Book excerpt: The forces of globalization are shifting our world, including the public sector, away from hierarchy and command and control toward one of collaboration and networks. The way public leadership is thought about and practiced must be, and is being, transformed. This volume in the "Transformational Trends in Governance & Democracy" series explores what the shift looks like and also offers guidance on what it should look like. Specifically, the book focuses on the role of "career leaders" - those in public service - who are agents of change not only in their own organizations, but also in their communities and policy domains. These leaders work in network settings, making connections and collaborating to create public value and advance the common good. Featuring the insights of an authoritative group of contributors, the volume offers a mix of scholarship, from philosophical discussions to conceptual models to empirical studies that, taken together, will help inform the transformation of public leadership that is already underway.
