The Guardian's 50 books you must read

Yesterday The Guardian published a list of 50 books you must read. There's no explanatory notes about the list (that I could find), but having looked at it I've come to the conclusion that all the titles have been made into films. Hence, if I was to view this as a list of films you must see my score would be relatively high. Alas, as a reading list, my score is typically woeful.

Here's the list in full (I've highlighted the ones I have read and put an asterix next to the films I've seen):

That makes it 19 out of 50 for me for the books, and 32 out of 50 for the films. How did you do?
