Although published seven years ago, I don't think this book has been previously mentioned on ZooChat. Those interested in the history of the Paris zoos might like to know about the book:- Les Zoos de Paris: Histoire de la Menagerie du Jardin des Plantes, du Jardin Acclimatation et du Zoo de Vincennes (Jean-Michel Derex; 2012)
I saw this book for the first time at ZooHistorica earlier this month; unfortunately, I am not aware of an English translation.
