CREST: 25-Year Program Archive
Since 2000, CIA has installed and maintained an electronic full-text searchable system named CREST (the CIA Records Search Tool), at NARA II in College Park, Maryland. The CREST system is the publicly accessible repository of the subset of CIA records reviewed under the 25-year program in electronic format (manually reviewed and released records are accessioned directly into the National Archives in their original format). Over 11 million pages have been released in electronic format and reside on the CREST database, from which researchers have printed about 1.1 million pages.
Previously, in order to directly access CREST, a researcher was required to visit the National Archives at College Park, Maryland. CIA recognized that such visits were inconvenient and presented an obstacle to many researchers. Therefore, in January 2017, the CIA published the records of the CREST collection online.
