Smithsonian place copyright free images online

There's a great deal of debate at the moment concerning copyright and how it affects us now and how it will affect us in the future. After the recent announcement (that actually deserves a blog post all of its own) that the Associated Press expects people to pay to use quotations of more than five words and thereby making a mockery of the fair use that we have all embraced, it's refreshing to see that there are others trying to make it easier to use material.

The Smithsonian Institution now has a flickr page with hundreds and hundreds of images with no copyright attached.

Example: Chicago Library floor plan, including two retiring rooms and two binderies!
