The Subject File is focused on Schlesinger's career in various government and cabinet positions. Appointed by President Richard M. Nixon in 1969 as assistant director of the Bureau of the Budget, later Office of Management and Budget, Schlesinger left the Rand Corporation where he had served as the director of strategic studies working on the strategic analysis of nuclear weaponry, atomic energy issues, and nuclear proliferation. Many of his writings, and a large number of those of his colleagues at the Rand Corporation, traveled with Schlesinger to Washington, D.C., and are part of his Bureau of the Budget files. He apparently used these writings for reference as his new position involved national security issues, scientific and technical programs, and energy policy and its impact on the environment. His main effort was on defense issues. Other items in the Subject File include Schlesinger's speeches and congressional testimony.
