Citation and Reference Styles

We expect that the text and graphics you submit as part of your assignments are original. We reserve the right to use the plagiarism detection service Turnitin.com to assure the originality of course assignments. You may build upon ideas, words, and illustrations produced by others, but you must acknowledge such contributions formally. Unacknowledged contributions are considered to be plagiarized. This guide explains when and how you should acknowledge the contributions of others to your own work.

Different disciplines adopt different standards for citations and references. Moreover, almost every professional publication enforces its own variation on the standard styles. The most widely used styles include:

So, which one should I use?

Just as each discipline adopts different standards, each instructor and/or course may require you to use a different citation style. Please refer to the syllabus to learn what standard you will be expected to comply with. If it is not listed there, do not hesitate to contact your instructor.

Regardless of the style you use, we do expect two things:

  1. Whenever you include text, a graphic, or an idea that is not your own, acknowledge the contribution so that readers can find the original source.
  2. Consistently apply one style of citations and references for all of your assignments.
