The CIA Reading Room's UFOs: Fact or Fiction? collection is the official CIA doorway into UFO-related FOIA records, and the broader CREST archive/search places those declassified records inside the public Electronic Reading Room.12
It matters because CIA moved CREST online in January 2017 after years when the standalone CIA Records Search Tool was only available in person at the National Archives facility in College Park, Maryland; the online release made about 930,000 documents and more than 12 million pages searchable from home.2
The collection and related Reading Room searches surface historical sighting reports, foreign cables, press items, branch-chief meeting minutes, surveys of flying-saucer reports, memoranda to senior officials, and 1953 Scientific Advisory Panel materials that CIA itself highlights for skeptical and believer-oriented reading paths.34
Read the resource as an archive and search layer, not a live UAP reporting channel or a complete federal UFO case database. CIA's own historical account says Agency concern was substantial until the early 1950s and more limited afterward, while Air Force programs such as SIGN, GRUDGE, and BLUE BOOK carried much of the formal investigation record.56
The records are valuable precisely because they preserve how official interest, public pressure, Cold War fears, scientific review, and declassification practice interacted over time; they do not, by themselves, validate any sighting as extraterrestrial or explain every record returned by a keyword search.256
