The geological library has been in existence since 1966, having been founded, owned and operated by the Oklahoma City Geological Society (OCGS).  In late 2015, upon recommendation and affirmative vote by the Society’s Board of Directors and subsequently approved by a vote of Society membership, the assets of the library and the building in which it is housed, the OCGS Devon Geoscience Center were deeded over to a newly-formed, 501(c)(3) charitable entity, the Mid-Continent Geological Library, Inc. (MCGL).  The MCGL applied for and was granted charitable status by the Internal Revenue Service in June, 2016.  The library will forever remain the MCGL Devon Geoscience Center in tribute to a significant financial donation made to the OCGS by Devon Energy during the Society’s 2014 capital campaign to assist with acquisition of a building. Since that time the library has moved to Edmond and the building sold, thus financing the digital transformation of the library data.
