'Making a strong case for interdisciplinary layering as a way to represent the many layers - physical, social, aesthetic - of the city, Fraser's visionary book is as much a meditation on the future of the digital humanities itself as it is on the city as an object of humanistic inquiry. He cogently charts a course for how humanists will employ thick mapping as a way to practice the digital humanities.' David J. Staley, Associate Professor of History and Adjunct Associate Professor of Design, Director of the Goldberg Center at The Ohio State University, USA
