An annual publication aimed at zookeepers and workers around the world. Each Yearbook is divided into three main sections. The first is devoted to the year's special topic. Section 2 covers new developments in the zoo world, for instance in breeding, husbandry and research, hand-rearing, buildings and exhibits. Section 3 is a reference section with information on zoos, aquaria and bird parks of the world, breeding lists and rare animal census, studbooks and registers.
Please note that the yearbook is nowadays published by Wiley who impose a 2-year embargo on direct sales by booksellers. This means that volumes published less than 2 years ago are only available as part of a subscription package with Wiley. Volumes published more than 2 years ago can be obtained through NHBS.
