The CIA did release an electronic database called CREST (the CIA Records Search Tool) in 2000, but you could only search document titles and still had to visit the archives to read each document. In 2014, a nonprofit journalism organization called MuckRock filed a Freedom of Information Act (FOIA) lawsuit pressing the CIA to post all of its documents online, but the agency said it would take up to six years to scan everything.
Journalist Michael Best even started a Kickstarter campaign, Buzzfeed points out, to raise funds to manually copy and scan the documents. The CIA finally agreed to post the entire database online last year, and has now made good on that promise.
So, is there anything juicy in there? Not likely. CIA Director of Information Management Joseph Lambert said the agency did one last check through the collection before releasing it, and did not reclassify any more documents.
However, there's no doubt a lot of thrilling stuff for historians, war buffs, UFO enthusiasts and others. The archives cover events from the 1940s the 1990s (each year, a new batch are declassified) and include details about the flight of war criminals from Nazi Germany, the quarter-mile Berlin tunnel built to tap Soviet telephone lines, internal intelligence bulletins and memos from former CIA directors, UFO reports and more.
