Looking at this page, I'm struck by the thought that there are hundreds (if not thousands) of scholarly catalogue systems, and that it is extremely impractical if not virtually impossible to list them all on one page. What I think may be more useful is to put a short description of each system on the category page for the composer to which it applies (or in the case of several conflicting systems, a separate subpage could be created). This has already been done in a few cases by Davydov, and makes a lot of sense - the information is right where people would logically think to look for it, on a page about the composer. This would also solve the problem of the same letter being used for multiple composers, because the information put on each page would only pertain to that exact system. Opinions?
