This book is about the principles behind the open government data movement and its development in the United States.

"This book is the culmination of several years of thinking about the principles behind the open government data movement in the United States. In the pages within, I frame the movement as the application of Big Data to civics. Topics include principles, uses for transparency and civic engagement, a brief legal history, data quality, civic hacking, and paradoxes in transparency." --Home page (viewed on Sept. 16, 2013).
