Libraries, historical societies and history museums in Oklahoma may have special collections or archives pertaining to the state and to their local area. These places are often times the repository of the personal papers of individuals and organizations important to the locality. Expect to travel to see the material because the material is not available for InterLibrary Loan in almost every case. Each web site has information on hours of operation and visitor use policies. It's always a good idea to contact the library before making the trip.
