The Dungeons & Dragons Rules Cyclopedia was published by TSR, Inc. in 1991, as a continuation of the basic edition of the Dungeons & Dragons fantasy role-playing game, which ran concurrently with Advanced Dungeons & Dragons. Its product designation was TSR 1071.
However, the book's introduction on page 5 states that it is "intended to be a reference volume for those who already play the D&D game ... this book is aimed at the experienced user ... [it] lacks many of the examples and patient explanation you'll find in the D&D box sets". The same year, a revised introductory Dungeons & Dragons set was released to introduce new players to the game.
This was the second revision to the D&D rules. These guidelines allow a player to develop and play characters from levels 1-36, and includes a special section on skills. The book also contained an overview of the Known World (Mystara) and Hollow World campaign settings. It also has rules on how to convert characters between the Dungeons & Dragons game and the Advanced Dungeons & Dragons second edition game.
The Rules Cyclopedia includes two optional classes to the game: the druid (introduced in the Companion ruleset) and the mystic (introduced in the Master ruleset, similar to the monk class found in Advanced Dungeons & Dragons).
Rick Swan reviewed the D&D Rules Cyclopedia for Dragon magazine #184 (August 1992). He calls the book a "stunningly comprehensive volume", explaining that it "includes more detail than most GMs will ever use [...] but if you want it, you can probably find it here". According to Swan, "Best of all, the material is a joy to read, thanks to the breezy style of Aaron Allston, who must've been genetically engineered to write RPG rules. This is a must for serious fans."
Shannon Appelcline said that the book "was a nice compilation that was appreciated by the fans".
