Deletion of Quackenworth Publishing

Comment: It fails a straight , but I can't help thinking that if the Wikipedia:Naming conventions (books)#Note on notability criteria|notability criteria for a book is that it should be widely available and have an ISBN, then the publishers of widely available books with ISBNs are notable (http://www.amazon.com/gp/product/1933211547/ref=sr_11_1/104-1294653-8465542?%5Fencoding=UTF8 Amazon link

Comment: Can't see that any of their books have wikipedia articles. Only http://www.amazon.com/gp/product/1933211547/ref=sr_11_1/104-1294653-8465542?%5Fencoding=UTF8  Two http://www.amazon.com/gp/product/1933211555/qid=1149768830/sr=1-1/ref=sr_1_1/104-5147730-6565517?s=books&v=glance&n=283155 books only listed on Amazon. Website shows that most of their sales are likely to be direct and so not a wide readership. Seems to fail
