"The Inventions, Researches, and Writings of Nikola Tesla" is on sale at Barnes and Nobles Booksellers for $7.95. The saleslady here in Dallas said it will be the same price at any B&N in the country. I bought it over a year ago at close to full price ($25). It is a prretty technical book. There are 43 chapters in 493 pages of Tesla's papers on AC currents, motors, condensers, dynamos and transformers. I've only read a few chapters. Seems like my career is requiring me to do so much reading that my reading for pleasure or electrical curiosity is taking a back seat.
