This paper presents results from a research project sponsored by the Smithsonian Institution to construct and operate a low-cost subzero temperature storage vault for photographic and manuscript collections. It uses conventional walk-in freezer technology and passive moisture control methods to achieve large savings in both construction and ongoing operational costs.
