Is there a nice book manager for Facebook?

This is the one I use and I really like it: http://apps.facebook.com/imreading/. You can rate the books and review them as well.

i use one called weRead which has a virtual bookshelf where you can mark books as read, want to read, etc and rate/review them

Wow, both of those look great thanks!

I haven’t played much with the iRead applications, but I can tell you unequivocally that LibraryThing.com will suit your purposes and more. It totally expanded my horizons in terms of the data you can glean from cataloging books.

The iRead apps and Library thing are very good! Either one or all!

@drdoombot @ShanEnri Librarything looks wonderful. I will try it out. Thanks!

I use http://books.livingsocial.com on Facebook. If you’re searching for it in Facebook apps, it is called “Visual Bookshelf”. It has its problems (for instance, it doesn’t handle different versions of the same book nearly as well as LibraryThing or Goodreads.com), BUT is is well-integrated with Facebook, it has a lot of users on Facebook already, and the interface is very simple to use. As a heavy reader, I prefer Goodreads.com, but as a human being trying to share my reading experiences with my existing friends, I prefer Visual Bookshelf.
