About the UNESCO Thesaurus

The UNESCO Thesaurus is a controlled and structured list of concepts used in subject analysis and retrieval of documents and publications in the fields of education, culture, natural sciences, social and human sciences, communication and information.

Continuously expanded and updated since its first edition in English (1977), the Thesaurus has been translated into French and Spanish (1983–1984). A second revised version was released in 1995. Russian was added in 2005 and Arabic in 2020. Concepts are organized into 7 broad subject areas subdivided into 72 microthesauri, compliant with the ISO 25964 standard for thesaurus construction.

The Thesaurus is primarily used for indexing and retrieving documents in UNESDOC, UNESCO's digital library.
