The care and preservation of the archival materials, a tenet of the Archives’ mission, is carried out by arresting deterioration and maintaining collections in as original condition as possible. Every effort will be made to provide the best possible environmental conditions, including control of temperature, humidity, lighting, and air quality. Provisions are to be made for the protection of collections from fire, theft, vandalism, natural disasters, and damage in transit. Established procedures are set up to handle all emergencies. Materials will be housed in archival-quality enclosures and stored in or on appropriate steel equipment. Materials may be reformatted for preservation and for access purposes.
