The UNBIS Thesaurus is a multilingual database of the controlled vocabulary used to describe UN documents and other materials in the Library's collection.
The UNBIS Thesaurus grows as new topics are introduced to the agenda of the Organization and evolves as the language in the UN documents shifts over time. Controlled vocabulary makes subject searches possible by identifying documents on the same concept, even as terminology changes.
UNBIS Thesaurus terms are used in the UN Digital Library. In addition, other UN programmes, funds and regional commissions use the UNBIS Thesaurus for description of bibliographic materials and web content.
The UNBIS Thesaurus is available online in the six official UN languages, and for download in csv or ttl formats.

Created by the Dag Hammarskjöld Library, 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 third edition (1995) of the Thesaurus was trilingual; it was a major undertaking to have the nearly 7,000 terms translated into three additional languages. The first, preliminary, online version was launched in November 2001.
While the current version features some significant improvements, it too represents but a stage in the development of the Thesaurus, and comments on this product are welcome.
