Look what's new!! Library of Congress is running a pilot offering historical photograph collections through Flickr. Doing so gives the Library of Congress a welcome opportunity to share some of our most popular images with a new visual community.
The Library of Congress invites you to tag and comment on the photos, and will also welcome identifying information—many of these old photos came to LoC with scanty descriptions!
To view the photos on Flickr, go to: http://www.flickr.com/photos/Library_of_Congress. You do not need a Flickr account to view the images; you would need to sign up for a free account to add comments or tags.
