Citations within your text link specific passages to the sources you consulted or quoted. This can be done through in-text parenthetic notes, footnotes, or endnotes. In addition, a bibliography or list of works cited is almost always placed at the end of your paper. The citation system and format you use will be determined by the citation style you choose. Ask your instructor which style sheet he or she wishes you to use and if there are other special formatting instructions you should follow.
