While there have been several "common eras," as the term typically refers to the most current era humanity is in, the term has special meaning for the history of writing. The beginning of the Common Era, in regard to writing, is marked by the invention of the codex. The codex was a revolutionary form of physical writing that brought a new accessibility to reading. The Common Era brought a new wave of technology and information for writers and readers everywhere.
