Inventorying the FBI
An project to take inventory of the FBI’s files on different subjects in order to identify what the FBI has worked on and to help requesters know what files they can request. This project takes advantage of the FBI’s numerical filing system to query files and identify the subject of a file without having to pay for the complete duplication cost.
The project will begin and initially focus on 161 files, which are Special Inquiries for White House, Congressional Committees and Other Government Agencies and 190 files, which are files relating to the Freedom of Information and Privacy Acts.
That doesn’t mean you can’t contribute by helping ID files of other subjects. For a fairly complete list of the FBI’s file types, see here.
