A special collection of German, Polish, and Russian language books, maps and reports in the US Geological Survey Library has an interesting and unusual history. The so-called 'Heringen Collection' came from Nazi Germany. Many of these items were captured from libraries, offices and even private homes as the German Army advanced into neighboring countries. In the last days of the war, these maps, reports, photos and other records were sent from the Military Geology offices in Berlin to the safety of a deep potash mineshaft in Heringen (Werra), in Hessen, Germany. A group of US Army soldiers found these lost records of the Third Reich. When removed from the Heringen mine, those records that dealt with the earth sciences, terrain analysis, military geology and other geological matters were sent to the USGS, and eventually came to reside at the USGS Library. The printed papers and books were mostly incorporated into the main collection, but a portion of the materials have never been cataloged, calendared or indexed. These materials have many current uses, including projects of value to citizens in their nations of origin.
