If you're looking to stock your reading list, YourNextRead is a simple and crowd-driven tool for finding out what book you should read next based on the ones you've recently finished.
Tell YourNextRead what book you just finished — and enjoyed! — and it will generate a web of eight related books. You can click on any of the books to learn more about it, which will in turn generate a new web based on that book or you can use the thumbs up/down buttons to agree or disagree with the suggestions YourNextRead gives you.
Each suggestion includes Amazon rankings and ratings and a link to purchase the book on Amazon. You can use the service without logging in but signing up for a free account enables your book-browsing history and the wishlist function. Have a favourite tool for finding new books? Let's hear about it in the comments. Thanks Bill!
