    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
    Summarizes findings of an international study on information-seeking habits and preferences: With extensive input from hundreds of librarians and OCLC staff, the OCLC Market Research team developed a project and commissioned Harris Interactive Inc. to survey a representative sample of information consumers. In June of 2005, we collected over 3,300 responses from information consumers in Australia, Canada, India, Singapore, the United Kingdom and the United States. The Perceptions report provides the findings and responses from the online survey in an effort to learn more about: * Library use * Awareness and use of library electronic resources * Free vs. for-fee information * The "Library" brand The findings indicate that information consumers view libraries as places to borrow print books, but they are unaware of the rich electronic content they can access through libraries. Even though information consumers make limited use of these resources, they continue to trust libraries as reliable sources of information.

    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
