Rob Kling, his research interests, and his advocacy were at the center of a movement in analytical inquiry and empirical research that he called ‘social informatics’. The movement he fostered has grown to encompass a widening and interdisciplinary interest in research that carefully examines the ways in which information and communications technologies (ICTs) are bound up in everyday social and organizational structures. The purpose of this ebook is to extend his work, whose research interests, and advocacy were at the center of a movement in analytical inquiry and empirical research now known as ‘social informatics’ following his unexpected death in May 2003.
