This is indeed a huge collection and I am eager for even more of it to become searchable.
I already found a bunch of mentions, pictures, ads for records, and so on, in Broadcast, Sponsor, etc. of a 1940s-50s big band singer that I've been researching.

Subject: [ARSCLIST] American Radio History website
Doing some totally unrelated research, I stumbled across this huge
collection of scanned material related to radio's history.
Maybe you all know about this already, but I sure didn't.
Hope it is not too far off-topic for this list.
