Goodreads is not only a fine place to find your next "good read," but also a great way to keep track of books you've enjoyed. Visitors can log in to create their own lists of books, along with annotations, comments, and ratings. Additionally, visitors can search and browse other readers' profiles, take literary quizzes, and look over hundreds of book lists. Author pages collect writers' bibliographies for an easy way to find more books based on those already read. Finally, the Recommendations area suggests more books individual users might enjoy, drawing from their ratings, tags, and virtual "shelves."
