This volume presents the proceedings of ECSCW 2015, the 14th European Conference on Computer Supported Cooperative Work, organized by the University of Oslo, Norway. The conference provides a venue for exploring novel, open and critical approaches to the multidisciplinary nature of social and collaborative technologies and work practices, critically reviewing new and established theories and research, forever committed to high scientific standards, both theoretical and methodological. These proceedings consist of 14 full and 3 exploratory papers, which reflect the lively debate currently ongoing within the CSCW field, focusing on work and enterprise and the challenges of involving various types of people like citizens, patients and software developers into collaborative settings. The blurring boundaries between home and work are explored and recent and emergent new technologies supporting collaborative work are introduced. With contributions from all over the world, the chapters provide interesting perspectives, helping to focus the European perspective within the CSCW community. This collection will be of interest to researchers and practitioners alike as it combines an understanding of the nature of technology within both the workplace and wider society
