While the Gazetteer is an entirely new and independently-created set of spoilers, much is owed to those who trod similar paths in previous versions: this Gazetteer is therefore dedicated to Paul Waterman, author of the WCST Spoilers for NetHack 3.0; and Boudewijn Waijers, author of dungeon.map and quests.map for NetHack 3.1.3.
Useful criticisms and corrections were provided by: David Corbett, Michael Hedera, Kate Nepveu, Janis Papanagnou, Rast, runcible, Robert Schneck, Jason Short, Ste, Boudewijn Waijers, and Colin Watson.
