The following is a list of the documents needed in order to play Warhammer 40,000 8th Edition, published by by Games Workshop Group PLC.

This list does not contain rules sources that have been entirely superseded by others (such as the Primaris Captain and Primaris Librarian In-box datasheets), nor does it contain Beta Rules or Beta Codexes (such as the the Beta Adeptus Sororitas codex).

If I have missed any, or some are now outdated, please PM BaconCatBug with what I have missed and I will add them to the list.
