The collection is open for research use. Physical Access: Researchers must use microfilm copy. Researchers must handle unprotected photographs with gloves. Researchers must use reference copies of audiovisual materials. When no reference copy exists, the Archives Center staff will produce reference copies on an "as needed" basis, as resources allow. Technical Access: Viewing the film portion of the collection without reference copies requires special appointment, please inquire; listening to audio discs requires special arrangement. Do not use original materials when available on reference video or audio tapes.
