We are photograph conservators and have been building a library on the technical history of analog photography. Our professional need was for in-depth, technical information on the wide variety of photographic processes encountered in a private practice. We have added the growing literature on photograph conservation and collected in the fields of technology, photo chemistry, criticism and history. Over the years we have diligently searched out and purchased both individual items as well as collections, all with a focus on the technical history of traditional analog photography. Along the way, we acquired many monographs that helped us to expand our knowledge of individual artists as well as the histories and movements of the nineteenth and twentieth centuries. Although the monographs on individual artists were not the primary focus of our Library, there are now significant holdings of valued monographs on photographers from Richard Avedon to Edward Zerbe.
