Prior to the digital revolution that is currently underway, the printing press was the means by which words achieved permanence. Although spoken words maintain continuity over time, the passing of those words from generation to generation inevitably leads to change and reinterpretation; be that accidental or intentional. In one sense, the printing press is analogous to pre-digital photography. Once a photo had been taken there was a negative which was, in theory, “the original” picture. Similarly, what was/is printed cannot be easily erased.
