Comments:
a) Way too much Dickens and Austen here. 10 of 100 from just those 2? Ridiculous.
b) There should have been some "something by" - I've read Hunchback, not Les Mis. That should count for something. Also, I've read a lot of Dostoevsky, but only C&P is on the list (even though The Brothers Karamazov is, IMHO, the greatest novel ever written). Lord, I've tried reading Tolstoy several times. Can't get through more than 10 pages. As Emo Phillips said: "There's nothing like curling up in front of a fire with a copy of Tolstoy's War and Peace. Y'know, a thick book like that can feed a fire for hours". Especially prodigious authors, like Shakespeare, should get categories - have you read at least one Shakespearean comedy? Tragedy? History? It the Chocolate Factory really that much more edifying than the Great Glass Elevator?
c) No Mark Twain? A shonda. I can live with no Arthur Miller.
d) Alex Haley should be on the list, if for no other reason than the cultural importance of his books. Either Roots or The Autobiography of Malcolm X should be on the list. The FOuntainhead should be on the list for the same reason.
e) I'm probably defining "the Bible" differently than the compilers of the list.
f) I do not count it if I only saw the movie.
g) I do count it even if I only read it as part of my formal schooling and didn't like it.
h) My wife has read 49 of these titles. That's impressive.
