“This online database represents the fourth edition of the UNBIS Thesaurus and the first in all the official languages of the United Nations: Arabic, Chinese, English, French, Russian, and Spanish. The multilingual UNBIS Thesaurus, created by the Dag Hammarskjöld Library, United Nations Department of Public Information, contains the terminology used in subject analysis of documents and other materials relevant to United Nations programmes and activities. It is used as the subject authority of the United Nations Bibliographic Information System (UNBIS) and has been incorporated as the subject lexicon of the United Nations Official Document System. It is multidisciplinary in scope, reflecting the Organization's wide-ranging concerns.”
