Very scarce. One of the great topographical mineralogies, Die Minerale des Harzes attempts to give a complete mineralogical description of the Harz mountains of Germany, which has for centuries provided many remarkable mineral specimens. Beginning around 1880, Lüdecke devoted himself to his project, using not only his own extensive reference collection, but a number of other public and private ones as well; thus the amount of study material at the authors disposal was very large. Besides his own competent observations, the author gives a summary of earlier literature and work of other mineralogists. The book becomes, therefore, a complete series of monographs covering the important mineral localities of the region. Arrangement of the species is by a chemical classification, with detailed discussion of crystallization, occurance, and mineral associations. In the case of common species, such as galena, a greater geological description of the particular regions involved is given. The plates show figures of the notable species together with their spherical projections. A chart of the region showing the mineral viens is added as are detailed ones for Andreasberg and Clausthal.
