I think the worklist/composition list pages are in use of a style guide- not to enforce uniformity of format, but to remind people of their audience , goals, etc. Too often the entries in these worklists resemble gnomic marginal jottings full of abbreviations that need expanding out, for example. They're taken from Hofmeisters Monatsberichte often enough, I know, which was full of such abbreviations; but I think that was an industry publication, aimed toward people who knew what the various terms and abbreviations in German meant already. I don't think it's quite as safe to assume that everyone coming on your worklist, especially an English language reader, knows that "Kl" is piano, not Clarinet or perhaps older-style Klavichord or... but that's too specific (if still general) an example and there are too many (of which my painfully bad attempts at contributions to composition-etc. lists provide quite a few.)
I don't want this to go overboard personally and would argue for guidelines over rules for the most part (except where obvious - sticking with the existing rules of the site, of course) , but the unreadability gets a bit much.
