Gorilla Pathology and Health: With a Catalogue of Preserved Materials consists of two cross-referenced parts. The first, the book itself, is a review of pathological changes and tissue responses in gorillas (Gorilla gorilla and G. beringei), with an emphasis on free-living animals, but also with reference to those in captivity. The comparative aspects are discussed, stressing the relevance of research to both gorillas and humans. What makes the publication truly unique, however, is the second part, a comprehensive descriptive catalogue of the location and nature of gorilla material in museums and scientific institutions throughout the world. This is of great consequence because free-living gorillas are strictly conserved with restricted access, so the location of a wealth of preserved tissues and other material that has been collected over the decades is a great benefit for research and study. This book can, and should, be used to gain cardinal knowledge regarding the biology and pathology of this genus. The combination of book and catalogue in this extensive compilation makes it an invaluable tool for all those concerned with the health, welfare, and conservation of gorillas, one of our nearest living relatives.
