Where are their scanning centers? The link (http://www.archive.org/scanning) said they have lots of them, but doesn't describe where. I assume I can't just show up and expect to get my books scanned, so I'd be interested to understand the process better. Can an individual participate or are they only working with their partners?
I agree. The janko keyboard layout for the piano appeals to me because no key is different from another. For instance if you learn one major scale on the janko keyboard you now know them all. Doing something similar for music notation is hard, but would be incredibly useful if done well. See http://musicnotation.org/ for some attempts.
