"...the latest National Atlas includes electronic maps and services that are delivered online. We are using information presentation, access, and delivery technologies that didn't exist 30 years ago to bring you a dynamic and interactive atlas. But we have held fast to our tradition of producing the finest maps in the world. We think nationalatlas.gov™ is more useful than any bound collection of paper maps."
