CIA Electronic Reading Room
The Central Intelligence Agency (CIA) has digitized thousands of formerly secret documents declassified to comply with Freedom of Information Act requests.
Keyword search capabilities are provided for the complete site. In addition, there are eight collections designated as "frequently requested records" that total nearly 8,000 documents. These collections cover a number of Cold War topics: CIA involvement in the 1954 coup in Guatemala; convicted spies Ethel and Julius Rosenberg; the 1961 Bay of Pigs affair; and two well-known espionage incidents.
Additional topics include POW MIAs in Vietnam, human rights abuses in Latin America, and UFOs. A disclaimer notes that some material cannot be disclosed due to national security laws, and released pages often have material deleted or blacked out. Still, the material offered is voluminous and useful for studying Cold War foreign policy and military history.
