Carl sez, "The Smithsonian is up and running on Flickr Commons ... the photos are all labeled "no known copyright restrictions" and the photos are high-res. I was particularly intrigued by the Dibner Library of the History of Science and Technology, with photos of famous scientists and inventors. We should all congratulate the Smithsonian on a *big* step forward!" Link (Thanks, Carl!)
