- Abstract
- Subject queries were extracted from 3 universities' online catalogues and analysed to determine the extend to which they matched subject headings in the LCSH. Computer analyses show that nearly 25% of the subject queries entered by online catalogue users are exact matches of LCSH. Yet, manual analyses show that, even though a user matches or closely matches LCSH-mr, the citations retrieved by this vocabulary are not necessarily satisfactory. Sometimes the closest LCSH-mr is not at all pertinent to a user's topic of interest. This study presents reasons why close matches of LCSH-mr are not always satisfactory and suggests approaches to finding the best matches of the catalogue's controlled vocabulary
