The National Archives and Records Administration released today a complete digital version of the United States-Vietnam Relations, 1945-1967: A Study Prepared by The Department of Defense, better know as the Pentagon Papers. (see http://www.archives.gov/research/pentagon-papers/) The document was produced in the later 1960s at the order of then Secretary of Defense Robert McNamara. Commissioned in 1967 and completed in 1969, without the knowledge of President Johnson, the Pentagon Papers were meant to be a briefing document for internal use only in the Defense Department.
