- Abstract
- The study of subject access to UK academic library catalogues was based on a questionnaires end out during Summer 1991. 86 out of a possible 110 questionnaires were returned. All universities and polytechniques now have OPACs which are progressing well towards comprehensive bibliographical coverage of their libraries' stocks. The MARC format is now widely used. Subject access strategies are usually based on either Library of Congress Subject Headings or inhouse indexing systems but almost half the OPACs studies have no separate subject searching option based on subject indexing is expensive and future subject indexing strategies are best based on pre-existing controlled vocabularies. Strategies authority control is essential. A limited range of software strategies is recommended including the need to limit search results

- Abstract
- Reports the result of survey of users of the library catalogues in Cambridge University Library carried out in 1992 which aimed to discover the uses of the catalogues and the user's understanding of them. Describes the projects objectives, gives a history of the Cambridge University Library, describes the catalogues and details the conduct of the survey and results

- Abstract
- Reports results of an investigation, undertaken at Sheffield University, Departmant of Information Studies, UK into the effects of postings information (the display on the screen of the number of references in the retrieved sets) on searching behaviour. Linked online searches were conducted, on the LISA database on CD-ROM, with and without postings information. Performance in terms of the number of relevant references, precision and recall was not significantly different whether postings information was available or not; but searches with postings information took more time and more sets were viewed than in searches without postings. Searchers thought that the lack of postings information had affected 90% of their searches. Proposes that training should place greater emphasis on the value of postings information at different stages of the search and should optimize the searching behaviour of those with different searching styles

- Abstract
- W.S. Cooper's utility theory was used to evaluate end user and mediated searching of online and CD-ROM databases. The searches were conducted by 510 end users, using MEDLINE. The relevance of the references and the usefulness of the documents retrieved were examnied. The study also assessed the perceived value to end users of the information retrieved. Mediated online searching cost 3 times as much as end user CD-ROM searching, but was only about twice as effective in terms of user satisfaction; user convenience should be a high priority for the information provider and mediated CD-ROM searching may be the best compromise currently available as regards cost effectiveness and successful information retrieval for end users
