There simply wasn't room in the booklet for this. I had a word-count to adhere to and tried when I could to mention little tidbits about what survives and what doesn't.
In a nutshell, I can tell you that Edie has masters of the surviving shows in a variety of formats in an archival storage facility in CA, which I visited a few years ago when I began research on the project. Some material -- scripts, and audio transcription discs of live shows from 1953-55 (no kines survive) -- are on deposit at UCLA. Some kines were transferred expressly for this project, some transfers that were used were made in the early 90s and some were done 5-10 years ago.
What I'm hoping people will turn up in closets, attics, trunks at Michigan flea markets, etc are kinescopes of Ernie's daily morning shows and weekly evening show for CBS (1953-55) and of the Dumont show (1954-55), as those are the years with the biggest gap in extant 16mm.
