You have that thing it can be added as a separate entry if considerable time passes which I know it's been used throughout the database. Here it's 30 or 10 years after the first release/last entered reprint so that criteria is good.
I don't remember reading the timeframe has ever been clearly defined though so you also approved
this digital version for instance which came out only around year and a half after the CD. This supplementary time criteria for digital "reprints", any envisioned minimal value or just keep accepting on a case-by-case basis?
