This article reports on a research project that investigated whether a recent version of the Schools Online Thesaurus (ScOT) provides an improvement on Schools Catalogue Information Service Subject Headings (SCISSH), or the contrary, for catalogue users searching by subject or topic. An experimental design was employed to evaluate the effectiveness of these two controlled vocabularies in quantitative terms. Test databases, hosted by the Schools Catalogue Information Service (SCIS) on their Voyager system, were used to represent different potential versions of a school library catalogue. A group of teacher librarians and students searched on these databases, their search results were rated for relevance and the performance of the databases was compared statistically.
