Geologic Library and Data Center is the largest geological library and the only national data library in the U.S. Our 50,000-square-foot building contains some of the most difficult-to-find information on oil and gas exploration, carbon sequestration, lithium play research, geothermal projects, environmental projects, and saltwater disposal.

You can come to the library yourself to pull your data, or our librarian can pull it for you, and either make a copy or check out information.

Several generations of geologists have been coming here to find information for building their own proprietary maps they weren’t able to find anywhere else.
