WRIT 0020-307 202430 Critical Writing Seminar: Craft Of Prose: Understanding a citation

Elements of a Citation

A source's citation includes the information necessary to identify and retrieve that source, including but not limited to:

  • author name(s)
  • titles of books, articles, and journals
  • date of publication
  • page numbers
  • volume and issue numbers (for articles)

The type of source being cited (books, journals, interviews, blogs, videos, social media, etc.) and the citation style being used will determine what the citation looks like. Choose an appropriate style guide for your needs.  Here is an example of an article citation using four different citation styles:
