The multilingual thesaurus was a landmark achievement in the electronic publishing of United Nations information, permitting the retrieval of official United Nations documents by topic in all six official languages of the Organization on the Official Document System (ODS).

However, for semantic tools to be entirely effective on the Internet, there is a need to re assess the traditional thesaurus approach and move towards a more modern technique that better suits the Web environment, such as the development of ontologies .

In addition, the Dag Hammarskjöld Library coordinated the creation and maintenance of the United Nations Bibliographic Information System (UNBIS) Thesaurus for all United Nations libraries, thereby providing a common controlled vocabulary for the description of United Nations documentation and externally acquired library materials.
