Geologic Records Center

With more than 180 years’ worth of research and data at its disposal, the ODNR Division of Geological Survey is an excellent source for information on Ohio geology. The Geologic Records Center (GRC) is the gateway to the Geological Survey’s library and archives, which are open to the public and hold hard-to-find historical documents, theses and dissertations, journals, field trip guides and more.

The GRC assists industry representatives, scientists, policymakers, educators, students and citizens-at-large in their efforts to access the Geological Survey’s extensive archive. Located at the ODNR main campus in Columbus, the GRC houses and distributes thousands of documents, including:

  • Technical reports and publications.
  • Popular publications and educational materials.
  • Geologic and topographic maps.
  • Natural resources maps (e.g., coal, industrial minerals, oil, gas).
  • Various records and data about specific sites throughout Ohio.

The GRC staff also fields questions from the public about Ohio geology. Visitors can access a suite of interactive mapping services.
