Television Factbook (later Television & Cable Factbook) has been published since 1945. (http://www.warren-news.com/factbook.htm) Radio is your main thing, but television is closely related to radio - broadcasting includes both radio and television.
FM Atlas has been published by Bruce Elving since 1972.
Please consider adding editions of these two book series to your website.
I've considered FM Atlas, but Bruce Elving has corresponded with me and appears totally opposed to having his publications posted, as it "would destroy the value of issues for collectors."
To me, that is an unfortunate and narrow view, as his publications are a marvelous and fascinating way to track several decades of the development of FM and I would gladly buy more server space to make them available as a reference.
I don't know where to get the TV editions; I was really hoping that my costs on this project would end at this point (I'm over $30 k now) and unless I get donations, I don't think I will try to fully cover TV also.
Television Factbook is a different publication from Telecasting Yearbook, plus it's from a different publisher. Have you heard of it before?
I know the book is from a different publisher; I have never owned one nor seen one "up close" either, although I have seen references to it in the past.
You live in the Los Angeles area, don't you? You should go to the UCLA's Young Research Library, look for call number HE8698-T236, and take a look for yourself when you have the time.
