"One scheme that might cut the cost of textbooks would be to release all in a binder format, where future updates would consist of small kits to replace superseded pages and every effort would be taken not to upset pagination."
my marketing professor did just that, and priced it @ $20. that barely covered the cost of printing. it's been 15 years, and i still respect him for doing that.
your FReephandle is really funny! one of my dogs loves to have his chest scratched, and the other, her butt. so, when i scratch her butt, i say, “scratchy the butt, scratchy the butt.”
