I went to the link and the search field was blank, so I typed in Tesla. The first book listed was the one (title same as in my original post). I didn't realize Barnes and Noble had so many listings of Tesla material. Of course B&N may, like Amazon, list most anything that has been published and depend on their listed source having it available when you order it. Amazon buys a lot of electrical books from the AVO Institute where I used to work. If AVO is out, Amazon may be out. I guess B&N would, to cut cost, not warehouse all the titles they list. My two local B&Ns were out of the books 2 days after I posted the sale.
