W. W. Norton & Company and the American Political Science Association are pleased to announce the publication of the Centennial Edition of Political Science: State of the Discipline. Editors Ira Katznelson and Helen V. Milner of Columbia University sought to "reflect the vibrant, often contested, diversity of political science while chronicling the past decade’s scholarship and prompting thought about future directions." Breaking away from a traditional organization around the four major fields of political science, the editors chose to create a framework that focuses first on the state, followed by democracy, then agency, and concluding with means of inquiry. This volume is an important resource for all scholars interested in reading across fields and includes an essential unified bibliography.
