Coverley, M. (2006). Psychogeography. Harpenden, Pocket Essentials.
'Of course, it is through the media that psychogeography has gained a degree of mainstream acknowledgement and it is through the varied mediums of the novel and poetry, of film and internet, that it is able to leave a lasting record and to establish a tradition of its own. But, with the return of Robinson in Keiller's work, we are recalled finally to Defoe himself in whom the figure of novelist, pamphleteer and radical combined to provide a lasting template for a future psychogeography in which literary endeavour and political activism are once again inseparable.'
