<br/><br/> "Copying is the engine of civilization: culture is behavior duplicated. The oldest copier invented by people is language, by which an idea of yours becomes an idea of mine. The second great copying machine was writing. When Sumerians transposed spoken words into stylus marks on clay tablets more than 5,000 years ago, they hugely extended the human network that language had created." (SMITHSONIAN) This article discusses the history and significance of copying and copiers.
