The Panopticon/Standardizing lists of appearances

There seems to be no cohesive style for the lists of appearances. For example, should the title heading be "Audio" or "Audio stories"? Short story formats are a major offender. Should it be "Title" or "Title (Anthology)" or "Title (in Anthology)" or something else entirely? There are loads of inconsistencies across the two-hundred-odd appearance lists. Basically, is there a style guide for appearances, and if not, can one be created?
