The Carnegie Library archive collects, preserves, and provides valuable historical resources, intended to be protected in perpetuity about the history of Boulder County with an emphasis on the city of Boulder. Their care and preservation for the use of present and future generations is the principal responsibility of the Carnegie Library for Local History.
