Oklahoma Vertical Files are a collection of newspaper clippings, brochures, association newsletters and programs, pamphlets and other ephemera organized into two types of files - Biography files and Subject files. The files are housed in two separate locations - the Oklahoma Collection in the Oklahoma Department of Libraries building, first floor, and the Cartwright Library located in the basement of the State Capitol building. The Biography files include information about Oklahoma people. The Subject files include information about places, things, and events particular to Oklahoma or of interest to state government and policy researchers. The best way to see our Oklahoma Vertical Files is to come visit us at both our locations. We are open to the public each weekday, 8:00 to 5:00. Our files do not circulate, but there are copy machines available for your use at both facilities.
