Flickr Commons was launched in January 2008 and its first partner was the Library of Congress. The goals of Flickr Commons are "to increase access to publicly-held photography collections, and to provide a way for the general public to contribute information and knowledge."
The Commons is a really useful and interesting repository of images that Flickr members can download, comment on, and tag.
Other contributing organizations to Flickr Commons include the Brooklyn Museum, the Powerhouse Museum (Sydney, Australia), and the Library of Congress.
