Powell’s: Book Lovers’ Ground Zero

I was doing a word search in the Associated Press photo wire this afternoon when I chanced upon this photo, which brought a smile on a snowy March 1 day. I have spent several afternoons sitting in the coffee shop of Powell’s book store in Portland, approximately where the woman in the photo is sitting. And you probably have, too.

Question: Which book did you last buy at Powell’s?
