Book sales are up but long-term growth projections are pessimistic.
Some advice for the publishers: Lower your prices. High prices discourage impulse buying. I talk to a lot of readers who say that they regularly pass over books that they'd otherwise buy if only the price were three bucks less.
While I'm on the soapbox: The price of university textbooks is scandalous. Some textbooks run over a hundred dollars and the students are in no position to bargain.
