Google - and libraries - use copiers designed to allow you to photograph a book page without mangling or destroying the book, and with the ability to flatten a page so that the resulting copy is clean. These copiers aren't hugely expensive. If someone can build one on their own, as referred to in an earlier post, that's probably the best solution.

The journal publishers have already discovered this approach, by bundling all their titles in one enormous package that they license to large libraries. Problem is that libraries are now paying more than they can afford for more information than they (or their users) need. And the publishers won't back down, so when the contract is up, libraries find themselves in the position of all or nothing - and all is usually considerably more expensive than it was the first time around.
