This is one of those things that I wish I hadn't missed at CES. The Book Saver is a new scanning rig from Ion Audio. It has a novel design and a couple of rather interesting features. You'll need to watch the demo video to really grasp how this thing works. I'd seen some articles on this gadget, but only today did I find the demo video. It's not your traditional book scanner.
There's no word yet on price or availability.
