Why cite sources?

Create a trail

Citing sources produces a research trail so that those who read or hear your work can find the same materials you did. When you conduct research for a paper, presentation, or other project, one way you "show your work" is by citing sources. Citing appropriate sources also lends authority and credibility to your arguments.

Avoid plagiarizing

You must cite any quotation, summary, or restatement of any idea or passage from your research. Citing sources is giving credit where credit is due. Not citing sources is plagiarism and can carry severe academic penalties.

Gathering citation information

Whenever you consult a source, record its citation information and note whether you quote (copy passages word-for-word) or you paraphrase (put passages into your own words).

For a book

  • full name(s) of author(s) or editor(s)
  • full title of the book
  • facts of publication: city, publisher, latest copyright date
  • edition name or number, if there's more than one
  • if applicable, name of series, volume number, and total volumes in the series
  • original publication information of any reprinted work
  • if using a specific section (introduction, forward, etc.), title, author, and page numbers of that section
