When thinking about the history of photography, many will think about the annual exhibition catalogues of the Photographic Society, London. Fortunately, the talented individuals at De Montfort University have scanned and digitized all of the catalogues dating from 1870 to 1915. Currently the database contains over 45,000 records, which include detailed records of all the exhibits, reproductions of all the catalogue pages, all of the pictures of the photographs that were printed in the catalogues, and reviews of the exhibitions. Visitors can perform a detailed search across all of the catalogues, or just browse them by date. For those who might be working on a similar digital collection, the site also provides detailed information on the project, its methodology, and its execution.
