Abstract
The subject of this article is the preservation of processed blackand-
white photographic records in libraries. Since silver gelatin photographic
films and papers have been around for about a century, and
since by far the largest number of black-and-white photographic images
are silver gelatin images, knowledge of the properties of these records
is extensive. Factors that may affect their stability are, for the most part,
well known.published or submitted for publicatio
