"Moving image footage of mental disease patients in the early part of this century and their treatment has long been one of the most requested items from the Historical Audiovisuals Collection of the National Library of Medicine (NLM). Most often, patrons wish to copy the footage for use in documentary programs for broadcast on television. In an effort to facilitate more efficient reference service to these items with an eye toward copying the footage, I have assembled this bibliography of pre-1950 mental disease moving images at the NLM. The listing of each title includes information necessary to make appropriate decisions regarding the copying of it, such as length, type of element, and copyright or other restrictions if known."
