Scott Armstrong launched the National Security Archive in 1985 while standing in Washington, D.C. The organization operates as a non-profit research institution located on the George Washington University campus.
The archive holds the largest repository of declassified U.S. documents outside the federal government and has released more than 15 million pages of government documents over four decades. Key releases include the CIA's Family Jewels list, an NSA watch list containing names of 1,600 Americans, and a President's Daily Brief from the 6th of August 2001 warning about Osama bin Laden.
Litigation efforts by the National Security Archive resulted in preserving over a billion emails and electronic messages from the White House. These legal actions recovered more than 30 million messages from the 1980s and 1990s plus over 22 million deleted messages between March 2003 and October 2005.
The National Security Archive relies on publication revenues and grants from private foundations for its three million dollar yearly budget since it receives no government funding. Major donors include the Carnegie Corporation of New York, the Ford Foundation, the William and Flora Hewlett Foundation, and the John D. and Catherine T. MacArthur Foundation.
The archive shared the George Foster Peabody Award in 1998 and won the George Polk Award in 1999 for facilitating searches for journalists and scholars. Staff members have authored over 100 books including winners of the 1996 Pulitzer Prize and the 1995 National Book Award while the organization secured the 1996 Lionel Gelber Prize and the 1996 James Madison Award Citation.
