I've been looking around in search of a unified catalog or discography of the broadcast transcriptions released on the World Program Service label of the World Broadcasting System. I found a very informative history as background information on another discography site (http://www.peggyleediscography.com/worldtran.html). From there, knowing that Decca acquired WPS "around 1943), I consulted Ruppli's Decca discography, but its coverage (in volume 3) of WPS seems to start in very late 1943.
Just to cast the widest possible net, I did consult Worldcat and even Google, so I'll be that much more chagrined if I've looked past something obvious, but I thought I'd see what light the collective wisdom here might be able to shed on what's out there.
Thanks in advance!
