[Blindmath] poorly prepared tactile graphics

[Susan Jolly]

The following is a wonderful resource on tactile graphics which was written
by a person who prepared tactile graphics for the Netherlands Library for
Audio Books and Braille from 1983-1989. I think this manual would be useful
for someone who prepares tactile graphics today and also something to use as
evidence if you are in the situation of trying to explain why the tactile
graphics you've received are unacceptable.
