U.S. Declassified Documents Online

Classified documents are items the United States Federal Government has deemed confidential because distribution of their contents might compromise national security. The three levels of classified documents are confidential, Secret, and Top Secret. However, the passage of the Freedom of Information Act in 1967 guarantees the public access to these federal government files. From use of the Act, the public is able to access such specific classified documents as: governmental correspondences, memoranda, cabinet minutes, national security policy statements, intelligence reports, and technical studies. Subject topics fall into the typically assumed classified genres: Castro and Cuba, the Kennedy assassinations, Krushchev, Roswell, and Vietnam, to name a few.

Since 1982, Primary Source Media (PSM) has published the Declassified Documents. This unique reference product involves indexing, abstracting, and capturing on microfiche a large selection of U.S. government documents from presidential libraries. These libraries receive declassified documents from various government agencies, including the White House, the CIA, the FBI, the State Department, and others. As researchers request documents, the libraries photocopy and provide them to PSM for filming. The result is a collection of over 75,000 documents that has been built by researchers for nearly two decades. In 1998, the systematic digitization and online publication of the Declassified Documents was initiated, and the text of every page of every document in the collection has been digitally scanned and captured, and is now available full-text online.

 

Access:

The University of Oklahoma Government Documents Collection initially subscribed to the paper and microfiche version of the Declassified Documents Index. This set runs from 1945-2004. In 2005, University Libraries acquired access to the internet version of the database. OU Government Documents is the only institution in the state to have the full indexing and microfiche collection, as well as internet access to the Declassified Documents set.
