CompendiumSo you would rework all catalogues in this mindset, like Dy F# and Dy R for France? Or even KM# ? Or just for new catalogues ?
At least for new catalogues, it makes sense to me to have complete citations, including volumes. I am not sure about the previous catalogues and the logic followed when they were added. I see examples with volume codes both for catalogues that continue numbering or not.
One existing catalogue where I would say it makes sense to split the codes is BMC Greek:
https://en.numista.com/catalogue/catalogue.php?id=737
https://en.numista.com/catalogue/catalogue.php?id=169
As you can see, only volume 1 has a separate code, and I am not sure why. I am happy to help reassign the codes if you go one by one with new volume codes.
This one is to me particularly problematic as I am double-checking the references for the provincial coins already assigned. For some cities, it's difficult to know which volume to check. Especially for the denser areas in Anatolia, Greece, and Syria, or even for Moesia/Thrace. Some cities changed to new provinces as they became Roman and the borders changed, so they may appear for example in Mysia, Lydia, or Caria in different references. For example, Cidrama was originally in Phrygia and later in Caria. So which BMC volume to check? Assuming one even knows the region the city belongs to, which is often hard to find, or even unknown.
To me it makes sense that this time-consuming research work is only done once, when the reference is added. Rather than each user having to go through the same process again every time they need to check the catalogue.
