The approximately 170,000 photographs (about 10% in colour) taken by the United States Farm Security Administration and Office of War Information are available here.
An absolutely fascinating collection and a useful resource for gaming in the USA in the late Pulp/WW2 era. For example it has over four hundred photos from Essex county, Massachusetts, ready to drop into a Call of Cthulhu game set in Lovecraft Country. The collection is organised both geographically (for the half with such information) and by a tree structure of subjects.
