Deletion of The 85 Ways to Tie a Tie

Comment: The book passes  for at least having multiple non-trivial reviews by third parties, including "Scientific American" magazine.  True, Google gives me only 850 or so general hits, which boils down to only 257 distinct hits, but there are several reviews in this lot beyond the dozens of book sales.  There are also several listings of articles based on the book, which is apparently a derivative of knot theory, which in turn also meets .  Downsides are the article does appear to be an ad, and it lacks sources and ''verification in the article itself''.  The real problem I'm having however is in the nomination, which doesn't actually state grounds for deletion.  "Seems a bit suspicious"?  Reads "like" an advert.  "May" be copyvio.  One fake Interwiki?  I have no idea how to check the Interwiki, that's my bad, but none of the politely-worded commentary shows any failure of WP policy and guidelines
