LBJ Presidential Library - Reading RoomTwo parts of the digital reading room in particular are most interesting to Vietnam researchers. The first is a collection of Johnson’s National Security Action Memorandums, which are presidential directives that relate to national security. The second is a collection of contemporary interviews with key Cold War figures—such as Secretary of State Dean Rusk, Foreign Policy Adviser Walt Rostow, and Defense Secretary Robert McNamara—which are helpful to understanding the war from the administration’s perspective.
