Turn yesterday's U.S. government secrets into today's new research
U.S. Declassified Documents Online's greatest value lies in the wealth of facts and insights that it provides in connection with the political, economic, and social conditions of the United States and other countries. Materials as diverse as State Department political analyses, White House confidential file materials, National Security Council policy statements, CIA intelligence memoranda, and much more offer unique insights into the inner workings of the US government and world events in the twentieth and twenty-first centuries.
A significant resource for researchers in almost every discipline, this collection makes it possible for researchers to easily and quickly access and review selected previously classified government documents online.
Documents contained in U.S. Declassified Documents Online come from collection editors who actively monitor the release of formerly classified documents from presidential libraries as well as numerous major releases of declassified documents from the Atomic Energy Commission, Central Intelligence Agency (CIA), Department of Defense, Department of Justice, Department of State, Federal Bureau of Investigation (FBI), National Security Council, White House, and other executive agencies. Because the majority of the documents are presidential records and all of them were formerly classified, these records provide a unique, behind-the-scenes view of the highest level of American policy-making on the most sensitive issues of national security and foreign policy.
From many perspectives, this collection illuminates such events and developments as the recognition of the economic and strategic importance of the Middle East, the development of the Cold War and Soviet expansionism, the problem of refugees and displaced persons, the various faces and responses to the end of colonialism in Africa, the economic and social stratification of Latin America, the "miracle" of Western Europe following the devastation and economic collapse of the immediate postwar period, and the application of the "domino theory" in Asia.
The search-and-discovery interface for the collection allows researchers to locate the full text of documents and quickly filter their search results by document type, issue date, source institution, classification level, and date declassified as well as other document characteristics.
