OpticBook 3600 is a highly recommended book scanner that works like a normal
flatbed but incorporates a clever piece of technology called Shadow
Elimination.
This means you can scan any book, up to A4, completely flat on the scanning
glass with no annoying spine shadow or distorted lines of text. It connects
via USB 2.0, has an optical resolution of 1200 dpi and is the first truly
affordable book scanner for schools we ever seen.
The software included even properly rotates and saves your pages in the
correct order. The result is a perfectly scanned image with no annoying book spine shadow and no distorted lines of text.
