Magical Tomes, Anyone?

My pal Jeremy Tolbert is looking for some help with a supersecret project he’s working on:

I’m working on a little web project that is going to be really fun, but I need titles of magical tomes, both real, historical ones, and invented ones. I’d like to include magical tomes that some of you may have used in your fiction as easter eggs. Just need the titles. Please leave me a comment with the titles and I will work them into the site. Sorry that I am being a bit mysterious, but I want this project to be fun for you too when it’s done and if I tell you about it now, then it won’t be as exciting.

Anyone?
