The following list comes from LibraryThing, DirtyLibrarian turned it into a challenge and my daughter posted her response. According to DirtyLibrarian:

"What we have here is the top 106 books most often marked as "unread" by LibraryThing’s users. As in, they sit on the shelf to make you look smart or well-rounded. Bold the ones you've read."

I have added a few additional flourishes. Asterisks indicate books that remain on my shelves though read, Italics indicate books I found distasteful or obtuse and did not finish.
