American military, diplomatic, and humanitarian personnel participate in peacekeeping efforts around the world. Now in the fifth revised edition, Peacekeeping: A Selected Bibliography is meant to provide a starting place for research on peacekeeping's expanding role in world affairs. It lists references for readings about peacekeeping in general, highlights special issues and concerns, and addresses past and present operations in the following areas: Africa, Asia and the Pacific, Central and South America, Europe, Russia and the New Independent States, and the Middle East. With the exception of some important older titles, most of the books, documents, articles, and online resources are dated 2004 to the present. Resources listed in this bibliography are all available in the USAWC Library. For your convenience, we have added library call numbers, Internet addresses, or database links at the end of each entry. Web sites were accessed June 2009. For other closely related information, researchers should refer to the Library's Post Conflict Reconstruction: A Selected Bibliography, compiled in January 2007, as well as the Additional Resources section within this bibliography. This bibliography and others, compiled by our research librarians, are available online through the Library's home page at http://www.carlisle.army.mil/library/bibliographies.htm.
