From Flickr comes The Commons, a project that seeks to catalogue public photography collections from around the world. The Commons invites cultural institutions to share relevant collections in one place; as of this write up, there are over 100 participating museums, libraries, and other institutions. The collection includes a number of historical photographs (both portrait photographs and photographs of documents and illustrations) as well as contemporary photographs. Visitors can browse this collection by participating institution, or conduct a text search for the whole collection Many participating institutions have extensive albums included in their individual Flickr account for easy browsing. With participants ranging from UC Berkeley's Department of Geography to the Finnish Museum of Photography to the Internet Archive Book Images collection, The Commons offers something of interest for everyone.
