For preservation reasons, original analog and digital media may not be read or played back in the reading room. Users may visually inspect physical media, but may not remove it from its enclosure. All analog audiovisual media must be digitized to preservation-quality standards prior to use. Patrons may request digital copies of original analog media, but will be responsible for the cost of digital conversion, payable in advance. Turn-around time for such requests will depend on the size and scope of the project. Requests should be directed to Special Collections Public Services staff through the Ask Us! form.
