More than fifty-two files of U.S. government records from twenty-five different archival collections at Hoover have been declassified. The collections were created by diplomatic, military, and other government officials.
Since 2001, a government team has been visiting the Hoover Archives to review security-classified records, which are then evaluated by the relevant federal agencies. Some records were released in full, others in part, and some remain classified. The newly declassified records now available are the second set of declassified materials to have been returned to Hoover. As the process continues and government agencies continue their review, more declassified documents will become available, a process that is likely to take years.
The relevant collections are listed below. The declassified materials are generally available at the end of the collection, and will be listed in the descriptions below.
