If you don't mind me asking, would you say this book is worth it?
I own the first edition and it's an expensive yet essential part of my zoo library. It is a hardcover, over 400 pages, and works best as a reference book for the history of zoos. In fact, it is surely the #1 book ever written in regards to zoological history. There are 10 contributors and they write about the zoos of ancient times (Greek, Roman, Persian, Aztec, etc.) that takes up approximately the first 50 pages. Then there are whole sections on the zoos of Great Britain, Western Europe, Central-Eastern Europe and Russia, USA, Australia, Asia, India, Japan, Africa and South America. It is easily the most comprehensive zoo book ever written.
At the back of the book is a 20-page appendix listing all the major zoos in order of their opening dates. You can find obscure information, such as Bulgaria's Akvarium Varna's opening date of 1932, or that Sea World Durban in South Africa opened in 1959. The second edition is due on July 11th and it will contain a wealth of updated information, including a new section on the history of Canadian zoos written by Brent Huffman.
I own hundreds of books about zoos and
Zoo and Aquarium History: Ancient Animal Collections to Zoological Gardens (Vernon Kisling, 2001) must be pretty close to being the finest zoo book ever published.
