I put together a Basics of Copyright post for scans_daily a while back; you're welcome to use any of it that's useful. There's also nifty links in the comments.

The "copyfight" folder on my C drive is over 750mb. (Includes collections, like "every pdf filed for or against the Googlebooks settlement.") If you're looking for anything more specific than "send me copyright stuff links," I'd be happy to help. (I'd be happy to help with "copyright stuff links" too, but that can get overwhelming fast.)
