Kindle earns D for textbook use

[Bedouin]

<p>

What kind of circular logic is that? Older versions remain attractive BECAUSE the new ones are simply too expensive. New versions are expensive because it is nothing short of a racket where authors and publishers are in deep cahoots. Professors routinely push new versions because of their OWN interest.

<p>The logic is perfect though. By publishing new editions and getting professors to require them, you can make a seemingly identical older version obsolete. Just make a few minor modifications (move some pages or chapters around, change a few numbers in math textbooks to make sure that the older textbook is impossible to use if the professor assigns practice problems out of it) and you can make money back.</p>
