Trapped in the Net

"This is a major work of synthesis and insight that will prove invaluable not only to scholars and students but also to policymakers, large-system designers, and others concerned with the role of computers in society. Rochlin has mastered an amazingly broad body of literature, grasped its deeper implications, and presented his results in a highly readable form, well peppered with anecdote and narrative. He has also, and most importantly, hit upon the most important characteristic of the society-wide electronics infrastructures now being put into place: that such systems are socio-technical in nature and cannot be understood as mere hardware and/or software."--Paul N. Edwards, Author of The Closed World: Computers and the Politics of Discourse

Voice mail. E-mail. Bar codes. Desktops. Laptops. Networks. The Web. In this exciting book, Gene Rochlin takes a closer look at how these familiar and pervasive productions of computerization have become embedded in all our lives, forcing us to narrow the scope of our choices, our modes of control, and our experiences with the real world. Drawing on fascinating narratives from fields that range from military command, air traffic control, and international fund transfers to library cataloging and supermarket checkouts, Rochlin shows that we are rapidly making irreversible and at times harmful changes in our business, social, and personal lives to comply with the formalities and restrictions of information systems.
