The Geophysical Laboratory and Department of Terrestrial Magnetism have a joint library with over 40,000 volumes (including books, journals, and maps) as well as online journals and databases. The collection supports advanced research in the physical and earth sciences. Particular subject strengths include geophysics, geochemistry, seismology, petrology, mineralogy, mineral physics, geobiology, physical chemistry, astronomy and astrophysics.

The Library's special collections include holdings in the history of geomagnetism, volcanology, petrology, physical chemistry, and early 20th Century exploration and travel.

The Archives embrace the administrative records of the Department of Terrestrial Magnetism (founded 1904) and Geophysical Laboratory (founded 1905); records of the research vessel "Carnegie" (1909-1929); and 30,000 photographs documenting DTM's World Magnetic Survey (1904-1946), in addition to other field and laboratory studies of both departments.
