In 2010, the Saxonia-Freiberg-Stiftung in Freiberg in Saxony acquired the bulk of the photographic estate of the engineer Wolfgang Schreiber (1940–2005). Its major component consists of nearly 4,500 framed stereoscopic slides whose main focus was documenting the late era of ore mining, especially in Saxony and the Harz Mountains. The article presents the holdings of photographs that Schreiber took from the mid-1970s to the mid-1990s, which have been catalogued by the foundation and then digitized in cooperation with the German Photographic Collection in the Saxon State and University Library (SLUB) Dresden through the State Program for Digitization for Science and Culture of the Free State of Saxony and is currently being published online by the SLUB.
