The Commons is one of the more viable destinations on Flickr for information-seekers. The focus of The Commons, according to the description on its home page, is "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." The site allows users to tag photos and leave comments discussing their historical significance.
Aside from NASA's new gallery, The Commons features content from the Library of Congress, Smithsonian, and the New York Public Library, among many other institutions.
