ok, thanks. Now I did the change for Resonance, Musikfest, Privilege and Favorit, which is that I’ve created a new series (except Resonance which was already there). I’ve added a “don’t use” warning to the disambiguation of the label versions, and some instruction to their annotations.
These 4 cases are very similar, all are reissue series (btw: Why does Deutsche Grammophon need 4 of them?)
The two remaining cases Deutsche Grammophon Junior and Deutsche Grammophon Literatur feel a bit different to me. I stopped and reverted the change for “Literatur” when I was half way through and realized that this appears to be more independent than the first 4.
Label experts: What about Deutsche Grammophon Junior and Deutsche Grammophon Literatur? Are they proper labels on their own, or should they be converted to series, too?
