United States Supreme Court decision from 1893 (www.findlaw.com/casecode/supreme.htm). Have you ever had the situation where you found a website with great links and then one day the link you liked the best just disappeared? Actually that happens all the time but one great website that that happened to is United States Supreme Court decisions from 1893.
GPO Access (www.gpo.gov/fdsys). What I suspect happened is that a group of people in federal land got together and said, "hey, why don't we gather everything together that is federal related and put it on one website. Then, when people get comfortable and know how to use it, we'll yank it out from under them, remove it entirely from the web, and really mess with their heads. Well, they've got the first part right - I'm just waiting for them to turn it off. Until "they" do, go forth and search all things Federal.
So, next time you're out and about the World Wide Web, know that while most things aren't free - some are and if you want/need to know where to find what's what and where, the person you need to talk to is your friendly neighborhood law librarian ('cause if we can't find it, odds are it can't be found).
