The main explanation given to justify $300 price tags for textbooks is the short "exploitation window" for each title. Because of used book sales, new book sales are eroded, so publishers are forced to jack up prices. Hm... I like how publishers end up the victims in that story.

Also interesting is the part of the interview with an executive from a big publishing company who seems convinced digital textbooks are the future. Sure. Maybe. I wonder if they asked teachers what material/tools they need for better teaching, or if they came up with the strategy on their own. I'm not so sure "digital editions" will be very good. If they use DRM, then the reader experience will be crap, and if they don't then piracy will hit them much harder.
