If someone would set up a library, there are lots of exemptions in copyright law for those. It would probably have to be set up as a non-profit corporation; otherwise it might be possible for a copyright holder that wants to stir up trouble to claim that it's not a "real" library. Copyright law allows a library to make a (single) photocopy of a document

lend out in place of a rare document. I think a case could be made that a scanned image is equivalent. You'd just have to require that the borrower return the scanned image when they're done with it. Perhaps a scheme like netlibrary uses would work.
