The term '''"accepted sources"''' as used in the ''Lexicanum'' describes the body of source material that an [[Warhammer 40k - Lexicanum:Editors|Editor]] is permitted to use when creating or editing articles in the ''Lexicanum'' wiki. These sources are sometimes also referred to as ''official'', ''legitimate'' or ''canon'' sources but the term that should be used with reference to any work within the Lexicanum is nevertheless ''accepted sources'' (see also further down).
