Robert Dallek, Franklin D. Roosevelt and American Foreign Policy, 1932–1945 (New York, 1979), the only complete account of Roosevelt's foreign policies, is an unusually thorough and intelligent work. John Morton Blum, From the Morgenthau Diaries, 3 vols. (Boston, 1959–1967), a meticulous history of the Roosevelt years from the perspective of the Treasury Department, is particularly informative about foreign economic policy.
