I would support this concept, if they did away with a few of the revisionist textbooks in trade.
In fact, if you have a computer, why do you need any textbooks? All the information you need could be supplied via software or CD.
In the long run, it would be infinitely cheaper to provide every HS student with a laptop and books on CD than provide them with umpteen 10 pound textbooks. Textbooks are outrageously expensive.
I actually think that textbooks are going the way of the dinosaur. Even in college, why do you need a textbook if you have a computer?
Textbooks are outrageously expensive because publishers have a captive audience and can essentially charge whatever they want. If the physical books are replaced with electronic text, count on the software license costing as much as the original book.
