Online Edition of the 1972 Revision

The Nemeth Braille Code for Mathematics and Sciences, 1972 Revision (a.k.a. the "Green Book") is being encoded into MathSpeak, so that the book is accessible online. One of the goals of the MathSpeak™ project is to eventually encode the entire Nemeth book as an online reference for MathSpeak™.
