"Wilken and Goggin’s edited collection is a valuable addition to the literature on locative media. By combining an international perspective with a wide range of topics, this book helps further our understanding of the potential impacts of these new technologies. One of the true strengths of this book is how it combines cultural, political, and economic areas of focus, and it will be a valuable resource for anyone studying the emergence of new mobile technologies." -- Jordan Frith, North Carolina State University, USA
