Library of Congress photos on Flickr
The Library of Congress has joined the social tagging scene, putting a selection of photos from its collections on Flickr. Users are invited to view and tag the photos, which have no known copyright restrictions. For more information about this project, see this recent entry in the Library of Congress Blog. Currently, there are 1500 photos in a set called “News in the 1910s” and 1615 photos in a second set called “1930s and 1940s in Color.”
