About a year and a half ago my reading group read a book related to my primary scholarly subfield. It was long, and parts of it I didn't have time to read carefully, but what I did read blew me away. I knew I'd be going back to it, and I wanted my own copy. . . but the damn thing was more than $150.
A couple of months later I heard an excellent paper on a similar topic, and when I learned that it was derived from the presenter's newly-published book, I made a note to look for it. Once again, the price deterred me: $95.
Well! Patience is sometimes rewarded: last night I got an email from a journal asking if I'd be interested in reviewing both books. If so, they'd ship my copies right away.
It's a racket, I know--and the bigger issue is that a certain Cambridge University Press doesn't price its books so that faculty and grad students can actually afford them--but 24 hours later I'm still dancing around my apartment, emitting occasional squeals of joy.
