Kasaalan WPNO LE addresses the question of whether a subject is notable enough to justify an entry in Wikipedia It is independent of whether a source is reliable enough for WPRS as far as I can tell from the WPNO LE entry and its links   I agree with you on the writers POV but put that aside for now I want to get the verifiability issue out of the way If its not verifiable we cant use it and nothing else matters   WPVERIFIABILITY is one of the cornerstones of Wikipedia Is a citation to a book verifiable if WP editors cant check it because its only in  libraries in the world
