'...the book is of intrinsic interest to students and specialists in all areas of the EU, and valuable to historians and political scientists alike. Indeed the leitmotif of the need for academic cohesiveness in a truly comparative and theoretically grounded framework proves a vital lesson on how all future research in the field should be conducted. It is perhaps this more than anything that makes The History of the European Union a seminal piece in the undoubtedly crowded library of European integration literature.' - Matthew Broad, Journal for Contemporary European Research, Vol.6, No.2, 2010, 289-291
'...the goal of the book is worthy, the insights valuable ... It should appeal to EU integration scholars and advanced students coming at the topic from a number of disciplines.' - European History Quarterly, Vol. 40 No. 4. 2010, 728
