How control over information creation, processing, flows, and use has become the most effective form of power: theoretical foundations and empirical examples of information policy in the U.S., an innovator informational state.

A seminal book, impressive in its range, skill, and depth. Sandra Braman is one among a vanishingly small number of scholars with the skill and theoretical imagination to 'think' the information policy fields together. An important book for researchers, students, and policymakers. -- Steven J. Jackson, University of Michigan Change of State provides an important new reframing of the field of information policy and its key issues. The synthesis of established issues like intellectual property with emerging concerns like borders and identity makes Braman's book a major contribution to contemporary debates. And its clear organization and accessible writing style will make it an indispensable introduction for students and nonspecialists alike. -- Leah A. Lievrouw,, Professor, Department of Information Studies, University of California, Los Angeles
