Upon approval by the Commission, the agency may remove certain record and nonrecord materials from its collections by gift to another public or nonprofit institution or by sale at public auction. This is a supplemental form of disposition beyond that recognized in the Public Records Act for the retention, copying, and destruction of public records, and it pertains only to those accessioned archives materials having a market value and which duplicate existing archival material, fall outside the scope of the archives collection policy, or have no further possible research value. All funds realized through sale by public auction must be placed in a special account to be used for improved access to and preservation of the state archives collections. The Commission shall report annually to the Budget and Control Board regarding these dispositions.
