Citation Help

Provides information to help you cite sources correctly in different citation styles.

Why Cite?

  • Webpages expire, books and articles get lost, photographs and films degrade. Citations are necessary in order to assure that the next person would be able to access the same information through different means.
  • Citing is also important for credibility and building on research. You may have a good idea, but simply stating it does not make it true or believable. Give your ideas validity and support by citing established authors.
  • To avoid plagiarism - nothing is worse to an author than discovering their hard work has been stolen and claimed as original by someone else. Citations give authors their due credit.

Additional Help

Hopefully the information in this guide will help you with citing sources correctly, but if you feel you need additional help, the Writing Center at Purdue has an extensive tutorial on APA and MLA citation styles.  Check out their Online Writing Lab (OWL).


An additional source of information is the Excelsior Online Writing Lab, which provides extensive information on the writing process, evaluating research, and informational tutorials on building citations in APA, MLA, and Chicago style(s).
