Nuovo Soggettario Thesaurus

"Il Nuovo soggettario, curato dalla BNCF, è lo strumento italiano di indicizzazione per soggetto. Dopo la conclusione di una prima fase sperimentale e la pubblicazione del prototipo (gennaio 2007), il sistema è sottoposto ad evoluzione e costanti verifiche anche per garantirne un buon grado di coerenza, manutenzione e colloquio con i propri utenti. Il Thesaurus multidisciplinare viene via via incrementato tramite aggiornamenti semestrali e grazie alla partecipazione di altre istituzioni.
