Book excerpt: Established in the aftermath of World War II, UNESCO succinctly states its peace mission as well as its peaceful resolution to peace in its Constitution—constructing the “defenses of peace” in the minds of peoples on the “intellectual and moral” grounds. For more than seven decades, UNESCO has been consistently positioning peace as its unwavering core and ultimate goal through promoting international understanding and cooperation in and across its five major sectors of competence in education, natural sciences, culture, communication and information, and social and human sciences. Historical Dictionary of the United Nations Educational, Scientific and Cultural Organization (UNESCO), Second Edition contains a chronology, an introduction, and an extensive bibliography. The dictionary section has more than 700 cross-referenced entries on UNESCO’s initiatives, programs, projects, normative instruments, and partners over the past 76 years. This book is an excellent resource for students, researchers, and anyone wanting to know more about UNESCO.
