CREST: 25-Year Program Archive

Printer-friendly versionPrinter-friendly version

The automatic declassification provisions of Executive Order 13256 (formerly EO 12958, as amended) require the declassification of nonexempt historically valuable records 25 years or older. The EO was originally issued in April 1995 and via amendment established 31 December 2006 as the first major deadline for automatic declassification under the "25-year program".  By that date, agencies were to have completed the review of all hardcopy documents determined to contain exclusively their equities.  For CIA, the 2006 deadline covered the span of relevant documents originally dating from the establishment of the CIA after WWII through 1981.

The requirement to automatically declassify records 25 years or older "rolls" forward one year at a time.  For example, by 31 December 2012, permanent records through 31 December 1987 were automatically declassified, unless appropriately exempted under the guidelines of the EO.  In this regard, CIA maintains a program operating out of the CIA Declassification Center to review records under the purview of EO 13526 before they reach their automatic declassification deadline.

CREST

Since 2000, CIA has installed and maintained an electronic full-text searchable system, which it has named CREST (the CIA Records Search Tool), at NARA II in College Park, Maryland. The CREST system is the publically 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.

In order to directly access CREST, a researcher must visit the National Archives at College Park, Maryland. CIA recognizes that such visits may be inconvienent and present an obstacle to many researchers. Therefore, this website provides researchers with an online CREST Finding Aid to research the availability of CIA documents declassified and loaded on CREST. In certain cases, as described below, PDF document images are also available.

Title: The title listed will be the formal title of a report or the stated subject of a memorandum. However, the title maybe the best attempt by Agency indexers to identify documents without clear formal titles such as cables, letters, written notes, and other forms of communication and correspondence. In such cases, the title may include reference to the type of document, originator, recipient, location, etc.

Doc No./ESDN: The Electronic Standard Document Number (ESDN) is the internal Agency tracking number which should be used when submitting a FOIA request.

With each rolling year, CIA will continue to release documents on CREST that are 25-years old or older in compliance with the provisions of the Executive Order.

Best of CREST

CIA has begun to include document images in addition to the metadata for a select group of documents referred to as the "Best of CREST" (BOC). BOC document images will be in PDF format (readable through the free Adobe Reader TM software). The BOC collection will be added to periodically. The availability of BOC document images will be clearly indicated in search results by the presence of a PDF icon (underneath the document metadata). BOC is an effort to make CREST documents even more accessible to the public.

FOIA Requests for CREST Documents

Please keep in mind that when you submit a FOIA request for CREST documents, citing the ESDN, you will automatically be charged reproduction costs for documents at ten cents per page beyond the first 100 pages, which are free. Please do not send money in advance, as online page counts are not always accurate. Any reproduction costs applicable will be included at the time documents are sent.
