The Tobin Map International Geological Collection of the Walter Geology Library consists of more than 47,000 maps and map texts arranged geographically, following the general outline of the Library of Congress G (Geography) classification schedule. If you would like to see these maps online, you can look at a small sampling of the Tobin Map International Geological Collection. Reference our Maps Research Guide to find instructions on how to access specific maps in our collection.
The collection aims for worldwide coverage of maps on geology and related subjects, but is particularly strong in maps of Texas and select U.S. and foreign areas of geologic interest. With the Map Room of the Perry-Castañeda Library, it serves as a federal map depository for U.S. Geological Survey maps, having an almost complete set of the series maps published by this agency.
We also have a map scanner at located at a computer station and a drafting table located in the map room.
