Peter & Mike, Thanks for the effort that you have put into obtaining the books that I asked about. I will get on the website that you have suggested Peter. If I can't get them through interlibrary loan then I suppose that i will have to buy them. I had tried to get one of the books through my local library and had high hopes of success when it showed up in their computer but received a phone call a few days later and was told that the price to borrow them would be exorbitant. I do appreciate your trying. Frank Kuhn ing. =20 Frank Kuhn
