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.
