In operation since 1958, the Colorado River Indian Tribes Library is known as the first Tribally funded library in the United States. Instrumental in its development were the late Dr. Spencer Hatch and his wife Emily. In tribute to their oustanding contributions to the Colorado River Indian Tribes, the Tribal Council adopted Dr. & Mrs. Spencer Hatch as honorary members on December 1, 1962. This action reflected the gratitude of Tribal Members for both Dr. Hatch and Emily, and has been the only time constituents of the Caucasian race have been adopted as honorary members of the Tribe.
In 1966, books were moved from the first library, at the old Agency tribal office to the present facility. In September 1970, as part of the National Indian Days Celebration, the Library and Museum building were dedicated with Mrs. Hatch as Master of Ceremonies. It is the first triball owned and operated library which includes a complete archive and indian information section in the United States.
