Goodreads is a wonderful resource to track your reading and to see what other people are recommending. Lists are generated by users, so it's a great opportunity to find what like minded people read.
This resource is an excellent means of finding your next favorite author. Enter an author's name and the Literature Map will create a visual web of similar authors. The closer an author's name is to the center of the web, the more similar they are to the author for whom you searched.
