The term computer-supported cooperative work (CSCW) was first coined by Irene Greif and Paul M. Cashman in 1984, at a workshop attended by individuals interested in using technology to support people in their work. At about this same time, in 1987 Dr. Charles Findley presented the concept of Collaborative Learning-Work.According to Carstensen and Schmidt, CSCW addresses 'how collaborative activities and their coordination can be supported by means of computer systems'. On the one hand, many authors consider that CSCW and groupware are synonyms. On the other hand, different authors claim that while groupware refers to real computer-based systems, CSCW focuses on the study of tools and techniques of groupware as well as their psychological, social, and organizational effects. The definition of Wilson (1991) expresses the difference between these two concepts:CSCW a generic term, which combines the understanding of the way people work in groups with the enabling technologies of computer networking, and associated hardware, software, services and techniques.The 'CSCW handbook' papers were chosen as the overall most cited within the CSCW conference <...> It led to a list of 47 papers, corresponding to about 11% of all papers.
