The United States Institute of Peace (USIP) was created by Congress in 1984, following a recommendation by a commission chaired by Hawai`i senator Spark Matsunaga. Its mission is "to increase the nation's capacity to manage international conflict without violence."
Government Documents has a partial collection of USIP publications, including the following series:
United States Institute of Peace in brief (Y 3.P 31:16) Brief publications about conflicts in various parts of the world.
Peaceworks (Y 3.P 31:19) In-depth publications about conflict management in general and in specific countries.
In addition, we have many USIP monographs about peacemaking and conflict resolution.
