I asked Chuck about a week ago if he had an old periodic table lying around that he could lend to me. He found this one in a box in the basement and said I could have it. Told me he was using the “updated” version and no longer needed this one. So simple to use, too. http://www.flickr.com/photos/78046474@N06/10367797084/lightbox/
