Because I was so pissed off at not being able to find a book the other week, I have started on the Great Library Reorganization of 2006. I have chosen the most arbitrary of organization systems: alphabetization by author's last name. I would prefer a more esoteric system (such as by subject matter) but screw that, I'm going for arbitrary order in my booky universe. Some of the shelf pairings are amusing. I will amuse you with them when I get the gumption. (I'm only bout a 1/8th way through the library, I think.)
I've also diligently been entering the books into the librarything goobersmack.
