Here’s a book I should be reading: Hans Rott, Change, choice and inference: A study of belief revision and nonmonotonic reasoning. It will be directly thesis-relevant, and judging by a couple of papers by the guy I’ve read it might be something I’d like to own myself.

Except for one leetle teeny detail: it costs $130.

It’s a 300 page hardback, available from the publishers for $130, Amazon.com for $274 (!!), Amazon.de for €95, Amazon.co.uk for £83…

Thankfully the university library has a copy. It’s really a shame though, because there’s no chance I’ll buy it, no matter how relevant it might be. This is a self-reinforcing publishing model: high prices mean nobody except libraries can buy the books, which forces small print runs and thus high prices. Sad.
