I use Goodreads to keep track of and rate the books I've read. You can view them here, organized by year read or by my rating of the book. Though it depends on the genre, I usually rate books based on how much I enjoy them, the quality of writing, and how much they change my perspective. If you're looking for the books I'd recommend to most people, head straight for the ones I've rated 5 stars.
