Executive Order 12937
Declassification of Selected Records Within the National Archives of the United States
This executive order declassifies approximately 43.9 million pages of historical records in the National Archives, spanning World War II-era military and intelligence documents through post-1945 collections including Vietnam War records. The Archivist must make these records available for public research within 30 days, except for specific information that agency heads and the Archivist determine must be protected under non-national-security FOIA exemptions.
