S. F. M. Breitenbach & H. D. Gebauer: 199 pp., colour photo tables and maps, many surveys; Berlin 2013. This is our first anniversary volume! It has in-depth descriptions of over 350 cave/karst sites and also includes the historical surveys of the British expeditions in the 1940ties led by E.A.Glennie. Too many caves are unmapped yet. Consequently, this publication is a unique source for future explorers striving for improvements. In English language.
