Political science is a wide-ranging field with a number of significant subfields, including American Politics, Comparative Politics, International Relations, and Political Theory. There is great variation even within these subfields. For example, scholars in the subfield of International Relations may have interests in war, international organizations, trade (or more broadly, international political economy), ethnic conflict, and/or diplomacy. Political science also has many overlaps with a number of other disciplines, including sociology (e.g., nationalism and social class), economics (e.g., comparative/international political economy), and law (e.g., international law).
The following list is a sampling of possible sources for locating background information and additional sources as well as building a search vocabulary in the discipline. A good one way to locate additional sources is to browse titles in the same general area, both in the Reference collection and in the Stacks.
