So just as I was getting everything hooked up to the new Compact Jazz release group series, @drsaunde found this: https://www.discogs.com/Sarah-Vaughan-Sarah-Vaughan/release/12416881
It’s one of the releases in the series, reissued outside the series in 2003. So I entered all the edits to switch it back to a release series instead of release group. But then I got to thinking, do later releases outside the series invalidate the release group series? I’m sure it’s not super common, but it also seems like an awful headache for maintenance. ANY release group series could instantly become a release series just because someone decided to issue one of the releases LATER as a standalone. It seems to me that if the original release was part of the series, it should still be a release group series. What do you all think?
(There’s a secondary consideration in this case, which is that the Compact Jazz CD series was COMPACT Disc releases, which as you can see in Discogs existed alongside WALKMAN Jazz releases on cassette. I would argue that they’re effectively the same series, although there’s certainly a case to be made that they’re actually parallel release series.)
