Book excerpt: Since the UN's creation in 1945 a vast nexus of global and regional institutions has evolved, surrounded by a proliferation of non-governmental agencies and advocacy networks seeking to influence the agenda and direction of international public policy. Although world government remains a fanciful idea, there does exist an evolving global governance complex - embracing states, international institutions, transnational networks and agencies (both public and private) - which functions, with variable effect, to promote, regulate or intervene in the common affairs of humanity. This book provides an accessible introduction to the current debate about the changing form and political significance of global governance. It brings together original contributions from many of the best-known theorists and analysts of global politics to explore the relevance of the concept of global governance to understanding how global activity is currently regulated. Furthermore, it combines an elucidation of substantive theories with a systematic analysis of the politics and limits of governance in key issue areas - from humanitarian intervention to the regulation of global finance. Thus, the volume provides a comprehensive theoretical and empirical assessment of the shift from national government to multilayered global governance. Governing Globalization is the third book in the internationally acclaimed series on global transformations. The other two volumes are Global Transformations: Politics, Economics and Culture and The Global Transformations Reader: An Introduction to the Globalization Debate.
