“The key goals of The Commons on Flickr are to firstly show you hidden treasures in the world's public photography archives, and secondly to show how your input and knowledge can help make these collections even richer. ... Under "The Commons," cultural institutions that have reasonably concluded that a photograph is free of copyright restrictions are invited to share such photograph under their new usage guideline called "no known copyright restrictions."  If you go to http://www.flickr.com/commons/usage/ and scroll down, you will see a very impressive list of participating institutions.
