'Jonas Tallberg and his co-authors have collected a uniquely refined dataset of transnational access to almost 300 international bodies over time, which forms the backbone for the first systematic explanation of transnational design. This path-breaking study will change our understanding of global governance.' Liesbet Hooghe, University of North Carolina, Chapel Hill and VU University, Amsterdam

'The Opening Up of International Organizations is the most comprehensive analysis of the rapid rise and role of transnational actors in global governance. Skilfully combining different theoretical and methodological approaches, the authors show how international organizations have opened themselves to private actors in order to better accomplish their tasks. Perhaps the biggest surprise in this important book is the 'paradoxical centrality' of states rather than civil society in this process.' Duncan Snidal, University of Oxford

'The Opening Up of International Organizations is social science at its best. The book is methodologically rigorous, theoretically innovative and of utmost political relevance. Jonas Tallberg and colleagues show convincingly that international organizations open up for nonstate actors since they need their involvement to fulfil their increasingly demanding tasks.' Michael Zürn, Social Science Research Center, Berlin
