Shelfari

If you are into books and sharing your thoughts about them, whether that is by book reviews, lists, what you own, etc, then Shelfari may be a social network for you. I am on Shelfari and I am using it to catalogue my entire library (both hard copy and digital) – it will take me a while to complete the exercise. You can embed your bookshelf into your website, start a book group and share with others within the Shelfari community, plus much more. Well worth a look.
