What are citations?

A citation is a reference to an item that gives enough information in order for you to identify it and to be able to find it again.

Generally, citations include four elements:

  1. Author
  2. Title
  3. Source
  4. Date 

The source information is the clue to figuring out what kind of resource the citation points to:

  • For a book, the source information will be a place of publication and a publisher.
  • For an article, the source information will be the journal title, the volume and issue numbers and the page numbers.
  • For a website, the source information will be the URL (which normally begins http://).

Other types of publications (audio/visual materials, government documents, dissertations, etc.) will generally include the basic four elements, but will also include enough information in order for the person reading the citation to identify both the type of information source, as well as how to find the information again.


"Broadly, a citation is a reference to a published or unpublished source (not always the original source).

A prime purpose of a citation is intellectual honesty: to attribute prior or unoriginal work and ideas to the correct sources, and to allow the reader to determine independently whether the referenced material supports the author's argument in the claimed way."
