OFF-SITE MOTION PICTURE STORAGE

国家医学图书馆有权保存其 收藏。在NLM持有的资产中，估计有52,000部视听作品， 包括大约4000部历史电影。收藏品 被认为是国家资源，因为许多书目不是 可在其他美国生物医学图书馆找到。彩色电影胶片 在正常储存温度下特别容易褪色。 这些保存母版需要在稳定的温度下保存 大大低于其他图书馆资料的推荐标准， 包括缩微胶片。 该项目的目标是：L)获得一个场外金库 长期(永久)保存色彩运动母版 推荐严格、稳定的影视作品 可以达到温度和相对湿度的水平， 维护；2)确保以环保方式运输货物 图书馆和场外储存地点之间的保存馆长； 以及3)为图书馆提供一个机制，以便迅速召回 根据需要和按需永久保存的母版保存胶片。

The National Library of Medicine has a mandate to preserve its collections. Among NLM's holdings are an estimated 52,000 audiovisuals, including approximately 4,000 historical motion pictures. The collection is considered a national resource since many of the titles are not available at other U.S. biomedical libraries. Color motion picture film is particularly susceptible to fading at normal storage temperatures. These preservation masters need to be kept at stable temperatures considerably lower than those recommended for other library materials, including microfilm. The objectives of this project are: l)to acquire an off-site vault for the long-term (permanent) storage of preservation masters of color motion picture film and audiovisuals in which stringent and stable recommended levels of temperature and relative humidity can be achieved and maintained; 2) to ensure environmentally-controlled transport of shipments of preservation masters between the Library and the off-site storage site; and 3) to provide the Library with a mechanism for the prompt recall of master preservation film from permanent storage as needed and on-demand.
