Since I love it that much, I’ll have to recommend it! It’s such a powerful tool. Some of my private books are displayed in this virtual library. This library is accessible to my students, so that they can browse through their professor’s library in order to talk about various books. They can also write online recensions. Massive!
LibraryThing 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, LibraryThing also connects people with the same books, comes up with suggestions for what to read next, and so forth.
