“Key Documents on the Reform of the UN Security Council 1991-2019” brings together primary source documents reflecting the political, legal and academic discussions of the United Nations Security Council reform, in particular the Council’s membership and decision-making, as they have taken place since 1991. Earlier discussions from the late 1940s through 1991 are covered insofar as they offer a useful contribution to the current debate. This extensive collection, curated by a leading authority, is intended to be representative of the debate as a whole without bias, faithfully reflecting the positions of various stakeholders, global participants and civil society. This important work will be an indispensable resource for researchers and students, bringing together hundreds of documents produced during more than three decades by governments, UN bodies, universities, think tanks and individual authors in a single, comprehensive volume.
