a. The 2011-2012 Edition Released in annual editions each containing 5-7 volumes, the Annual Review of United Nations Affairs is the only thorough annual survey of major developments at the United Nations. The 2011/2012 edition includes the full text of all General Assembly, Security Council, and ECOSOC resolutions from the 66th United Nations session (Sept. 2011 to Sept. 2012), along with other key UN documents, including selected progress reports from UN peacekeeping, peace-building, and political missions. This edition also includes six introductory articles written by expert contributors. These introductions offer invaluable guidance on the activities of various United Nations bodies, including the General Assembly, the Security Council, the Economic and Social Council, the International Court of Justice and Tribunals, the Secretariat, and the Peacekeeping and Peace-building Missions. The 2011/2012 edition also features a Foreword by Lord Mark Malloch Brown KCMG, former UK Minister for Africa, Asia, and the UN, and former United Nations Deputy Secretary-General and Administrator of UNDP. b. The set generally Since the publication of its first edition in 1950, the Annual Review of United Nations Affairs has stood as the authoritative resource for scholars, students, and practitioners researching the latest developments at the United Nations. From introductory articles on particular topics, prepared by experts on the relevant United Nations bodies, to the full-text presentation of reports and resolutions and the helpful subject index, ARUNA provides a comprehensive tour of each year's UN actions and debates. The expert selection of documents by Joachim Muller and Karl Sauvant and the topic-based organization of those documents make any researcher's task much easier than the vast searching and sorting required by the UN's website. The series' topic-based organization of the materials and subject index lend invaluable guidance to all researchers. Beginning with the 2010/2011 edition, detailed commentaries on the various UN bodies by experts on the relevant topics were also added to each annual edition, and the analysis provided in these commentaries has helped to make ARUNA a more complete resource for anyone engaged in research on the activities of the United Nations. ARUNA presents comprehensive documentation of the work of the UN on an annual basis, starting in September of each year with the beginning of the regular sessions of the General Assembly. Coverage of and commentary on the UN's key organs are provided, including the General Assembly, the Security Council, the Economic and Social Council, the International Court of Justice, and the UN Secretariat. In addition, selected reports of intergovernmental bodies and expert groups are included. ARUNA occupies a special place in the publications on the work of the UN, as it allows readers to obtain an overview of the principal developments in its key organs. This makes it an important reference source for policy-makers and academic researchers.
