The Digital National Security Archive currently hosts 35,000 declassified documents, comprising 15 distinct collections on U.S. security policies and decision making. For example, you may access documents from the Cuban Missle Crisis, Iran-Contra Affair, and Presidential Directives on National Security from Truman to Clinton. There is also a Documents of the Month section, and the site indicates that new document collections will be added annually. The site is sponsored by the National Security Archive (George Washington University) and ProQuest Information and Learning Company. (Via Internet Scout Weblog)
