===Specific periods===
* [http://www.historyplace.com/unitedstates/childlabor/ Child Labor in America 1908] – 1912 by [[Lewis W. Hine]]
* [http://www.fdrlibrary.marist.edu/archives/collections/photographs.html Franklin D. Roosevelt Presidential Library and Museum] Thousands of on-line, copyright free photographs of Franklin and Eleanor Roosevelt, The Great Depression and the New Deal, and World War II.
* [http://www.gwpda.org/photos/greatwar.htm Photos of the Great War] many images of [[World War I]], scanned in from public domain resources. Slight usage notice, which is probably compatible with GFDL (requires attribution and link, as does GFDL, requests e-mail notice of usage).
* [http://greatwar.nl/kleur/kleur.html The Heritage of the Great War] has several colour pictures from World War I (likely all PD, since the effort taken to scan/reproduce them probably fails to qualify for being a derivative work).
* [http://digital.library.northwestern.edu/wwii-posters/ World War II Poster Collection] over 300 posters issued by US Federal agencies
