    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
    The ENQUIRE project forms part of a series of investigations on query expansion in the Okapi experimental text retrieval system. A configurable user interface was implemented as an evaluative tool and tested in two locations on two different databases: the library catalogue of The London Business SChool and the computing section of INSPEC. The system offered a range of possible strategies based on thesaural terms for reformulating queries. These could be initiated automatically by the system or interactively with the user. The formative phase of the evaluation established the appropriateness and usability of the interface as well as users' perceptions of the underlying functionality. The aim of the large scale field trial was to determine to what extent user would select thesaural terms suggested by the system to reformulate queries, and to evaluate the effectiveness of a new dynamic form of query expansion implemented for this project

    Abstract
    This short guide describes the process for creating a CD-ROM based üublic access catalog. The authors admit that the material will be outdated by the time of publication, because product specifics change so rapidly. The report is useful, but not completely thorough. Disadvantages to using CD-ROM for public access catalog are listed, but existing methods to overcome these hindrances are not mentioned. The paper also touches on the possibility that CD-ROM-based catalogs may be more than simply an extra service, that they may become full-service catalogs in themselves

    Abstract
    Describes a feasibility study funded by BLRDD to test a new concept in bibliographic control in OPACs based on the manifestation of the work. The research was conducted at Bradford University, leading directly from the QUALCAT project, and used bibliographic records supplied by OCLC. A new type of hierarchical bibliographic record structure was used to import sets of bibliographic records into a hierarchical relational database. This was used for an experimental Windows based OPAC. Much of the early part of the project was spent clarifying the practical and theoretical implications of the manifestations concept

    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
    The destabilizing influences of the Web, widespread ownership of personal computers, and rising computer literacy have created an era of discontinuous change in research libraries a time when the cumulated assets of the past do not guarantee future success. The library catalog is such an asset. Today, a large and growing number of students and scholars routinely bypass library catalogs in favor of other discovery tools, and the catalog represents a shrinking proportion of the universe of scholarly information. The catalog is in decline, its processes and structures are unsustainable, and change needs to be swift. At the same time, books and serials are not dead, and they are not yet digital. Notwithstanding widespread expansion of digitization projects, ubiquitous e-journals, and a market that seems poised to move to e-books, the role of catalog records in discovery and retrieval of the world's library collections seems likely to continue for at least a couple of decades and probably longer. This report, commissioned by the Library of Congress (LC), offers an analysis of the current situation, options for revitalizing research library catalogs, a feasibility assessment, a vision for change, and a blueprint for action. Library decision makers are the primary audience for this report, whose aim is to elicit support, dialogue, collaboration, and movement toward solutions. Readers from the business community, particularly those that directly serve libraries, may find the report helpful for defining research and development efforts. The same is true for readers from membership organizations such as OCLC Online Computer Library Center, the Research Libraries Group, the Association for Research Libraries, the Council on Library and Information Resources, the Coalition for Networked Information, and the Digital Library Federation. Library managers and practitioners from all functional groups are likely to take an interest in the interview findings and in specific actions laid out in the blueprint.
