Deletion of A.R. Horvath

Comment: per Guy. Of course the third-party sources provision applies, as  is a foundational policy of Wikipedia in the first place, and new authors ''especially'' should only be included when they exist, to prove that they are notable. Obscure, by the way, is not the same thing as un-notable
Stance: delete

Comment: If as is, the article is more about the author's book than about him; the inclusion of material blatantly promoting the book ("back cover blurb"?) as well as prominent, gratuitous linkage to the author's website and online forum fall under  (soapbox: self-promotion and advertising). Significantly revamping the man's bio and shifting focus away from the book would perhaps save things, but not as it stands now
