Series 36 documents Princeton University's involvement in war. From the Revolutionary War's Battle of Princeton, which was fought in part on campus, to the tremendous efforts made by the University during World War II to facilitate training and mobilization, Princeton has been significantly involved in many of America's most momentous wars. Subjects that relate to the military but not necessarily to a particular war, such as the Bronze Memorial Star program, the Reserve Officer Training Corps (ROTC), and the U.S.S. Princeton series of naval vessels are held in this series as well.

This series is mostly comprised of materials related to George F. Kennan's family history. The materials were collected by Kennan's daughter, Joan. Some of the materials were consulted by John Lewis Gaddis as part of his research for his biography of Kennan prior to the materials' transfer to the Mudd Library. The materials in this series are occasionally annotated by either Joan Kennan or John Lewis Gaddis.
