War and Conflict Research Resources

Below are links to databases and electronic resources that support the study of international conflict and war and related areas of research.


Handbooks are useful for obtaining background information about contemporary theories, concepts, issues, events, or topics and for understanding how scholars have debated a specific area of study. These handbooks are available either electronically and/or located on the book shelves in the Medicine Crow Center Library for International and Public Affairs.
