The Dungeons and Dragons Collection collects material related to Dungeons & Dragons and other games from 1974 to 1981. This collection is made up of five series: RULEBOOKS, PERIODICALS, SECONDARY ADVENTURE MATERIALS, OTHER GAMES, and MISCELLANEOUS RULEBOOKS contains official Dungeons & Dragons rulebooks released by TSR PERIODICALS contains licensed fan magazines produced by Judges Guild that discuss Dungeons & Dragons and publish fan-made material SECONDARY ADVENTURE MATERIALS contains both official adventure modules released by TSR and licensed Judges Guild modules and tools. Most of these materials were designed specifically to work alongside the official Dungeons & Dragons rules, while others are not designed for a specific game system, but are still compatible. While many of these items are numbered, they are not necessarily part of a connected series. OTHER GAMES contains board games and game supplements for non-Dungeons & Dragons games. These materials are unrelated to Dungeons & Dragons, but were created during the same time and can be considered contemporaries. MISCELLANEOUS contains miscellaneous materials
