Deletion of Philip Coppens (author)

Comment: You need to show he meets  - so far there's no evidence for it. His use here could just show editors pushing him - and I think you are probably right, too many articles using him as a source in cases where he isn't a |reliable source

Comment: Read  "The person has created, or played a major role in co-creating, a significant or well-known work, or collective body of work, that has been the subject of an independent book or feature-length film, or of multiple independent periodical articles or reviews." But they'd have to be mainstream sources and in more detail than the Seattle review. I don't think his books can be seen as significant without discussion of them in mainstream sources
