System Reference Document

The System Reference Document, or SRD, is the collection of open gaming works licensed under the Open Gaming License by Wizards of the Coast (or WotC) and based upon their Dungeons and Dragons role-playing game. The SRD forms the basis of WotC's various d20 System role-playing games, including the d20 System itself, d20 Modern and d20 Future.

The SRD is freely available from the WotC website as a series of Rich Text Format documents that specify the rules, races, classes, feats, skills, various systems, spells, magic items and monsters compatible with the d20 System version of Dungeons & Dragons and various other roleplaying games from Wizards of the Coast. It is continually updated to comply with errata issued by WotC. Compared to the published source books for the Dungeons and Dragons game, the SRD provides the same basic rules but lacks "flavor" elements. There are no named gods, none of the spells have significant NPC names, there's no mention of Greyhawk or other copyrighted works by WotC. There are also no rules for character creation, for advancing characters in level, calculating experience, or anything else related to the topics forbidden by the d20 System License .
