a. New in the 2010-2011 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.

With the publication of the 2010/2011 edition and going forward, the ARUNA series will be enhanced by the inclusion of six new introductory articles written by expert contributors. Readers will find that the detailed commentary of the new introductions will 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 2010/2011 edition also features a Foreword by former United Nations Secretary-General Boutros Boutros-Ghali.

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 Müller 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.

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.
