Please explain what do you mean by

""reviews of his books to establish notability, as they aren't independent of the subject. For the article to be accepted and notability to be verifiable, you need non-trivial and independent sources""

why books' reviews are considered dependent? 
Can you give an example what is considered to be independent or non-trivial.
 Looking on many other biographies of professors in Wikipedia - I find many other with even less resources."
