== Book reference == 

  - I have put the basic information about a book written on the subject of the article back in as the content is not promotional as claimed but is simply factual. It was referenced to a reliable source that is entirely independent of the zoo's own website and as stated in a previous discussion, this would have not been a reason for removal anyway. My edit does not state that the book is a 'good read', 'worth buying' etc which would be promotional content. It simply states a fact that a book has been written on the subject of the article by the owner. It is in line with other zoo sites, it is of potential interest to the reader and it is notable as not all zoo's have literature available about their development.
