The 'print on demand' model of bookselling is just in it's infancy. I predict in the not to distant future that all hardcopy books will be delivered thus. Shop on-line, and if you want a copy of what you see press the 'buy' button. It gets spit out to a printer, and delivered the next day. No more brick and mortar stores and that's only bad if you own stores. I don't.
