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.
