During your studies, you will probably take courses that are similar to one another in subject matter. A point you made in a previous paper may support one of your arguments in a new paper. Just like any other source, these previously written essays must be properly referenced within your paragraphs and cited in a works cited or bibliography.
Determine the style of citation your instructor wants you to use for your current essay. Citation styles vary across disciplines. If you are writing an English paper, you might be expected to form citations using the Modern Language Association style. If you are writing a history paper, you might be expected to use the Chicago citation method. The instructor normally lists this requirement on your assignment sheet. Contact your instructor if it is not listed, or if his wishes are ambiguous.

Medium of the paper (for example, print).
