This is the third book in the DATA Browser series of critical texts that explore issues at the intersection of culture and technology. The site of curatorial production has been expanded to include the space of the Internet and the focus of curatorial attention has been extended from the object to dynamic network systems. As a result, curatorial work has become more widely distributed between multiple agents, including technological networks and software. This upgraded "operating system" of art presents new possibilities for online curating -- even to the extreme of a self-organising system that curates itself. The curator is part of this entire system but not central to it. This book explores the role of the curator in the face of these changes.
