    Abstract
    In one form or another, from a mental list in the mind of the librarian, to book catalogs, card indexes, and online information retrieval systems, some type of meta access has existed to guide library users through library collections. Over the last 40 years, these constructs of paper and wood evolved into Online Public Access Catalogs (OPACs). When the catalog shifted out of drawers and off of three by five cards to become a networked, universally accessible entity, its role in the library shifted as well. The OPAC competes with the World Wide Web, metadata registries, search engines, and more sophisticated database structures for attention. Amongst this assortment of access mechanisms, the purpose of the OPAC has become muddled. The OPAC has now become one information source among many and one of a number of portals for accessing library collections and beyond.

    Abstract
    Describes the Mercury project, at Carnegie Mellon Univ. Library, Pennsylvania, aimed at extending the scope of the OPAC to include other functions and services: access to full text and other online databases. The collection of databases (e.g. INSPEC, IBI/INFORM) forms the Library Information Systems (LIS2) and is accessible via a common user interface. Describes the distributed computer architecture of the Mercury electronic library with particular note of the document delivery service built into the system and designed to produce electronic documents in ASCII and bitmapped page image format, and in hardcopy format using electronic mail and print services. Pays particular attention to the principles underlying the design of the user interface and gives examples of the UNIX/Motif and VT100 search screens

    Abstract
    In 1991-92 the users of the National Technology Library of Denmark, the Helsinki Univ. of Technology Library, and the Technical Univ. Library of Norway were monitored to evaluate the way in which they usef the OPACs. The aim of the NORDINFO project was to promote end user accessibility by gathering valid information about the interaction between the users and the 3 systems. The main emphasis was on how the different types of users actually carry out their searches with special attention paid to multilingualism. Transaction log analysis was used to monitor the search process

    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.

    Abstract
    Library users continue to experience difficulty in using the online catalog, particularly in the area of subject access. This project describes a test of a new design for subject access to online catalogs. The new design requires a wide range of subject searching capabilities and search trees to govern the system's selection of searching capabilities in response to user queries. Is the performance of search trees superior to subject searching approaches chosen at random? This project is geared to make that determination

    Abstract
    Recording for the Blind and Dyslexic has been providing audio recordings of educational texts since 1948. In 1992, it initiated a project to develop an OPAC to allow institutional providers and individual borrowers to search its holdings of over 80.000 volumes. In 1993, a coordinated pilot project was begun to allow a limited test group of institutional sites and individuals the ability to use the catalogue ordering mechanism for document delivery. Describes the project concluding that, although the project was not considered a success, much insight was gained as a result of the efforts which will be of value in the development of an improved version of the OPAC

    Abstract
    Desicusses the user training programme of the Helsinki University of Technology Library in the light of an internordic monitoring project. In the project, the use of OPACs was evaluated by analyzing the transaction logs and it was concluded that end users do not exploit the various possibilities of OPACs. A large part of the material found in the collections in the library is not retrieved: misspellings, lack of truncation, inequate use of Boolean operators and wrong database choices lead to ineffective retrieval. Emphasis in the online catalogue training has been on the 'hands on' exercises and it appears that the training programme is not very effective in the area of subject searching. Presents reasons for this and discusses plans for the future development of the library user training programme

    Abstract
    Paper presented at the 14th biennal conference of IATUL, Cambridge, Mass., USA, 8-12.7.1991: new technologies and information services - evolution or revolution? Ed. by Jay K. Lucker and published by the British Library on behalf of the IATUL. The ETH-Bibliothek is the main library of the Swiss Federal Institute of Technology and the national centre for scientific and technical literature. Mostly there is no open access for the public. The ETHICS project was initiated to run library applications on the the library's own computer. The project is conceived as a multi-library integrated system whose separate units interrelate via a central database. The main function of the system is the online public access catalogue. Describes the specifications of ETHICS including interactive communication in German and French for storing and retrieving data. The subject index is maintained in French, German and English. Discusses retrieval by title words, subject retrieval and alphabetic retrieval. Outlines future developments

    Abstract
    Description of the online catalogue (OLCA) development abd the subject access potency (Controlled and free term indexing, classified approach, subject indication costs, Boolean searching). The subject access research needs are outlined as well as the measures to be taken towards putting the Delft University of Technology Library catalogues online (AUBID-SSX project, subjects access point file, quantitative evaluation) The importance of the use of controlled vocabulary is stressed. The incorporations of a concordance between subject headingsa nd the local library classification is described

    Abstract
    This paper describes a survey on how system vendors and libraries handled tagging in OPACs and discovery layers. Tags are user added subject metadata, also called folksonomies. This survey also investigated user behavior when they face the possibility to tag. The findings indicate that legacy/classic systems have no tagging capability. About 47% of the discovery tools provide tagging function. About 49% of the libraries that have a system with tagging capability have turned the tagging function on in their OPACs and discovery tools. Only 40% of the libraries that turned tagging on actually utilized user added subject metadata as access point to collections. Academic library users are less active in tagging than public library users.

    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
    Documents in digital and paper libraries may be arranged, based on their topics, in order to facilitate browsing. It may seem intuitively obvious that ordering documents by their subject should improve browsing performance; the results presented in this article suggest that ordering library materials by their Gray code values and through using links consistent with the small world model of document relationships is consistent with improving browsing performance. Below, library circulation data, including ordering with Library of Congress Classification numbers and Library of Congress Subject Headings, are used to provide information useful in generating user-centered document arrangements, as well as user-independent arrangements. Documents may be linearly arranged so they can be placed in a line by topic, such as on a library shelf, or in a list on a computer display. Crossover links, jumps between a document and another document to which it is not adjacent, can be used in library databases to allow additional paths that one might take when browsing. The improvement that is obtained with different combinations of document orderings and different crossovers is examined and applications suggested.

    Abstract
    Reports on a continuing project to study children's use of a graphically-based direct manipulation interface for science materials. The Science Library Catalogue (SLC), a component of project SEED, has been implemented in the libraries of 21 elementary schools in Los Angeles and will soon be implemented in a public library. The interface employs a hierarchical structure drawn from the DDC and implemented in HyperCard on the Macintosh. The study on the 2nd version of the interface indicates that children are able to use the Science Library Catalogue unaided, with reasonable success in finding items. Search success on the same topics on a Boolean command driven system was equivalent, but Boolean searches were faster. However, the Boolean system was more sensitive to differences in age, with 12-year-olds having significantly better success rates than 10-year-olds; and to search topic, with one set of questions being much easier to search than the other. On average, children liked the 2 systems about the same; the Boolean system was more attractive to certain age and gender combinations, while the Science Library Catalogue was more consistently liked across groups. results are compared to prior studies on the Science Library Catalogue and other online catalogues
