No, I have not updated this edition, however you can find the larger version that was developed for the 1999 NEC on the www.IAEI.org
web site publications list with the same title.
I can remember when I wrote this 1st edition, I used a Mac and typed it in ALL CAPS and was told that was not the way to write anything!
So not knowing how to do the change for sentence case I started all over again, it took me eleven hours. Later I had someone who knew how to set up the word file, prepare it for me then it was published. I will develop audio files for each chapter soon. Any suggestions will be appreciated.
