Governing Privacy in Knowledge Commons explores how privacy impacts knowledge production, community formation, and collaborative governance in diverse contexts, ranging from academia and IoT, to social media and mental health. Using nine new case studies and a meta-analysis of previous knowledge commons literature, the book integrates the Governing Knowledge Commons framework with Helen Nissenbaum’s Contextual Integrity framework. The multidisciplinary case studies show that personal information is often a key component of the resources created by knowledge commons. Moreover, even when it is not the focus of the commons, personal information governance may require community participation and boundaries. Taken together, the chapters illustrate the importance of exit and voice in constructing and sustaining knowledge commons through appropriate personal information flows. They also shed light on the shortcomings of current notice-and-consent style regulation of social media platforms. This title is also available as Open Access on Cambridge Core.
