HOWTO make a $300 high-speed book scanner

Daniel Reetz posted an Instructable about making your high-speed book scanner from trash and cheap cameras. His version is only around $300. I don't think I'd make one myself, but I'd love for some generous maker to install one at my local public library! From Instructables:

After suffering through scanning many of my old, rare, and government issue books, I decided to create a book scanner that anybody could make, for around $300. And that's what this instructable is all about. A greener future with more books rather than fewer books. More access to information, rather than less access to information. And maybe, years from now, a reformed publishing/distribution model (but I'm not holding my breath...).

I've built two of these things now, and this instructable covers the best parts of both of them. You can build a book scanner using only hand tools plus a drill. I realized that not everyone is comfortable with using all the different hand tools you might need to make it. So I scanned a book on using hand tools that should answer all your questions. ;)
