I've read only 16 on that list...but on average I read at least 10 books a month. When I was in school I generally read 10 books a week, as that was how many I could check out at one time!
I'm currently re-reading the Hitchhiker's Guide to the Galaxy trilogy (that has 6 books in it? LOL). Maybe I'll print out the list & start working on the rest of these "classics"....
