Members of the entire Caltech community have access through GPS to our extensive online database of mineral and rock collections, to reprints and preprints of our scientific papers, and to a library of printed and electronic materials important to the fields of earth and planetary geology, geophysics, geochemistry, seismology, and paleontology.
The division is pleased to maintain these resources and make them available for the purpose of advancing scientific research and understanding.
The GPS Library's collection is especially strong in materials dealing with California, the western United States, and North America. The library is a depository for the publications of the U.S. Geological Survey (USGS) and the California Geological Survey (CGS), and it also collects relevant publications from the geological surveys of other states and from selected foreign surveys.
Special collections include geologic field-trip guidebooks of western North America (with an emphasis on the area between the Pacific Ocean and the Rocky Mountains), USGS topographic maps of the western United States, USGS geologic maps of California (including those published as USGS Open-File Reports), CGS Open-File Reports, and the division's theses.
The GPS Library is located at 201 North Mudd Laboratory and is open Monday through Friday, 8 a.m. to 5 p.m. The library's resources are also available digitally through the GPS Library website.
