Over the past thirty years, significant shifts in technology, political ideologies, and policy goals have resulted in an environment in which public libraries face the highest expectations to serve community needs against unprecedented political, economic, and policy challenges. Drawing on two decades of original research conducted by the authors, this book provides a data-driven examination of the interrelated impacts of political discourse and public policy processes on public libraries and the ways in which they are able to serve their communities, explaining the complex current circumstances and offering strategies for effectively creating a better future for public libraries.
