Photographs are three-dimensional material objects that exist in time and space and move through various social contexts. One of these contexts is constituted by the photographic archive in which they are preserved. An archive is an ensemble formed not only by photographs and their mounts, stamps and inscriptions, but also by card catalogues and inventory books, by the photo boxes and their spatial arrangement on the shelves according to the classification system of a specific photo collection as well as by digital instruments. They all interact within the archive's habitat. Thus, from the perspective of the material turn photo archives can be understood as ecosystems: open, dynamic and complex structures formed by different organisms which act and interact with each other and their surroundings. It is also a place where archivists and scholars operate. Their functional role within the system as a whole cannot be that of neutral custodians of (visual) truth – for they shape (photographic) documents with archival practices and technologies. The photo archive does not only provide (visual) information, but it is the result of sedimentation processes that produce and transform knowledge.
These, in brief, are the premises of the "Photo Archives" conference series, launched by the Photothek in collaboration with its international partners in 2009: an open-ended series of international conferences, dedicated to photo archives and the reciprocity and interaction between photographic records and academic disciplines. The first two conferences, Photographic Archives and the Photographic Memory of Art History I-II, were held respectively in the Kunsthistorisches Institut in Florenz and at the Courtauld Institute of Art in London (London, 16-17 June 2009; Florence, 29-31 October 2009). The proceedings were published in the volume of the same name. These conferences were followed up by Photo Archives III. Hidden Archives, organized by the Institute of Fine Arts in New York (25-26 March 2011). The initiative was then continued with Photo Archives IV. The Photographic Archive and the Idea of Nation, held in Florence on 27-28 October 2011--its proceedings were published under the same title in 2015--and the conference Photo Archives V. The Paradigm of Objectivity, organized in cooperation with the Getty Research Institute and the Huntington Library in Los Angeles on 25-26 February 2016. The next conference in the series, Photo Archives VI. The Place of Photography, will be held in Oxford on 20-21 April 2017.
