With millions of photos accessible at the click of a mouse, the archive is a rich resource for anyone seeking images related to U.S. history and world events. Approximately ten million images are available, and because most of the photos were never published, the collection contains many never-before-seen pictures. Users can search by keyword, browse by decade, or explore featured events, people, or places. Names of photographers and the dates that photos were taken are identified. With images ranging from the 1750s to the 2000s, the site will be popular with users wanting images with historical context (Reference & User Services Quarterly, Fall 2010).
