An argument that the material arrangements of information—how it is represented and interpreted—matter significantly for our experience of information and information systems. Virtual entities that populate our digital experience, like e-books, virtual worlds, and online stores, are backed by the large-scale physical infrastructures of server farms, fiber optic cables, power plants, and microwave links. But another domain of material constraints also shapes digital living: the digital representations sketched on whiteboards, encoded into software, stored in databases, loaded into computer memory, and transmitted on networks. These digital representations encode aspects of our everyday world and make them available for digital processing. The limits and capacities of those representations carry significant consequences for digital society. In The Stuff of Bits , Paul Dourish examines the specific materialities that certain digital objects exhibit. He presents four case studies: emulation, the creation of a “virtual” computer inside another; digital spreadsheets and their role in organizational practice; relational databases and the issue of “the databaseable”; and the evolution of digital networking and the representational entailments of network protocols. These case studies demonstrate how a materialist account can offer an entry point to broader concerns—questions of power, policy, and polity in the realm of the digital.

A sociotechnical investigation of ubiquitous computing as a research enterprise and as a lived reality. Ubiquitous computing (or ubicomp) is the label for a “third wave” of computing technologies. Following the eras of the mainframe computer and the desktop PC, ubicomp is characterized by small and powerful computing devices that are worn, carried, or embedded in the world around us. The ubicomp research agenda originated at Xerox PARC in the late 1980s; these days, some form of that vision is a reality for the millions of users of Internet-enabled phones, GPS devices, wireless networks, and "smart" domestic appliances. In Divining a Digital Future , computer scientist Paul Dourish and cultural anthropologist Genevieve Bell explore the vision that has driven the ubiquitous computing research program and the contemporary practices that have emerged—both the motivating mythology and the everyday messiness of lived experience. Reflecting the interdisciplinary nature of the authors' collaboration, the book takes seriously the need to understand ubicomp not only technically but also culturally, socially, politically, and economically. Dourish and Bell map the terrain of contemporary ubiquitous computing, in the research community and in daily life; explore dominant narratives in ubicomp around such topics as infrastructure, mobility, privacy, and domesticity; and suggest directions for future investigation, particularly with respect to methodology and conceptual foundations.
