From bookshelf to dungeon - Appendix N and the pulp roots of D&D

Lake Geneva, Wisconsin, 1979. Gary Gygax is finishing the Dungeon Masters Guide, the thickest and strangest book the young hobby has produced: tables for gravity, for diseases, for the odds of a hireling deserting. And at the very back, after hundreds of pages of rules, he places something that is not a rule at all. A reading list. "Appendix N: Inspirational and Educational Reading", one page, twenty-eight authors.

It reads like a wishlist for a secondhand bookshop. Poul Anderson. Leigh Brackett. Robert E. Howard. Fritz Leiber. Michael Moorcock. Jack Vance. Gygax himself called them the source of many of the game's concepts, spells and monsters. Hold the list next to the rules and you see that was not modesty. Dungeons & Dragons is not a world conjured from nothing. It is a bookshelf that was handed dice.

The library behind the game

Take the magic. In D&D a wizard memorises spells in the morning and loses them the moment they are cast, as if the words evaporate from his head. That system is called Vancian magic to this day, after Jack Vance, whose Dying Earth stories work exactly that way: spells as living things that barely fit inside a human mind. Vance did not object; D&D was even allowed to use his Ioun Stones, on the condition that his books got a proper mention.

The alignment axis of law and chaos comes from Michael Moorcock's Elric stories and Poul Anderson's Three Hearts and Three Lions, the same book that supplied the paladin and the troll that will not stop regenerating. The barbarian is Robert E. Howard's Conan with a new serial number. And the thief, guild and all, steps straight out of the alleys of Fritz Leiber's Lankhmar, where Fafhrd and the Gray Mouser fled across the rooftops mid-argument; it is no accident that Leiber coined the term sword and sorcery. Read these books and the game suddenly points at everything.

The author who was barely there

One name made the list but always came with a footnote from Gygax: J.R.R. Tolkien. His influence was minimal, Gygax insisted, and frankly he found the trilogy rather slow. The game itself told a different story, with its halflings, rangers and orcs, and so did the lawyers of the Tolkien estate: under legal pressure the hobbit became a halfling, the ent a treant, the balrog a balor. How Middle-earth and the table kept finding each other afterwards is a chapter of its own. But the contrast says something: Gygax defended his bookshelf, not the bestseller. His game smelled of pulp, of cheap paper and quick knives, not of mythology.

A list with frayed edges

Honesty compels: Appendix N is not a canon, it is one man's bookcase, frozen in 1979. The list leans heavily on American pulp from the thirties through the seventies, and the women on it, Leigh Brackett, Andre Norton, Margaret St. Clair, were skipped for decades by readers who had no trouble remembering Conan. There is also fair doubt about whether the game grew from the list quite as neatly as the list suggests; with Gygax, memory and marketing sometimes blurred. And some of the books have simply aged badly. Work through the list today and you find treasures as well as things better left on the shelf, and that deserves saying.

The list that came back

Because that is the strange part: the reading list outlived the book. When the Old School Renaissance looked back, early this century, at where the hobby came from, Appendix N became the password. Publisher Joseph Goodman read the entire list and built a game around it: Dungeon Crawl Classics, which does not want to be D&D but the books D&D came from, down to a boxed set that lets you play Vance's dying earth yourself. Even the fifth edition of D&D carried a reading list again, duly updated, as Appendix E.

Forty-seven years after that single page at the back, the list still does what it did on day one: it sends players to the library. One concrete detail, a spell that evaporates, a troll that refuses to die, and you suddenly understand where half a game system comes from. The dungeon began on the bookshelf. It is still there.
