Even book lovers get their own social networking sites. iLibrarian recently compiled a list of the top 10 websites for book lovers. These sites allow readers worldwide to be active in book groups, get free books, and even keep track of what their friends are reading. I'll confess, even though I'm totally addicted to Goodreads, I hadn't heard of most of these sites.

10. PaperBack Swap- Forget used bookstores. You can your paperbacks, hardbacks, audiobooks, and textbooks with others. The site provides exact postage labels which can be printed out. Once a book is mailed, you can request one for yourself from the cache of over 3 million titles available.
