UPEI has digital library system called Islandora[1] that does this sort of thing. I worked for them for about 6 months. It's a set of Drupal modules that interact with the Fedora[2] Repository (not the OS). They're pretty successful, with hundreds of installations all over the world. They have been scanning hundreds, if not thousands of books, newspapers, and maps so that they can be stored digital and accessed freely.
One example I think is pretty interesting is Island Newspapers [3] where they have scanned every issue of a newspaper in PEI, Canada called the Guardian going back to 1890.
