Finding Geologic Maps Geologic maps for most areas of Pennsylvania are available in the Preliminary Geologic Atlas of Pennsylvania (QE157.A3 4th.ser. A61). Maps are black & white at a scale of 1:62,500. Maps in this atlas are filed by quadrangle name. If you don't know the name of the quadrangle, you can use this index to Pennsylvania quadrangle maps to determine the name or look it up using the GNIS (Geographic Names Information System). Geologic maps of individual Pennsylvania counties are available in A Geological Hand Atlas of the Sixty-Seven Counties of Pennsylvania (QE157.A16 X). Digital versions of geologic maps for selected areas of Pennsylvania are also available.

Finding Topographic Maps The EMS Library has an incomplete set of topographic maps for Pennsylvania only at 1:24,000, 1:62,500 and 1:250,000. These maps are located in the EMS Library maps collection. They are arranged by call number (G3820.S24G4) and sheet name. The Maps Library in Paterno Library collects topographic maps for all 50 states. Many topographic maps are now available online. You can find topographic maps at the following web sites: TopoZone - Search by place name or latitude and longitude. Various scales provided. TerraServer - View topographic maps, relief maps, and aerial photographs. Maptech MapServer - Search by place name. Various scales provided. Maplink - Locate topographic maps (and map names) using map indexes. The USGS maintains an online list of all its topographic maps. Finding Mine Maps Few libraries collect mine maps but state and federal agencies frequently do. National Mine Map Repository - This agency maintains copies of abandoned US mine maps on microfilm. Their database is not accessible via the Internet but the staff will search their holdings upon request. West Virginia mine maps - This website has scanned images of mines in West Virginia. Kentucky Mine Mapping Information System Pennsylvania Mine Maps Department of Environmental Protection Mine Map Repositories The Earth and Mineral Sciences Library has a set of Bituminous coal mine maps of Pennsylvania (see catalog record), created by the WPA during the 1930's. Sample images of these maps are available for Altoona and Philipsburg. These maps are based on 15-minute topographic quadrangles, divided into nine sections. (For example, Altoona1 represents the northwestern corner of the Altoona 15-minute quadrangle. Altoona9 represents the southeastern corner of the quadrangle.) Index to Maps of Abandoned Mines in Pennsylvania -This index contains over 11,000 entries for maps of abandoned mines in Pennsylvania.   Finding Fire Insurance Maps Fire insurance maps show the outlines of buildings along with their construction details (e.g., brick, wood, etc.). One of the most prolific publishers of fire insurance maps in the United States was the Sanborn Company. Most original fire insurance maps at Penn State are housed in the Special Collections Library. Monochromatic microfilm is also available in the News and Microforms Library. Find fire insurance maps in the catalog by browsing or searching for Insurance, Fire - [location] - Maps.
