Other Efforts
We are not the only people doing book digitization. Others efforts include:
DIY Book Scanner
The DIY Book Scanner project is doing very similar work with very similar parts. If you're looking for alternate designs along the same lines, they're the first place to look.
Internet Archive
The Internet Archive has a some large Scribe machines and some free software to go with it. The machines are described in this article.
On the blog, John Gilmore nudged us to ask the Internet Archive to release updated software, and James Vasile did so via email. In the mean time, we'll start looking at the old stuff on Sourceforge.
CopyBooks
Another Brooklyn-based book scanner developer has a laser cut scanner available with some custom software for page splitting and de-warping.
Long Now Foundation
The Long Now Foundation is developing a software tool to easily convert documents between digital formats.
