This book contains the refereed proceedings of the 4th Scandinavian Conference on Information Systems (SCIS), held in Oslo, Norway, in August 2013. Participants were invited to discuss experiences of "digital living" within a multitude of empirical settings, covering questions like e.g. "how do people relate to each other when interaction is mediated through social networks?" or "what are the societal effects of ICT becoming ubiquitous in everyday situations?". The 6 papers accepted for presentation at the conference were selected from 18 submissions and address "digital living" from different perspectives.
