http://flickr.com/photos/library_of_congress/ The Library of Congress has partnered with Flickr to publish two large image collections, Web 2.0-style. The idea is to take advantage of "crowdsourcing," using input from many people around the world. In this case the hoped-for benefit is improving textual descriptions of each image. One collection consists of news photos from the 1920s, the other of color images from the 1930s and 40s.
