I've only poked at this briefly (so far!) but it seems like a great idea, so I'll definitely be poking more.
The one bit of feedback I have so far, though, is that the list isn't actually alphabetical... at least, not in the sense the term is usually used in dealing with books. You have, for example, "A Christmas Carol" listed under A, when instead it should be under C. Makes it hard to find things!
Other than that, looks good so far, keep up the good work!
