"Informal International Lawmaking is a valuable addition to the growing body of work engaged with understanding how various sub- and transnational behaviors not directed by states are affecting international law and international cooperation." - Charlotte Ku, University of Illinois College of Law, American Journal of International Law

"All in all, the book is a pleasure, which is not always easy to achieve with an edited volume. Those with even passing interests in international institutions will benefit from contemplation of the conceptual approaches set forth here." - David Zaring, Opinio Juris

"Informal International Lawmaking provides valuable insights into the complexities of informal governance in world affairs and draws attention to aspects of informal cooperation that have remained underemphasized in existing research in the fields of international law and international relations. It is a book that all students of informal global governance should read and engage with." - Oliver Westerwinter, Review of International Organisations
