If bạn are an avid reader like me (I'm bookaholic) certainly you'll enjoy these places.
The Shelfari is the best place to hiển thị off my books, the favorites, the owned, the wish, the must read ones, etc. There are interesting groups and bạn can connect with people all around the world just like you. The shelfs can be displayed in your blogs, journals hoặc sites.And it's all for free.

The thư viện Thing is a very good site too, but for free bạn can catalog only 200 books. In the order hand, thư viện Thing have a great BookSuggest searching that can recommend bạn a book from a book that bạn already read. It's very helpful.
