This is a great idea, much of it can be done with third-party Drupal modules such as Location and a little bit of elbow grease (yes, programming skills). That would allow you to at least assign a location to a book, but it would require more consideration about the book's movement. Lee LeFever, with his site The World Is Not Flat, does something like this, but instead of a book, he tracks where he's posting from. What Lee has did require programming, however, but there is work being done to make something like that into an official module.
