New Books Added to my Reference Library

I recently found a book at the Henderson Library titled, Rockhounding Nevada (A Guide to the State’s Best Rockhounding Sites. ) Even though most of the sites listed in this book are well north of Clark County, this is a good book for anyone interested in collecting rocks, minerals, fossils, and gems in Nevada. In addition, I added a PDF Guide To Nevada's Historical Markers.  It provides information on the locations of the physical markers and shows the marker texts for 270 statewide historical sites; and a A Field Guide to Biological Soil Crust of Western U.S. Drylands: Biological soil crusts (BSCs) are an intimate association between soil particles and cyanobacteria, algae, microfungi, lichens, and bryophytes (in different proportions) which live within or on top of the uppermost millimeters of soil. The most identifiable forms being lichens and bryophyes. Click on the Site Reference Library tab, top right to learn more.
