MuckRock is a non-profit collaborative news site that gives you the tools to file, track, and share public records requests. Muckrock members have FOILed and FOIAed many subject matter lists. Subject matter lists identify what records are maintained by an agency. You can use these lists (state, federal, municipal) to find out what the record you are looking for is called by that agency, so that your request can be more specific, thereby increasing the chances that it will be fulfilled.
