This book brings together three great motifs of the network society: the seeking and using of information by individuals and groups; the creation and application of kwledge in organizations; and the fundamental transformation of these activities as they are enacted on the Internet and the World Wide Web. Of the three, the study of how individuals and groups seek information probably has the longest history, beginning with the early information needs and uses studies soon after the Second World War. The study of organizations as kwledge-based social systems is much more recent, and really gained momentum only within the last decade or so. The study of the World Wide Web as information and communication media is younger still, but has generated tremendous excitement, partly because it has the potential to reconfigure the ways in which people seek information and use kwledge, and partly because it offers new methods of analyzing and measuring how in fact such information and kwledge work gets done. As research endeavors, these streams overlap and share conceptual constructs, perspectives, and methods of analysis. Although these overlaps and shared concerns are sometimes apparent in the published research, there have been few attempts to connect these ideas explicitly and identify cross-disciplinary themes. This book is an attempt to fill this void. The three authors of this book possess contrasting backgrounds and thus adopt complementary vantage points to observe information seeking and kwledge work.
