Hey all... LibraryThing member here. I keep meaning to sign up for goodreads to be able to compare but so far haven't.
But librarything also lets you tag books as read / toread. You can compare your library to others.. for example, how many books did you have in common with Ben Franklin or James Joyce?
Check out my library. (These are all my "have read" books). Well not everything I have read. Everything that was on my book shelf and many books I recall reading. I think of more all the time and keep adding them.
