This book describes each mineral specie (in alphabetical order) and the mineral deposit where each mineral was found. The book also includes a section on the Geography of Discoveries (with many maps), and a Chronology of Discoveries. This volume is well illustrated with 186 color photos, plus B&W photos and crystal drawings. It also has an extensive bibliography with 761 references cited.
