Updated.
These are the top 106 books most often marked as "unread" by LibraryThing's users (as of today).
Bold what you have read, italicize those you started but couldn't finish, and strike through what you couldn't stand. Add an asterisk* to those you've read more than once. Underline those on your to-read list.
I will read any that I haven't read so I'm not going to underline all those!
