ABSTRACT
This chapter reviews some general rules about what to cite and two of the most commonly used systems in international relations research papers: the Turabian and American Psychological Association (APA) styles. A paper that lacks citations will have little credibility and will raise questions of plagiarism and sloppy research. In general, deciding what needs a citation and what does not is a relatively easy task. In general, it is not necessary to provide a citation for data and statistics that are common knowledge or for data and statistics that are not considered subject to change or interpretation. Newspaper charts and graphs often use data from a variety of sources. Because you will not know which data came from what source, one need to provide a reference for the information found in the newspaper.
