Library Thing is an online service to help people catalog their books easily. You can access your catalog from anywhere—even on your mobile phone. Because everyone catalogs together, Library Thing also connects people with the same books, comes up with suggestions for what to read next, and so forth.
In addition to cataloging books, it does much more. Among some of its services, it is a social networking space, an online catalog, a blog spot for book discovery and recommendations, and a community of groups like 75 Books Challenge, The Green Dragon, and Folio Society Devotees. There is also a mobile version of Library Thing.
Goodreads is a "social cataloging" website that allows individuals to freely search its database of books, annotations, and reviews. Users can sign up and register books to generate library catalogs and reading lists. They can also create their own groups of book suggestions, surveys, polls, blogs, and discussions.
