The purpose of the master's thesis is to create thesaurus from subject heading list of Pionirska - The Centre for Jouth Literature and Librarianship. The main object of this work are prefined and in the themed facets subject headings. On the basis of existing subject heading list with the help of global method we selected list of controlled descriptors and also defined non-descriptors. These were assigned to the newly created facets and under-facets thesaurus. Among the descriptors and non-descriptors we made links, so that we have established hierarchical, equivalence and associative relationships. Revision of subject heading list will serve Pionirska and all those who deal with subject description of youth literature. It will allow easier assignment of more precise subject headings and influence the production of Manual for Youth Literature Quality Reading. Construction of thesauri for fiction represents a long-term and complex project. With certain adjustments and new attributes (facets) subject headings we wanted to draw attention to the problems subject descriptions of literary material on a systematic way.
