From a used copy of No Exit that I bought a week ago:
"I hope someone can still find a way to read and enjoy these books. The annotations written inside were based on the number necessary to get a grade rather than providing thoughtful commentary. While many of the books I annotated are among the best works of literature known to man, I will not be able to read them again using these copies because I associate them with a class I absolutely hated for a teacher who didn't teach. Best of luck and thank you for giving them a new and better life."
The book cost $7.80, but I got it more-or-less for free in trade.
