David Gleason is a fine caliber of radioman.
These days we call it the Broadcasting & Cable yearbook. David Gleason is scanning every page of all the Broadcasting Yearbooks from the late 1930s to 1980. The sheer volume of material is amazing. But it's not just that. He's scanned hundreds of copies of Broadcasting Magazine, Radio Annual, Communications Magazine, Whites Radiolog, radio Index, Jones Log, Stevenson's Bulletin... the list goes on. He is a man on a quest. His collection is amazing, and growing.
