The article is devoted to the description of the thesaurus on information technologies developed within the framework of the target program for the development of information resources of the Department "Electronic Library of the Siberian Branch of the Russian Academy of Sciences". The thesaurus is actively used in the educational process of NSU students, as well as for automatic communication of documents in the electronic library created and operated at the FRC ICT. To implement the thesaurus, the Zthes data scheme was chosen, the main advantage of which is its compliance with the Z39.50 network protocol model, which allows not only to work with its own local thesaurus, but also to connect, if necessary, thesauri located on the network. New elements have been added to the Zthes data schema by the developers. Currently, the thesaurus is implemented in threelanguages (Russian, Kazakh and English) and contains over 20,000 terms.
