So, what are the 10 most important books you've never gotten around to reading? In addition to many of the ones acknowledged in this post and the post it links to, I'd have to admit to at least:
"The Rise and Fall of the Third Reich." I always get to the point where we learn that Hitler was a failed Austrian painter named Schickelgruber, put the book down and decide to pick up again in a day or two. I don't, then pick it up in a year or two to start all over again.
"Moby Dick." Honest, I've tried and tried and tried. But's it's as boring to me now as the first time I ever picked it up. Gregory Peck was OK, but I didn't even like the movie.
"The Wealth of Nations." I've read lots of excerpts, followed the debates of people arguing back and forth about it, but I've never actually read THE book. I don't feel too bad. I suspect this is the most quoted book actually read by the fewest people.
"On Walden Pond" or whatever the name of the book actually is. See "Moby Dick" entry.
