When do I need to cite sources in an essay?

All essays written at a university level need to properly cite their sources (with the exception of exams or in-class exercises).

Citations should appear in your essay wherever you quote or paraphrase information from a source. These citations usually correspond to entries in a bibliography or reference list at the end of your essay.

The exact format of your citations depends on which citation style you are instructed to use. The most common styles are APA and MLA.
