To avoid the potential for plagiarism, a good rule of thumb is to provide a citation for any idea that is not your own. This includes:
You do not need to cite widely-accepted common knowledge (e.g. "George Washington was the first President of the United States."), proverbs, or common phrases unless you are using a direct quotation.
When in doubt, avoid the possibility of plagiarism and cite your source.
> Written or spoken words, phrases, or sentences from any source, used without proper documentation.
> Summarizing without proper documentation (usually a citation) ideas from another source (unless such information is recognized as common knowledge).
> Facts, statistics, graphs, pictorial representations, or phrases without acknowledging the source (unless such information is recognized as common knowledge).
> Submitting work simultaneously presented in two courses, unless permission is granted by the both the instructors.
> Submitting work, either in whole or in part, created by a professional service and used without attribution (e.g., paper, speech, bibliography, or photograph).
There are several accepted ways to cite the resource you used to write your paper. If you are wondering which to use, ask your professor. The library also has copies of the style manual, a book that gives detailed instructions on how to cite references.
Ask the Information Desk for copies to use in the library. You can also click links to guides listed below.
