Book excerpt: This volume presents the proceedings of ECSCW 2013, the 13th European Conference on Computer Supported Cooperative Work. Each conference offers an occasion to critically review our research field, which has been multidisciplinary and committed to high scientific standards, both theoretical and methodological, from its beginning. The papers this year focus on work and the enterprise as well as on the challenges of involving citizens, patients, etc. into collaborative settings. The papers embrace new theories, and discuss known ones. They contribute to the discussions on the blurring boundaries between home and work and on the ways we think about and study work. They introduce recent and emergent technologies, and study known social and collaborative technologies. With contributions from all over the world, the papers in interesting ways help focus on the European perspective in our community. The 15 papers selected for this conference deal with and reflect the lively debate currently ongoing in our field of research.
