I've noticed what seems a strange cataloguing method on a couple of Naxos CDs. To take two examples: (a) a symphony in D by Hofmann is identified as Badley D4, which I assume to mean that the cataloguer's name is Badley and the work in question is the fourth chronologically that Hofmann wrote in D. (b) similarly, Vanhal's Symphony in C (Comista) is identified as Bryan C11, suggesting similar conclusions. I may be missing something but this seems a rather clumsy way of giving a unique identifier to a particular work, especially as it appears that Bryan's work is restricted to the Vanhal symphonies because other works have either opus numbers or nothing. With BWVs, Ko"chel numbers and so on, you know where you are much more easily. I'd be interested to know why this particular method is used - perhaps because the cataloguing is a work in progress?
