Matt Edgeworth (2014) has recently sought to consider how the computers used by archaeologists mediate the production and reproduction of archaeological knowledge (2014, 41) and the way the act of archaeological discovery has changed since his innovative ethnographic study of an excavation was carried out around 1990. In particular, he points to the way that the ‘site of discovery’ has in some instances moved to the computer screen from the physical world. He describes how the archaeological workplace has changed in the intervening years, and estimates that most archaeological project managers now spend an average of 70-80% of their time working in digital environments (2014, 43). He points to the increased pace and quantity of work that is consequently achieved, which may lead to an increasingly stressful working environment. That is not to say computers are involved across the board – as he says, some areas of archaeological work remain resistant to computerisation with excavation itself remaining a largely manual process despite the various attempts to use computers onsite (2014, 45). As a result, he suggests archaeologists typically move in and out of different modes of perception – from computer-based work to manual work and back again (2014, 47).
