Our mandate

Library and Archives Canada (LAC) combines the holdings, services and staff of both the former National Library of Canada and the National Archives of Canada. As outlined in the Preamble to the Library and Archives of Canada Act, LAC's mandate is as follows:

  • to preserve the documentary heritage of Canada for the benefit of present and future generations;
  • to be a source of enduring knowledge accessible to all, contributing to the cultural, social and economic advancement of Canada as a free and democratic society;
  • to facilitate in Canada co-operation among communities involved in the acquisition, preservation and diffusion of knowledge;
  • to serve as the continuing memory of the Government of Canada and its institutions.

As of 2016, Library and Archives Canada has approximately 30 million photographic items in its collection, including photographic prints and photographic negatives, as well as more historic items (daguerreotypes, ambrotypes and autochromes), colour transparencies, slides and, lastly, some digital photographs.

Created in 1983 within the Department of Cultural Affairs of the City of Paris, the Atelier de Restauration et de Conservation des Photographies de la Ville de Paris (ARCP) implements the preservation and valorization policy for the City's photographic heritage, which represents about 13 million photographs, conserved in its museums, libraries and archives.

The ARCP, managed by Anne Cartier-Bresson, is composed of five sections - registration, preventive conservation, remedial conservation-restoration, reproduction and documentation - providing several services such as condition surveys and collections care advice, specific conservation treatment of historic or fine art photographs, preparation and protection procedures before digitalization, reproduction of original negatives and prints, technical assistance during exhibitions, exhibition curating etc.

The ARCP takes also part in advanced research and dissemination of knowledge in the field of photographic preservation and conservation, in France or abroad, offering specific training, welcoming interns, opening its documentation center to researchers, and publishing reference books as Le Vocabulaire Technique de la Photographie edited by Anne Cartier-Bresson (Marval/Paris Musées, 2008).
