Bridge - Introduction to Library Reseach

Why do we cite?

There are many reasons why it is so important to cite the sources you use in your research.

  • You demonstrate to your reader you've done proper research by listing sources you used to get your information.
  • You avoid plagiarism by quoting the words and ideas of other scholars.
  • You are being a responsible scholar by giving credit to other researchers and acknowledging their ideas.
  • You allow your reader to find the sources you used by citing them accurately in your paper by using in-text citations or footnotes in combination with a bibliography or works cited list.

When should you cite your sources?

According to the IU Indianapolis Code of Student Rights, Responsibilities, and Conduct, "a student must give credit to the originality of others and acknowledge indebtedness whenever:

  1. Directly quoting another person’s actual words, whether oral or written;
  2. Using another person’s ideas, opinions, or theories;
  3. Paraphrasing the words, ideas, opinions, or theories of others, whether oral or written;
  4. Borrowing facts, statistics, or illustrative material; or
  5. Offering materials assembled or collected by others in the form of projects or collections without acknowledgment."

Citing Your Sources

There are many different "styles" you may choose from when citing sources. Your professor will probably tell you which "style" is preferred for your class. MLA (Modern Language Association), Chicago, and APA (American Psychological Association) are three of the most commonly used citation styles, but there are hundreds.

Recent editions of style manuals, which include detailed information and examples, are available at the Services & Information Desk at the University Library. If you need help on your research project, please contact a subject specialist librarian.

We have the Chicago Manual of Style available online as well as in print. For quick reference, there are many online sources. One of the best is the Purdue OWL. But be aware that the manual is always the most authoritative source.
