The Central Files series contains the general correspondence of the Office of the Vice President from Nelson A. Rockefeller's tenure (December 19, 1974, to January 20, 1977). The series offers partial documentation of Rockefeller's role in the development of national policy and his duties as President of the U.S. Senate. There is correspondence with President Gerald R. Ford and members of his staff, congressional representatives, senators, other government officials, and foreign dignitaries. However, there is very little in this series documenting actual policy formation. Much of the correspondence with government officials concerns the Vice President's information-gathering activities on behalf of the White House and executive agencies, as well as his support of the President's policies. There are also reports and position papers on national issues submitted to the Vice President by individuals both within and outside the federal government. Virtually all of these were unsolicited.
