Hmmm... I've read 24 of them. There is at least 10 more that I've read part of. For example Lord of the Rings. I've tried to read that book a dozen times, but keep on falling asleep into the second book.

Keep in mind that we're not exactly a representative sample. A fair number of people on livejournal actually enjoy reading and writing. That being said a number of those books are a staple of school literature. Also, what kind of English speaking parent hasn't at least one of those to their children?
