Humanities Computing provides a rationale for a computing practice that is of and for as well as in the humanities and the interpretative social sciences. It engages philosophical, historical, ethnographic and critical perspectives to show how computing helps us fulfil the basic mandate of the humane sciences to ask ever better questions of the most challenging kind. It strengthens current practice by stimulating debate on the role of the computer in our intellectual life, and outlines an agenda for the field to which individual scholars across the humanities can contribute.
