How do you find your books?

Not everyone loves to read but if you do and you want some advice for finding a great book, GoodReads has a top notch network of readers meticulously reviewing and rating thousands of books. They are essentially an online reading club except you don't have to constantly participate to reap the benefits. You can see what any book is rated and how it was reviewed and as you make friends through the site or have your own friends sign up, the ability to find new and recommended books increases dramatically. Think of IMDB's ratings but perfected for books.
