Goodreads is a free website for book lovers. Imagine it as a large library that you can wander through and see everyone's bookshelves, their reviews and their ratings. You can also post your own reviews and catalog what you have read, are currently reading and plan to read in the future. Don't stop there - join a discussion group, start a book club, contact an author and even post your own writing.

LibraryThing is an online service to help people catalog their books easily. You can access your catalog from anywhere - even your mobile phone. Because everyone catalogs together, LibraryThing also connects people with the same books and comes up with suggestions for what to read next.
