What about books in a series? e.g., "GURPS Power-Ups 1: Imbuements" or "GURPS Dungeon Fantasy 3: The Next Level"? I'd like to just say "imbuements" for the first one, or maybe "power-ups" (or "pu") and "imbuements" as separate tags.

Also, could you include a list of common abbreviations in the first post here, so that newcomers can determine what things like "df", "ss", and "pu" stand for?
