The book-scanner was built because I wanted scanning books to be
affordable -- to make it possible to email a printed book almost as
easily as a digital one.
This facilitates the propagation of the best
material. Without the ability to scan books, one is likely to send
an inferior text merely because it is already available digitally.
Luckily, most books are already available through internet
book-sharing networks (if you don't know how to find them, ask me about
it), but it is always frustrating to be missing a text you need.
In order for digital books to be maximally useful, they need to be
available for modification and incorporation into other texts -- that
is, they must be copy-and-paste-able. This requires an OCR-able image. Besides
low-cost, this is the primary goal of my scanner design.
