Citing Sources: What is a Citation?

What is a Citation or Reference?

A citation or reference is a short description of a resource that is used in a paper or project.  Whenever you refer to an idea that is not originally yours, or quote someone else's work, you must give credit to the originator by citing that source in your paper.  You should also provide documentation for any facts or figures you use that are not common knowledge.  All the sources you use will be compiled into a list at the end of your paper.  This is called a Bibliography, Reference List, or a Works Cited.

Parts of a Citation

A citation or reference includes all the information needed for someone to identify and find the source. There are 4 main parts to every citation:  Author, Date, Title, & Location.  Depending on the citation style, a citation may include any of the following: title, author, date, page numbers, publisher, place of publication, etc.

  • Chicago/Turabian
  • MLA (Modern Language Association)
