The Encyclopedia of Caves and Karst Science contains 350 alphabetically arranged entries. The topics include cave and karst geoscience, cave archaeology and human use of caves, art in caves, hydrology and groundwater, cave and karst history, and conservation and management. The Encyclopedia is extensively illustrated with photographs, maps, diagrams and tables, and has thematic content lists and a comprehensive index to facilitate searching and browsing. The essays, written by an international team of specialists, progress from general concepts to deeper understanding with jargon explained for the non-specialist. Each essay is fully referenced, with suggestions for further reading and cross-references to related articles. The Encyclopedia of Caves and Karst Science is an up-to-date reference work for undergraduate and graduate students, researchers and professional hydrogeologists, planners, environmental scientists and conservationists. It is also the ideal place for the keen amateur cave scientist to begin finding out about unfamiliar topics. While not intended as an atlas, cavers and the wider public will find discussion of all the world's important cave and karst areas.
