Since the material in the research paper comes largely from the work of others, it is important to give proper credit by citing the sources used. Cite your sources in a formal manner as you write your paper. The purpose of parenthetical citations is to refer the reader, and give credit to the original source when you use another’s words, ideas, opinions, studies, or facts. Develop a works cited page at the end of the paper to alphabetically list all the sources that you cited. The basic elements of each citation include enough information for a reader to find the original source.
