Central Intelligence Agency Question:

►Yes. CIA releases millions of pages of documents each year. Much of this is material of historical significance or personal interest that has been declassified under Executive Order 12958 (a presidential order outlining a uniform system for handling national security information) or the Freedom of Information Act (FOIA) and Privacy Act (statutes that give US citizens access to US government information or US government information about themselves, respectively).
►The Agency handles thousands of FOIA cases each year and maintains CIA’s FOIA Electronic Reading Room to release this information to the public and to provide guidance for requesting information. Some released information of significant public interest or historical value is also available at the National Archives and Records Administration. Specific copies of any previously declassified records are available directly from CIA's FOIA office.
