The other day I was talking with someone about "classic" books and I couldn't help feeling guilty at some books that I still haven't read. Yes, there will always be books considered "must reads" that I haven't yet got to, but that doesn't stop me from feeling bad about missing some. Here are some great books I haven't yet read. Some authors like Shirley Jackson, Thomas Mann and Agatha Christie I haven't read anything by. Should any become a really urgent reading priority because my life can't possibly be complete without having experienced it?

Do you have any "classics" you feel guilty to have missed?
