Computer Supported Cooperative Work (CSCW): The Journal of Collaborative Computing and Work Practices is devoted to innovative research in computer-supported cooperative work (CSCW). It provides an interdisciplinary and international forum for the debate and exchange of ideas concerning theoretical, practical, technical, and social issues in CSCW. The CSCW Journal encourages contributions that are mindful of the relations between social-science studies of cooperative work practices and their requirements with respect to computing technology. For example, we would urge social scientists who have made a study of a workgroup to spell out clearly what the implications of their findings are for design of appropriate computer support. Equally, we would urge computer scientists reporting on a technological innovation in, say, meeting room support, to spell out clearly how this work is motivated by studies of meetings or what new studies of meetings it suggests. What is required, is that contributions to the CSCW Journal have visible implications for CSCW: implications for the development of practice-oriented computing technologies.
