Shelfari.com is a site that allows users to create virtual shelves of books
for others to see and learn more about you. Shelfari is in the tradition of MySpace as you have to
be a member and the fun is to browse on others' shelves and let others do the same.
Another site of note is booksfree.com which is the sister to Netflix,
only for books. This is a lending library which requires a monthly fee but might be fun to check out.
