Human Communication Eras

In a interesting paper, "Once in a hundred generations" Paul Berkman, writes,

"Once in a hundred generations, every 2000 years, an information technology threshold is reached that changes human capacity to manage and discover knowledge. Invention of the digital medium created such a paradigm shift and we are now faced with the challenge of sustaining the information products generated with this transformational technology."

Berkman goes on to describe the implications of this digital transformation for libraries, but the emergence of digital information has implications for learning and all parts of society that involves knol edge and information. This reminds us how big of a change we are experiencing.
