On June 26, 2007 the Central Intelligence Agency released two sets of previously classified historical documents.
The first collection referred to as the “Family Jewels,” consists of nearly 700 pages of documents compiled in 1973 under Director of Central Intelligence James Schlesinger, who asked CIA employees to report activities they thought might be inconsistent with the Agency’s charter.
The second collection, the CAESAR-POLO-ESAU papers, studies twenty years of Soviet and Chinese leadership hierarchies between 1953 and 1973.
The document collections are made publicly available under the Freedom of Information Act (FOIA) and can be found at the CIA’s Freedom of Information Act Electronic Reading Room. Another interesting feature of the CIA Reading Room is the “Frequently Requested Records” section which ranks the top most requested documents from the previous month.
