When someone's obituary appears in the New York Times, FOIA The Dead sends automated requests to the FBI for their records on the recently departed, and publishes the results. So far it has almost 4,000 pages of (sometimes-mundane, sometimes-fascinating) records on 55 people which probably wouldn't have been released otherwise.
