Shelfari is a social networking community of book lovers. If you are a book lover and not a member of the group, you can log in by visiting the site http://www.shelfari.com.
Here is a line from the last email notice I got from them. This tells it all. “Better than Starbucks… if you like good coffee, great books, sharp wit, and people who read Shakespeare, Dickens, Twain, Marquez, Morrison, Joyce, Faulkner, Cather, Kingsolver and a few hundred other really delicious writers, not to impress strangers, but because they love a good read, then please join us.”
