The 50th anniversary of the European Union in March 2007 is an ideal occasion for Government Professor Roy H. Ginsberg to release a new book. Demystifying the European Union: The Enduring Logic of Regional Integration (February 2007, Rowman & Littlefield) is Ginsberg#s fifth book on #the world#s greatest experiment in interstate reconciliation through regional integration.# The new book grew out of Ginsberg#s course, #Political Economy of European Integration,# introduced at Skidmore 20 years ago as the first of its kind in the United States. The EU began in 1957 with the signing of the Treaty of Rome by six European states. Romania and Bulgaria joined the EU in 2007, bringing the membership to 27 states. Although the EU is turning 50, Ginsberg says, #it remains a mystery to many in and outside Europe.# The book, designed to #demystify# the EU for both new and seasoned readers, begins with the foundation blocks of history, law, economics, and politics #to introduce readers to the origins and enduring logic of European integration.# Ginsberg then describes the EU as a #polity# before evaluating the effects of EU policies on Europeans and non-Europeans alike.
