Re: scanning bound volumes
Minolta makes a face-up bound volume scanner, the Epic 3000, that not only accommodates the binding, but also has an algorithm that straightens the line curvature caused by tight bindings. The book has to be opened pretty flat, however.
Xerox used to make a face-down scanner that may still be sold as the BookWise or The Reading Edge. It requires, I think, a 120 degree opening. Zeutschel makes book cradles for microfilming and scanning. One of their microfilming approaches only requires opening a book 60 degrees. Other book cradles intended to be used with a digital camera on a copy stand seem to be less-forgiving; not only do you need to fully open the book, but they expect you to put a glass down on it to flatten it (to avoid the curvature problem).
There are some photocopiers (typically using the face-down approach) that only require opening the book around 120 degrees. You could photocopy, then scan the copies with a high-speed sheetfed scanner. Or microfilm and scan the film.
