In April 1995, President Clinton signed an executive order mandating that all secret government documents 25 years old or older, and deemed to be of “historical value,” be released to the public unless federal agencies sought exemptions for specific files that remained sensitive. The order called for the creation of a “government wide database of information that has been declassified” and stated that its contents “shall be available to the public.”

Included in that database are a treasure trove of declassified documents from the CIA.

Now that that database is easily accessible to the public via the Agency’s FOIA (Freedom of Information Act) Electronic Reading Room, we can search a vast archive of historically signficant documents that would have made a cold-war era KGB agent drool.

And what is the number one search term? …

Is it “Bay of Pigs.” Nope.

What about “Kennedy” or “assassination?” Not even close.

How about “nuclear weapons.” Getting even colder.

The top search term in five of the last six months, by a significant margin, is …

… UFO.
