Language Association style (MLA), and Chicago/Turabian style.

Each academic discipline generally requires a particular citation style. If a citation style is not indicated on a course outline or the assignment instructions, ask your instructor which style you should use. 

You can find the COD Library Citing Sources guide at

  • Author
  • Publication Date
  • Publisher or source
  • Start and end pages (for articles and book chapters)

  • The date you accessed the site
  • The digital object identifier (doi) if there is one
  • The URL (web address) if there is not doi
