I’m posting this on the talkpages for Category:Catalogues and Category:Classification systems. Looking at their contents, I’m not sure how they’re different from each other. I’m not (and won’t be) proposing a merger – I’m just curious. Maybe catalogues (among other things) use classification systems. That would make sense, but the current members of each category suggest the categories are wider than that. -- Northernhenge ( talk) 17:26, 12 May 2024 (UTC) reply
