The Lost Handbook

A fan-compiled reference for the AD&D game, gathering articles from early TSR publications including Strategic Review and Dragon Magazine. Written by contributors such as Gary Gygax, Robert Kuntz, Roger Moore, Frank Mentzer, and Len Lakofka, it collects official rules updates, commentary, and expansions in a volume comparable in length to the Player’s Handbook and Dungeon Master’s Guide. The material covers rules and guidance that appeared in the magazines or was identified as official, serving as a historical supplement to the early AD&D system.
