This category lists those Greyhawk sources deemed canonical. In general, this category includes modules and sourcebooks published for the mass market and approved by the IP holder at the time of publication (ie, TSR or Wizards of the Coast), that are of significant value to the setting. This also includes materials that the IP holder releases via the web, as well as materials that were regarded as "generic" when first published, but retconned into Greyhawk by later authors. "Significant value," in this case, is broadly defined. A safe bet is that if the product is not written off as a whole by the IP holder, then it's probably canon. Note that this category may also include many general Dungeons & Dragons sources that may include only a minimal amount of Greyhawk material.
For further information on canonical sources, see the Greyhawk canon essay.
