There are lots of social networking sites on the Internet – MySpace, Facebook, etc. Some social networking sites rely on a common interest to generate users. Of those, a few are perfect for expanding your library’s presence on the Internet. Shelfari allows users to create bookshelves and add friends through a shared interest in specific books (see the BCLS list). LibraryThing is another site that does the same thing (see another list).
