Books for Science Olympiad

This is still a work in progress, but I've put up a Science Olympiad account over at Library Thing.

If you're not familar with Library Thing it's an online tool to keep track of books in your library. It's very cool and it's a free service up to 200 books.

For our Science Olympiad team's account, I'm posting books we've used in the past to prepare for competition. I'm hoping that it'll help not only our team but other teams find resources to prepare for competition.

Please feel free to leave comments on books you've found useful.
