Shelfari is a virtual bookshelf where you can not only share reviews on books that you've read and find reviews on ones you want to read, but can join groups to find different recommendations based on your genre preferences. It's like a virtual bookshelf and book club all in one, and it's kind of cool visually, too. Check it out, I'd recommend it!
Mine is at www.shelfari.com/pinkmacaroons, if you want to be friends.
Good luck on your explication papers!
