What is Public Archaeology?

I have been following a thread this week on the World Archaeology Congress list serve debating the meaning of Public Archaeology.  A simple definition for me:

Public Archaeology is about engaging the public at some level in what we as archaeologists do in order to share our sometimes esoteric data with a wider audience.  Its about translating the nuances of our discipline to a broad audience in an effort to raise the conscience of people, particulalry those in the local community where we work.  Our research can be very mundane to the outside world.  We have to deliver our message in a format that has wide appeal.  We want to educate.  This is what the Johannes Kolb Archaeology and Education Project is all about.
