This third (and final) edition of Bernard and Hyrsl's Minerals and Their Localities provides basic data (formula, crystal system, cleavage, cell dimensions, color, hardness, optical constants, geological environment, associations, etc.) for around 5,000 mineral species, along with the locality or localities, much like the last edition of Dana's System (1997) and the five-volume Handbook of Mineralogy (1990-2003). In many cases a reference is provided to articles in technical mineralogical journals. What separates it from Dana is the use of around 1,000 photos of specimens (typically study-grade examples), each photo printed about 2.7 inches wide. There are no crystal drawings. At the back is a useful alphabetical list of 9,500 mineral locality names with a (sometimes abbreviated) list of species for each.
