Created by legislation in 1978, the Oklahoma Publications Clearinghouse of the Oklahoma Department of Libraries was charged with the responsibility "to establish an Oklahoma government publications depository library system for the use of the citizens of the State of Oklahoma; to collect state publications from every agency and to retain and preserve permanently copies of all such publications."
Publications received by the Clearinghouse from state government agencies are distributed to a network of seventeen depository libraries located throughout Oklahoma, as well as to the U.S. Library of Congress.
In 1985, the Oklahoma Department of Libraries initiated a program to microfilm state government publications. This program enabled all depository libraries within the Oklahoma Publications Clearinghouse system to receive copies of all available publications. Prior to 1985, only six libraries were designated as total depositories within the OPC system, and as such, received copies of all available publications.
