LibraryThing is a great way to keep track of what you're reading as well as find out what others have enjoyed. LibraryThing helps you catalog your books, get connected to to others who share similar tastes and receive suggestions and book reviews for future reading pleasure. Especially of interest are "I See Dead Peoples Books" which are legacy libraries of famous dead people and the "Zeitgiest" page which lists top reviewed books, most popular authors, largest libraries, most translated texts and more. Sign up for library thing to catalog your reading interests or explore those of others. It's really fun!
