"Since there are different sources of information for Harry Potter canon and sources do, on occasion, conflict with one another, the following guide is to be used on the Harry Potter Wiki. In order to simplify the different areas that exist as sources for canon information in the Harry Potter universe we have devised a three tier system summarised below. Please remember any type of fanon, information created by fans using the Harry Potter characters, is not considered canon at all and must be marked as such, unless made canon by a legitimate source."@en . . . . . . . . . . . . . . . . . . .

Please remember any type of fanon, information created by fans using the Harry Potter characters, is not considered canon at all and must be marked as such, unless made canon by a legitimate source. Although there are different levels of canon, this does not mean relevant information cannot be included in situations where there are conflicting canon sources. Ambiguous continuity should always be noted. If an \"official\" canon source has been chosen, (e.g. J. K. Rowling has said that a fact was a mistake and it was meant to be something else), the information from the conflicting source should still appear in the article in the \"Behind the scenes\" section. Basically put, everything is canon unless specifically contradicted by a \"higher\" source."@en . .
