This collection of over 4,635 documents provides a contemporary record of the political, military and paramilitary operations - overt, covert and extra-official - of the largest political scandal since Watergate. Most documents were collected by the staffs of the many official investigating bodies of the scandal (Tower Commission, Senate Select Committees on Intelligence and Secret Military Assistance to Iran and the Nicaraguan Opposition, etc.). They cover the period between the fall 1983 and late 1986, when the official investigations first began. The detailed two volume guide and index includes subject and name indices, a frame by frame catalog, a chronology, a bibliography and glossaries of names, military terms, and organizations.
