The Mudd Library houses materials in the fields of earth and planetary geology, geobiology, geophysics, geochemistry, and environmental science.
The Library's collection is especially strong in materials dealing with California, the western United States, and North America.
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 California, Arizona, and Nevada, and USGS geologic maps of California, including USGS Open-File Reports and CDMG Open-File Reports. Numerous map collections are now available freely online. Please visit the Maps LibGuide page for these resources.
The Library also houses the division's theses, with print copies through 2002. Theses after 2002 are hosted exclusively on our CaltechTHESIS repository (browse by option). You can also browse by author, year, advisor and more.

LibGuides, created by SpringShare, are a content management system used at thousands of libraries worldwide.
Librarians use it to curate and share information, knowledge, and resources, based on their institute's primary areas of research and their users. They are not a comprehensive guide to all available resources.
LibGuides are just that..."guides" to using a subject-specific area or topic. Further exploration is encouraged by the library user.
LibGuides can be difficult to maintain, as links can and do change frequently, resources come and go and more.
All of our Library's LibGuides are available here.
