- Abstract
- The proliferation of online public access catalogs (OPACs) requires some systematic rationale for the comparative evaluation of their designs. Considered as an indexing application, the OPAC can be analyzed by three features: the variety of bibliographic data processed, the kinds of indexes constructed, and the ways in which the indexes are searched. No one configuration appiles to every library research project with equal efficacy or likelihood of satisfying queries. However, the rationale proposed can compare and evaluate alternative library computer catalogs in term of the library's understanding of the relationship between the library's collections and their use

- Abstract
- To an overwhelming extent, storage and retrieval systems were designed for information intermediaries who were specialists in formal, controlled documentation languages (e.g. classification systems, indexing languages) and who were then trained to utilize the query language of each retrieval system. However, with the advent of the microcomputer, there now exists, in the information retrieval industry, an obvious will to tackle both the professional and the personal information markets, as evidences by their more sophisticated yet more user-friendly systems and by the design and marketing of all sorts of interface software (front-end, gateway, intermediary). In order to make full advantage of these systems, the user must be able to master three different languages: the natural language of the discipline, the indexing language, and the system's query language. The author defines and characterizes each of these languages and identifies their issues and trends in the IR cycle and specifically in public online search services. Finally he proposes a theoretical model for the analysis of IR languages and suggests a few research avenues

- 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
- Recent research shows that users of online catalogs find subject searching difficult, that characteristics of subject searches are qualitatively different from those of known-item searches, and that some design features of online catalogs appear to perform better than others for topical searching. It has been recommended that system designers develop different approaches, or interfaces, for different kinds of searching. This paper revies available design techniques from a subject searching perspective, including various methods of indexing bibliographic records, processing and correcting user input, searching the database, and displaying search results. The review concludes that there are many alternative approaches, each with strenghts and weaknesses, and combining techniques in new ways may have unknown results, but many promising methods are nonetheless available now to make more effective use of the subject information in current bibliographic records.

- Abstract
- Describes the function and problems of the traditional card catalogue compared with a computerised catalogue. Examines library cataloguing with the computer, linked to rules for subject cataloguing, as well as the oppor-tunities offered by computerised title entries, the transfer of data from outside, data base structure and indexing. Also looks at techniques for searching catalogues with computers, including search rules with Boolean operators, searches restricted to specific fields of free search in all fields for a vague concept. Other topics cover the essential principles of the OPAC, its information functions, mail box function and hardware configuration.

- Abstract
- Traditional subject cataloguing hampers subject retrieval in central catalogues, because of the lack of a common indexing and retrieval language in these catalogues. This study investigates the possibilities to use the various individual subject access systems, present in the catalogues, for subject access. A search procedure based on 'citation pearl growing' and 'user relevance feedback', which can be applied in a public access interface to central data bases, has been developed. From an experiment it can be concluded, that automated expert assistance, provided with a search strategy, will improve search response for unexperienced searchers. It reduces the number of zero-hits and increases the number of relevant items retrieved

- Abstract
- The degree of variability in the percentage of subject searching in an online public access catalog (OPAC) among branch libraries of one university was studied. A full semester's worth of transactions was analyzed, not sampled. The time units used were hour of the day, day of the week, and week of the semester. The findings show that subject searching varies from a low of 22% to a high of 74% over the hours of a day. Variability for the days of the week ranged from 17% to 64%, and for the weeks of the semester variability ranged from 12% to 70%. Valuable management information on the utilization of the OPAC within each brach library and among all the branch libraries is provided through numerous charts and graphs.

- Abstract
- Searching behaviour in a university library is studied using a holistic approach, encompassing the use of bibliographic tools and shelf browsing. The present study is designed as the first half of a 'before and after' study to permit the evaluation of the impact of a future online catalogue on users' searching behaviour. A combined methodology was devised: searchers were encouraged to talk aloud during their search, and this information, together with some probing and real time expert interpretation, enabled the experimente to record the searching activity on a highly structured observation form. The study reveals the extent of subject searching activity, and suggests that this may have been underestimated in previous studies. The analysis of expressed topics, search formulation strategy and documents retrieved reveals the adaptive nature of the subject searching process, whereby the user adapts to the structure of the available tools. The information retrieval task in a traditional library system is tailored by the system to a single, one dimensional, sequential process. It is suggested that a major obstacle to subject searching effectiveness may lie in the lack of interaction between the different possible approaches in the searching process: the indexing language, the classification, and the titles. It is to be hoped that a future online searching environment will encourage a more truly interactive approach to subject searching.
