This enlightening collection of essays attempts to describe and analyze the essence of the European Union (EU). The volume honors Alberta Sbragia, a noted scholar of the EU. Much of the discussion addresses what the EU is not—the contributors make it clear that the EU is not a state or a government or an international organization; there is less discussion of what the EU actually is. The analyses range from Sbragia’s conceptions of the EU as multilevel governance and not government, to comparative federalism of a sort, and to the meshing of supranationalism above the member states to intergovernmentalism among member states. . . One intriguing chapter compares four EU administrative styles (Anglo American, Napoleonic, Germanic, and Scandinavian) and reveals the difficulty of developing a uniform theoretical vision and policy. These four approaches are quite varied, and the Scandinavian administrative approach presents the most compatibility between administration and politics at both the national intergovernmental level and the supranational level. Summing Up: Recommended. Graduate students, researchers, faculty, professionals.
