As it describes itself,

governmentattic.org provides electronic copies of hundreds of interesting Federal Government documents obtained under the Freedom of Information Act.  Fascinating historical documents, reports on items in the news, oddities and fun stuff and government bloopers, they're all here.  Think of browsing this site as rummaging through the Government's Attic — hence our name.

One intriguing category might be called Who's Asked for What?  Search under FOIA Logs.

Also (belated announcement), the once dormant Memory Hole has been back on the case since July.
