David, thank you.
Last week I was in Kansas City, Missouri, and spent some time at the Linda Hall Library. It is a privately endowed science and engineering library which is open to the public, with an emphasis on preserving periodicals. Their collections are quite superb. I know of nowhere else like it. It is also a beautiful building with nice lighting too. Their web site is

Any way I have copies of the text of both versions of the infamous Sosin article on H.F. receiver reception failure. I intend to compare them word for word.... I think that I know of at least 3 libraries which have the original publication. The Marconi Company was clearly doing some very wishful thinking if they began to think that all the copies would come back.
