‘Truths Universally Acknowledged’, where I try to make the case that a running series that’s the work of many hands, like Doctor Who, can’t be seen as a unified whole or as a set of individual books, so represents a distinct class of art, which I call an ‘unfolding text‘. Published in Third Person. 2009, MIT Press, edited by Pat Harrigan and Noah Wardrip-Fruin. (Buy from Amazon UK, US).
