I read a lot, so I am always trying to find different books to read. I started doing some research to see if there were any sites out there that allowed you to catalog all of your books, get reviews, etc. There were a few top sites on the web. They were Librarything, GoodReads, and Shelfari. It took me a little while to decide which site to use, but after some research (and a lot of negative web information about Shelfari) I chose to try Librarything. It allows you to add all of the books you have read (after 200 you have to pay for an advanced membership), catalog them, review them, get reviews from other readers, discuss authors in forums, etc. For any book junkie the site really is useful.
Check out the little widget on the right side of the site to see 8 random books pulled from my collection. Clicking on them will take you to their Amazon information page. Most of the books in my collection are spy thrillers, but there are some good non-fiction books there as well. Once I get all of my old books out of the closet and cataloged the variety will increase.
