Great story about  the launch of a brand-new pilot project with Flickr, the enormously popular photo-sharing site.

More than 3,000 photos from two of the most popular collections are being made available on a new Flickr page, to include only images for which no copyright restrictions are known to exist.

“We want people to tag, comment and make notes on the images, just like any other Flickr photo, which will benefit not only the community but also the collections themselves.”
