In 1977, the Indian Arts and Crafts Board completed an extensive renovation of the museum, allowing more space for the permanent collection and traveling exhibits from other tribal people from throughout the United States.
That same year, the museum launched a partnership with Oklahoma schools to offer free educational tours for groups of students wishing to study Plains cultures.
