Here is a sustained investigation into the human contexts of Information and Communication Technologies (ICTs), covering both research and theory in this emerging field. Authors Kling, Rosenbaum, and Sawyer demonstrate that the design, adoption, and use of ICTs are deeply connected to people’s actions as well as to the environments in which they are used. In Chapters One and Two, they define Social Informatics and offer a pragmatic overview of the discipline. In Chapters Three and Four, they articulate its fundamental ideas for specific audiences and present important research findings about the personal, social, and organizational consequences of ICT design and use. Chapter Five covers Social Informatics education; Chapter Six discusses ways to communicate Social Informatics to professional and research communities; and Chapter Seven provides a summary and look to the future.
