A lady came up wanting the book A Kindness to Birds by Preston Brooks. I looked everywhere; in our catalog, in our consortium catalog, even on Amazon...nothing.
Turns out it's actually a made-up book from the novel How I Became a Famous Novelist by Steve Hely! I'm not sure how she heard of it, since she said she hadn't read the Hely book. She walked away before I could ask!
[I have read it and it's hilarious but kind of ruins "literary" fiction for you for a while.]
