A few years back we embarked on an expedition into the rapidly transforming landscape of data research, the narratives of big data and the practices emerging with novel data resources, tools and new directions of social and cultural inquiry. This book represents our own experiences and impressions of this journey. We were out there on unfamiliar and at times even uncharted territory. Often we depended on the help of more learned colleagues who generously shared their knowledge, gave us directions or helped with problems. Many of them became authors for this book and we would like to thank them for trusting us with collecting their contributions and presenting them in a joint volume. The editors wish to thank the Utrecht Data School staff Thomas Boeschoten, Irene Westra, Iris Muis, Daniela van Geenen and Gerwin van Schie for their input and for providing an intellectually stimulating work environment. With the Utrecht Data School we have created a place where ambitious and enthusiastic students can meet to join us in this exploration. We are grateful for having the rare opportunity of conducting research together with students from whom we can learn so much and whose insatiable curiosity is an inspiration as well as a constant reminder of why we became teachers in the first place. Our gratitude extends also to the Institute of Cultural Inquiry and the open access fund at Utrecht University for enabling us to make this book open access. A special thanks to William Uricchio, Fernando van der Vlist and Eef Masson for their helpful comments and advice at various stages of the editing process. Finally, we are particularly grateful to Nicolás López Coombs for helping us with the editing and the formatting of the book, but most importantly for keeping an eye on our timeline. Mirko Tobias Schäfer & Karin van Es Anywhere but in their office, 2016 This book is an important contribution towards meeting the challenges of the platform-driven, data-fuelled world in which we have all come to live.
