I've always thought that “perceptual disability” in this context is a rather strange term. I think “print disability” is better. Harkening back to the Marrakesh Treaty, it may help the cross-border sharing of what is produced, but still the issue is getting publishers to produce more to start with. That's where the act needs to do a better job in encouraging publishers to produce materials accessibly from the get-go.
