PBHL1100: Healthy U: Citing Sources

Why do I need to cite?

You must cite your source of information any time you use another person’s ideas, opinion or theory. You must also provide citations for any facts, statistics, graphs, or drawings that are not common knowledge. Quotations of another person's actual spoken or written word and paraphrases of another person's spoken or written words must also be cited.

For additional information about citing sources and avoiding plagiarism, please visit Purdue University's Online Writing Lab
