This book examines how and to what extent academic research in politics and international studies has had 'impact' - in doing so, it also considers what might characterise 'world leading' research impact. 'Overall, this book provides a fascinating insight into the role of impact in inter>national affairs. It provides a nuanced discussion of impact and the varied role that public and media engagement can play. The discussion of characteristics identi>fied from the top-scoring 2014 case-studies provides many important and practical insights into the way impact was communicated. This, alongside the deep dive into impact in the discipline (chapter 4), makes the book essential reading for impact professionals in the UK as well as for researchers in International Relations.'--Bella Reichard, Newcastle University, International Affairs
