A pilot project with the Library of Congress,
Your opportunity to contribute to describing the world's public photo collections
There are already some interesting collections up there, like News in the 1910s and 1930s-40s in Color.
The key goals of this pilot project are to firstly give you a taste of the hidden treasures in the huge Library of Congress collection, and secondly to how your input of a tag or two can make the collection even richer.
You're invited to help describe photographs in the Library of Congress' collection on Flickr, by adding tags or leaving comments
It will be interesting to see the range of tags and comments people take the time to put forward (but I'm not sure that comments like "neat train picture :)" are doing much for our understanding of LOC image collections!)
