Chasing Technoscience: Matrix for Materiality, edited by Don Ihde and Evan Selinger, is well-suited for at least two specific audiences: those familiar with the technoscience studies literature and looking for the current research of major authors, and those new to the field looking for material to supplement core readings. The book proceeds with special focus on four key technoscience figures: Donna Haraway, Don Ihde, Bruno Latour, and Andrew Pickering. An interview with each of these authors, comparative essays written by technoscience scholars, and an original article by each of the four primaries are included. The editors’ claim that Chasing Technoscience represents “a state of the art” look at the field is justified since, as I show below, the original pieces written by the four key figures represent samples of those authors’ major contemporary projects.
