Back in the primordial days of tabletop roleplaying – when dice were chiseled from stone and character sheets were more suggestion than standard – Dungeon Masters had to brave a realm far more terrifying than any beholder’s lair: the rulebooks.
Let’s rewind to 1977. Dave Arneson (yes, that Dave Arneson – co-creator of D&D) looked around at the growing chaos of supplements, expansions, gods, monsters, spells, and charts, and said, “You know what this needs? A damn index.”
Enter The Dungeonmaster’s Index – a humble, unassuming little booklet that might just be the first-ever DM utility tool. No stat blocks, no flavor text – just an alphabetized, page-number-slinging, cross-referencing machine of order in a world built on chaos.
The Dungeonmaster’s Index is exactly what it says on the tin: an index of monsters, spells, magic items, and reference tables from early D&D material – including Greyhawk, Blackmoor, Eldritch Wizardry, Gods, Demi-Gods & Heroes, Chainmail, and more. It’s like the Google of 1st Edition D&D – if Google was printed on 70s-era cardstock and didn’t mind mixing demons with dolphins.
This was pre-Monster Manual, pre-Wiki, pre-“ask your phone.” If you needed to find what spells druids got at level 6, or which book had stats for bugbears, you either flipped like a madman or you bought Arneson’s Index and turned to the right page like a boss.
And for the hardcore collectors or OSR (Old School Revival) junkies today, it’s a gold mine of early D&D cross-references – your roadmap to the weird and wild days before the rules were codified (or even coherent).
Balrogs are in here – before the Tolkien estate kicked in the door.
Robots and Androids – yes, even in 1977, Arneson was saying “sci-fi belongs in your fantasy.”
Sea Monsters, Mermen, and Masher Fish – the aquatic bestiary is oddly rich.
Demogorgon and Orcus – the OG demon lords show up with full reference trails.
And of course, the final pages are just… tables. Tables on tables. Tables about weapons, monsters, experience points – if Gygax thought it deserved a chart, Arneson indexed it.
If you’re running a 1st Edition campaign, or something retro-clone-y like OSRIC or Labyrinth Lord, this little book is a legend. But even for 5E diehards or Pathfinder fans, it’s a fascinating time capsule – proof that even in 1977, the DM’s greatest weapon wasn’t the rulebook… it was knowing where to find stuff in the rulebook.
So if you stumble across a beat-up copy of the Dungeonmaster’s Index at a garage sale, don’t scoff at the old-school layout or the black-and-white art. You’re holding a piece of D&D history – and a love letter to the most underappreciated skill in tabletop gaming:
Being ridiculously, obsessively organized.
