Herb over at Places to Go, People to Be wrote a post about something I'd actually been meaning to mention for some time: the bibliography at the end of RuneQuest, which is entitled "Appendix N," just like the one in the AD&D Dungeon Masters Guide. So far as I know, RQ is the only game besides AD&D to literally have an Appendix N, but, as I've noted before, bibliographies are a fixture of many an old school game. Indeed, I'd go so far as to say that, if a RPG includes an extensive bibliography (rather than mere ludography or "filmography"), you're probably looking at an old school game, or at least one with old school inspirations.
What's interesting about the RQ Appendix N is where it overlaps with Gygax's list and where it doesn't. You can find Howard, Leiber, Moorcock, and Tolkien among the authors it shares with AD&D, but also Smith, who somehow never made the cut in the DMG. The majority of the remaining books in the appendix are historical books, mostly about the ancient world and military matters, which only makes sense given Glorantha's overall feel and the origins of its game system in the Perrin Conventions for OD&D. Interestingly, RQ's version is an annotated bibliography, so you can read why the books were included.
Anyhow, I'm going to make a point of trying to include an Appendix N in any RPG project I write from now on. It's a great homage to not one but two classics of old school gaming and anything that might encourage gamers to read books other than more game books is a good thing.
