Thesaurus BNCF

Nuovo soggettario (NS), edited by the National Central Library of Florence, is the Italian subject indexing tool for various types of resources. It has been developed in compliance with the IFLA recommendations, and other international standards in the field of subject indexing. This tool has been created for general and specialized Italian libraries, and for museums, multimedia libraries, archives and documentation centres. The main component of the NS is a general thesaurus available on the web since 2007 (http://thes.bncf.firenze.sbn.it/ricerca.php). The thesaurus comprises nowadays approximately 52400 terms and it is updated on a regular basis.
