As mentioned in other places on my website, one of the most influential books I have ever read is :-

The Body Electric --written by Dr Robert O Becker and Gary Selden, published by Quill (William Morrow and Company Inc), ISBN No 0-688-06971-1. 

Dr Becker (or, rather Professor Becker, as he is now Professor at the State University of New York, Upstate Medical Center, and Louisiana State University Medical Center in Shreveport) has twice been nominated for the Nobel Prize. He has recently published a sequel to the above book, called Cross Currents, where he not only updates us on electromagnetic medicine, but also warns us of the growing dangers of electromagnetic pollution. Its ISBN Number is 0-87477-609-0.
