As it turns out, I have not actually read everything. In a moment of idle curiosity, I pulled up the Modern Library's list of the100 Best Novels, and discovered that I have only read 22 of them.
I don't know if it makes it better or worse to mention that in addition to those 22, I started 16 of them, but for a variety of reasons (some very good*) didn't finish. Some of these titles I intend to read in the future, but others fall under the umbrella of "I didn't read it in college, and I'm certainly not going to read it now." Henry James, Joseph Conrad, and James Joyce, I'm looking at you.**
* I was 50 pages from the end of Lolita when some jerk came up to me in the high school library and told me how it ended. I've never had the heart to pick it up since.
** Lest you think I majored in English at some half-baked school that did not require its students to read these venerable gents, I have read at least two books by each James, Conrad, and Joyce, and am somewhat at odds as to determining which of them I hate most although I suspect it's Henry James.
