Government records from collections at Hoover Library & Archives have recently 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 are released in full, others in part, and some remain classified. As government agencies continue their review, more declassified documents will become available in the future.
The relevant collections are listed below. The declassified materials are generally available at the end of the Online Archive of California finding aids.
