EAPS Library Information
About Us

Mission Statement:

The major emphasis of the Earth, Atmospheric, and Planetary Sciences Library (EAPS Library) collection is in the following subject areas: Atmospheric Sciences, General Geology, Paleontology, Structural Geology, Sedimentology, Geoscience Teaching, Geophysics, Geochemistry, Mineralogy, Petrology, Engineering Geology, Environmental Geology, and Hydrogeology. The EAPS Library is a depository of the U.S. Geological Survey. Also, state geological survey material is collected from the various states. The collections and services of the EAS Library are available to the entire university community, though this library primarily supports the research and instructional activities of the Department of the Earth and Atmospheric Sciences' faculty, students, and staff.
