Although the matrix series for Columbia's transcriptions were not included in the Columbia discography, Tim Brooks told me that many of these series are documented at Columbia. Victor used one numerical series for all of their recordings although there are blocks that were set aside for different studios and sometimes run parallel. But although the paperwork for most of their client recordings are not in their files, the dating info can usually be closely extrapolated or specifically interpolated. The "Movie Book" with listings of their recordings for film soundtracks for 1928 to 1932 is now once again available, and this can also help find things. The AFRS and V-Disc recordings that are Victor based can also be determined thru the common matrix series. While there is a very good discography for V-Discs by my friend, the late Dick Sears, the AFRS discography is really more a program series listing. Because of the generally crappy ways OTR people fail to properly identify the discs they had made their dubs of, most of the information that could have been compiled over the past four or five decades has been lost. A record collector would never fail to include discographical info with their dubs but OTR collectors seem to be angrily defiant against copying down the info off of the discs they have. Some of them seem to prefer not having proper identification of the programs. (There also are some OTR collectors who don't want the recordings to sound good -- one guy wants the programs to sound like the old Philco with a torn speaker cone he had in his bedroom as a kid.) So what are the numbers of the discs you need identifying? Mike Biel [log in to unmask] From: Randy Riddle <[log in to unmask]> > I recently obtained a "mystery disc" pressed by Columbia - laminated shellac, just over 16", with a "Sound on Disc Division" label common to discs Columbia manufactured in the early 30s. I've also run into a couple of Victor transcriptions from the early 30s with blank labels that have been difficult to get some concrete info about. > I've been curious if the ledgers for the transcription divisions of Columbia and Victor or other labels have survived. Has anyone done any discographical research in this area? I've seen some discographies of Armed Forces radio transcriptions or Music Library releases. The ledgers from Columbia and Victor and some other companies, like Allied, would probably be of great interest to researchers on film or radio history. Randy
