Why study OPAC use? Questionable role of the OPAC in terms of relevance, use and value Are there new ways of information seeking and are they changing the way patrons are searching the OPAC? How seriously should we consider calls to abandon LCSH cataloguing? What about the “classical functions of bibliographic control”? Are South African students following the same searching behaviour patterns shown elsewhere?
UCT implemented the Web OPAC in 1999 (Aleph® ILS system from Ex Libris) Since 2006 OPAC search records have been stored as Oracle tables Transactional Log Analysis (TLA) was rejected as a tool for data analysis in favour of SQL and other reporting tools No attempt was made to study or measure search success, nor measure user satisfaction
