Recently I had to go through my collection and add another reference attribution to my envelopes and online gallery - Monnaies de l'Empire Romain III - J.-B. Giard. I picked up this great catalogue a couple of weeks ago and have had quite a bit of fun using it, however, I hit a snag. What abbreviation do I use - BNF, BnF, BN, BNC, or Paris? There seems to be no standard acronym for it in trade. Indeed, dealers, and auction houses are all over the place regarding many of the above variants, with collectors preferring BnF. At first I used the BNF abbreviation (a slight variant of BnF), but this didn't sit right with me. 'BnF' is a common abbreviation for the Museum itself, not the catalogue. Also, that acronym wasn't in keeping with how the other major references are abbreviated (RIC, BMC, RSC, etc.). I sought help from the new RIC II.1 abbreviations page where I found 'BNC' is preferred for the work. As a matter of fact, when I looked in the introduction to Monnaies de l'Empire Romain III itself, BNC is their official abbreviation. Plus, a whole heap of academic works employ that abbreviation for the catalogue. So, 'BNC' it is. It's odd how something so minor can take you down a rabbit hole, which is all part of the fun I suppose. To a generalist this concern over the proper reference citation would seem a bit obsessive. To a specialist it's vital - other specialists need to know what catalogue you are referencing. Anyone else enjoy playing with the 'alphabet soup'?
