- Abstract
- Describes the availability, use and value of Z39.50, an international standard which allows a librarian accessing a database on one computer platform to search an OPAC hosted on another computer with a totally different database structure. Experiences of those working with the standard are given, and its use by the European Union IRIS project to link 6 major Irish research libraries is examined. Despite some problems encountered with different forms of author cataloguing and possible competition from the WWW, the standard is seen as possessing considerable strengths, for example in searching different catalogues and presenting the results in a standard format on screen, which justify the continuing interest of librarians

- Abstract
- Experiences with retrieval in OPACs suggest that there are major problems for the users of such systems, such as choosing the 'correct' subject access vocabulary, narrowing or broadening the set of items retrieved regarding the search interest. Such problems relate to two facts: (1) that in the early OPACs subject access has not been considered seriously enough and (2) that the complexity of the topic has not been really recognized. Using a typology of users' questions it is demonstrated which requirements musts be met by a successful online subject access. Improvements of subject access tools are primarily aimed at, pinpointing the interplay between the different subcomponents of any subject facility: a) the features of the indexing languages used; b) the indexing principles used; c) the design and structuring of the database; and d) the possibilities of the technical retrieval facility, the search mode, and query languages. The contribution summarizes the manifold interactions between the four subcomponents listed. Any successful retrieval will heavily depend on the design of these components considering their interactions.

- Abstract
- An experimental online catalog was developed that provided searchers with several different subject searching strategies. Analyses of retrieval test data suggest that searchers expect alphabetical searches to provide lists of assigned subject headings conceptually related to their topics of interest. System designers can now respond to their expectation by incorporating LCSH-mr in online catalogs

- Abstract
- In the last decade a discussion has been going an in the Division of Bibliographic Control of the International Federation of Library Associations and Institutions (IFLA) about the principles of cataloguing. This discussion was initiated by the widespread replacement of the card and list catalogues by Online Public Access Catalogues (OPACs) since 1980. In this paper we discuss the role of subject cataloguing in three important documents that are the results of this discussion. Our conclusion is that the interest in subject cataloguing has grown remarkably, but is still not an the level it deserves given the fact that a great part of all searches in OPACs are subject oriented.
- Content
- 1. Introduction In this paper we address two questions: 1. What is the position of subject indexing in the thinking of the library world after the publication of the Functional Requirements for Bibliographic Records (1998)? 2. Is this position in accordance with the requirements of the users searching for documents about a given subject? Research Shows that searching an a topic (i.e. subject access) is an important, even predominant type of end-user searching of library catalogues and even more so of other bibliographic databases. Between one third and two thirds of all OPAC searches are probably subject searches (Large & Beheshti, 199%). Taking into account different ways in which searching an a topic is implemented in library catalogues (subject headings, classification, keywords only) the percentage may be even higher. For example title word searching may be a substitute for subject searching if no better tools are available. In the light of this it is not surprising that the Functional Requirements for Bibliographic Records (FRBR) (1998) pays attention to subject searching, as well as the Functional Requirements and Numbering of Authority Records (FRANAR) (2003). Also the Statement of International Cataloguing Principles: Final draft of 19 December 2003, which is the result of the first First IFLA Meeting of Experts an an International Cataloguing Code mentiong subject access as a function of cataloguing (Statement, 2003). In this paper we discuss the ways these three documents deal with subjects.

- Abstract
- This paper reports on the successful introduction of a sophisticated online catalogue system at the library of the Scott Polar Research Institute, Cambridge, using the Muscat program package. The system provides to both end-users and library staff a choice between boolean searching on keywords and access using relevance feedback based on free text in English, mixed with UDC classification numbers. The system is implemented on an IBM 3084 computer. Significant benefits from the application of relevance feedback are reported with 10,000 records on file.

- Abstract
- This research investigated the ways in which different levels of knowledge about a topic can affect searching for information on that topic in a library online catalog. It was found that people with high levels of knowledge use more search expressions, including more general and nonproductive expressions, than low-knowledge users. It was also found that high-knowledge users employed more search expressions that had not been contained in their statements of information need than low-knowledge users. These differences in vocabulary use and search expression formulation may be of interest to designers of online catalogs as they attempt to increase the responsiveness of catalog systems to the needs of individual users

- Abstract
- This study aimed to determine if the searching behaviour of remote users of LIAS, Penn State's online catalogue differed from those using the OPAC within the library. More than 1.000 searches done by remote users (those accessing the system via either dial-access or the university's computer network) were compared to more than 1.000 searches done by in-house users. Each search was duplicated step by step and analysed according to a pre-determined set of criteria. Although few dramatic differences were found between the 2 groups, there were enough subtle differences to generate interest. In general, remote users are the more sophisticated searchers, bearing out the assumption that remote users seem to have a better conceptual knowledge of how an information system should operate. On the other hand, they struggle more with the procedural details of how to use the OPAC. Dial-access users seem to constitute a unique group of users: their searches are often quite different than those done by either network or in-house users

- Abstract
- Subject queries were extracted from 3 universities' online catalogues and analysed to determine the extend to which they matched subject headings in the LCSH. Computer analyses show that nearly 25% of the subject queries entered by online catalogue users are exact matches of LCSH. Yet, manual analyses show that, even though a user matches or closely matches LCSH-mr, the citations retrieved by this vocabulary are not necessarily satisfactory. Sometimes the closest LCSH-mr is not at all pertinent to a user's topic of interest. This study presents reasons why close matches of LCSH-mr are not always satisfactory and suggests approaches to finding the best matches of the catalogue's controlled vocabulary

- Abstract
- Searching information retrieval systems is a highly interactive, iterative process that cannot be understood simply by comparing the output of a search session (the 'search product') to a query stated in advance. In this article, we examine evaluation goals and methods for studying information retrieval behavior, drawing examples from our own research and that of others. We limit our review to research that employs online monitoring, also known as transaction log analysis. Online monitoring is one of few methods that can capture detailed data on the search process at a reasonable cost; these data can be used to build quantitative models or to support qualitative interpretations of quatitative results. Monitoring is a data collection technique rather than a research design, and can be employed in experimental of field studies, whether alone or combined with other data collection methods. Based on the the research questions of interest, the researcher must determine what variables to collect from each data source, which to treat as independent varaibles to manipulate, and which to treat as dependent variables to observe effects. Studies of searching behavior often treat search task and searcher characteristics as independent variables and may manipulate other independent variables specific to the research questions addressed. Search outcomes, time, and search paths frequently are treated as dependent variables. We discuss each of these sets of variables, illustrating them with sample results from the literature and from our own research. Our examples are drawn from the Science Library Catalog project, a 7-year study of children's searching behavior on an experimental retrieval system. We close with a brief discussion of the implications of these results for the design of information retrieval systems
