We all seem to know what Library 1.0 is/was since we continue to tell everyone how 2.0 we are, and some of us have even begun formulating lies for why we're past that and ready to declare ourselves 3.0.
But what about the past; what about the before time? How would we classify the earliest forms of librarianship? I'm trying to understand how Library 2.0 applies to history. At what point can we say that the ideas for a library existed?
