I have some 78's from the 30's and 40's where there's not a designation of A-side and B-side. I 
think Victor started relatively early with catalog number -A and -B or -1 and -2 but I'm not sitting 
with the 78's to verify that. I notice that listings and discographies, in the case where a 78 isn't 
specified A and B sides, generally list the first take number as the "a" side, but even then there 
are exceptions because in some cases the earlier take number is not the known "hit" on the single.

As far as I can tell, there was no standard way to do this, including in the 45-RPM singles era.

Subject: [ARSCLIST] Record Sides

I'm posting this message on behalf of Eric Byron:
I have always wondered who decided, prior to 1930, which recordings would be
packaged together on records with two sides. Did the record companies have
formulas? Were the companies trying to promote side B by having it next to
side A?

Did the companies have an entire department, one person or both in charge of
such decisions?

Has anybody written anything on the subject?

Any help would be greatly appreciated.
