The new two-volume Zoological Society of San Diego centenary history is oustanding..possibly the best value book of ANY kind ive EVER bought.The two books come in a slipcase and then a presentation box..as a collector of ANY zoo book in ANY language,I own nothing to rival it for value for money.But heres the rub...if you are non- european it will cost you $72 to get it here and the book itself is only $49! In all fairness it is pretty heavy.
