Tag historical photos from the Library of Congress on Flickr.

The Library of Congress recently posted 3,100 photos from their collection to the social photo site Flickr. In this joint project, registered users can comment on photos, add notes to the photos and even create tags to help digitally organize this collection.

This pilot project includes photos from two main collections:

The 1930s-40s in Color:

These vivid color photos from the Great Depression and World War II capture an era generally seen only in black-and-white. Photographers working for the United States Farm Security Administration (FSA) and later the Office of War Information (OWI) created the images between 1939 and 1944.

and News in the 1910s:

Welcome to the daily news scene from almost a hundred years ago, as photographed by the Bain News Service in about 1910-1912. We invite your tags and comments! Also, lots more identification information. (Most of these old photos came to the Library of Congress with very little description.)

This is a marvelous collection, and most of the photos don’t have any known copyright restrictions.
