The Harry S. Truman Library initiated a series of oral history interviews with key officials of the Truman Administration. The interviews were carried out by personnel from the Library including the Director Philip C. Brookes and Jerry N. Mess, or by other academics on the Library's behalf, such as Theodore A. Wilson and Richard D. McKinzie. Most of the documents in this unit are excerpts taken from longer units and thus relate only to Jean Monnet and aspects of European integration.

The originals are held in various Archives and Presidential Libraries in the USA
