There is a new site out now called Shelfari:
http://www.shelfari.com/ In which you add the books that you have read to virtual book shelf. Then it matches the books you have read with others in the site that have also read that book and you can look at what is on their shelf. I find it a great way to find out books that I have never heard of before. The following comes directly from the site and explains what "Shelfari" is all about
:
"Welcome to Shelfari!
Books are such a powerful medium. Sometimes with all of the technology that has come in the last century it is easy to forget how revolutionary the printing press was. Books are not going away and Shelfari is here to make your experience with books even better!!
Why do I love Shelfari? I love it for three reasons.
You are what you read!
Express yourself through your book collection! Why just show off the books you identify with in your living room when you can post them on-line for all your friends to see them when they want too!
Listen to your friends!
Most of us buy a book because someone we know recommends it to us. Shelfari makes this easier by linking you with your friends and their bookshelves on the Internet. All done on your own time whenever you feel like exploring the world of books.
A good book demands a Response!
Love it. Hate it. Books are crying for two way interactivity. Shelfari is a great place to rant and rave about why you couldn't put a book down. Or if you can do the world a service and save your friends from wasting their time!
Happy Reading!"
Check it out, its a pretty cool site!
