The material in this collection covers John Camp's service as director of the agricultural program in Paraguay and Venezuela in the Office of the Coordinator of Inter-American Affairs (1943-1946); representative of the International Basic Economy Corporation (IBEC) in Venezuela (1947-1960); representative in Venezuela (1947-1963), vice-president (1955-1960), and executive vice-president (1961-1969) of the American International Association for Economic and Social Development (AIA); and as consultant (1969-1980) for Nelson Aldrich Rockefeller's 'Michigan Hill' Project, John D. Rockefeller's birthplace, in Tioga County, New York.

This series contains a portion of Governor Nelson A. Rockefeller's political correspondence on state and national issues. The correspondence reflects his role as a national political figure and was filed separately from correspondence generated while serving as Governor of New York.

This series is made up of Nelson A. Rockefeller's personal copies of correspondence, reports, and other documents gathered during his service in the federal government in ten presidential appointments between 1940 and 1969. All manner of documents can be found in these files, from handwritten notes to printed reports. Marginal notes found in Rockefeller's handwriting are not uncommon. These records both duplicate and complement official government records held in the National Archives and in presidential libraries.
