Digital National Security Archive
The Digital National Security Archive (DNSA) is from the National Security Archive, a non-profit research institute and library located at The George Washington University in Washington, D.C. The NSA has used the U.S. Freedom of Information Act (FOIA) to obtain almost half a million pages, 61 thousand documents, on national security issues. These documents, primary research material on public policy, are digitally scanned and searchable. Some of the scanned documents are complete with the "Classified" stamp overstamped with "Declassified;" some have sensitive information blacked out. DNSA also provides good background material, explaining the context of the documents.
Documents are organized in collections, ranging from "Afghanistan: The Making of U.S. Policy, 1973-1990" to "The Kissinger Transcripts: A Verbatim Record of U.S. Diplomacy, 1969-1977." Also notable are collections on "The Cuban Missile Crisis, 1962," "Terrorism and U.S. Policy, 1968-2002," and "Presidential Directives on National Security from Harry Truman to George W. Bush."
For an interesting search, type in "September 11 attacks (2001)" and browse the results. Fascinating!
