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

Keyword and Boolean searching modes are now becoming more commonly available on online public access catalogs, and questions have arisen regarding their use by library patrons. How difficult do users perceive these searches to be? Do those who use them tend to rely on them all the time to the exclusion of all other methods? This study attempts to provide answers to these questions in the context of an academic library that uses the Northwestern Online Total Integrated System Online catalog

Abstract

Briefly reviews research on users and online catalogues, focusing on the different data gathering methodologies. OLIVE, an enhanced facility for logging transactions and introducing online questionnaires as a front end to a personal computer, was used to examine user intentions, search formulations and success ratings on several commercial systems. Describes a third generation system, OKAPI, which addresses some of the issues raised by the user feedback

Abstract

Reports on a study at an elementary school in Washington, DC examining pupils' use of an OPAC. Presents this within the overall instructional environment of the school in order to open a window on the broader interaction of children, technology, curriculum, instruction and learning. Explains the methodology used in the study, the findings of the study, and notes a number of conclusions. Focuses in particular on the patterns of success and failure of children's use of the OPAC, their search strategies and the nature of their interaction with the OPAC

Abstract

An exploratory research study on OPACs was done within the framework of the French PARINFO program by four different teams: ENSSIB-CERSI, City Univ. of London, Médiathèque of the Cité des Sciences et de l'industrie and a firm GSI-ERLI. During the month of June 1992, 650 individual searches on four terminals were collected. The sessions were automatically recorded, accompanied by two online questionnaires, a pre-search and a post-search questionnaire. Some questions were asked orally by an interviewer and the answers noted. The article analyses the researches perceived by user as difficult or impossible. Some examples of the difficulties are given

Abstract

Presents the selected findings of a research project based on the British Library Network Online Public Access Catalogue (NOPAC) carried out in the department of information and library management at the University of Northumbria in Newcastle, UK over the academic year 1994/95. Data was collected by means of interviews with NOPAC users especially on use made of the NOPAC and on attitudes towards the NOPAC's interface. Discusses the views of users as they relate to: display features; mode of interaction; help/user assistance; extra features available; and usability. Lists important points which emerged from the survey concerning the NOPAC service

Abstract

Identifies 6 types of searches on the basis of paudsing behaviour by using cluster analysis. The 6 types of search were highly associated with search fleuncy and the construction of a mental model. Examines learning during multiple searches on the basis of the 6 types. Finds that searchers gain more experience, increase their searching proficiency and become more fluent at searching while online. The changes of search level in multiple searches showed that most searchers moved towards greater fleuncy

Abstract

In order to test the impact of system and domain knowledge on search behaviour in an online catalogue, an experiment was set up in a university library where students from three specialisation areas performed a number of search tasks in the online catalogue. The subjects differed in the amount of domain and system knowledge. In two sessions the subjects performed searches inside and outside their 'own' domain. During the first session, half of the group received instruction in catalogue use and the other half did not. To observe whether the induced differences in system knowledge had effects on the search performance, a second session was carried out. Subjects' search behaviour was videotaped and their comments recorded (They were encouraged to think aloud). Results show that the amount of system knowledge had a significant effect on search time as well as on the number of search patterns observed. regarding domain knowledge, only one out of the six analyses concerning search time or the amount of patterns yielded a significant effect. A possible explanation for this result could be the questionable validity of the criteria used to distinguish between known and unknown domains. The difference in knowledge regarding familiar and unfamiliar domains is not as large as had been expected. The notion of end-users displaying habitual modes of behaviour is given considerable support by the data. This is reflected by the limited number of patterns observed

Abstract

An ongoing thread in information retrieval research has been the exploration of user goals (or information needs, or problems) on information retrieval systems. It has been suggested that an understanding of goals and their role in the information retrieval interaction can provide insight into appropriate retrieval strategies, relevant documents, and general system design. This article reports on empirical findings concerning goals of users searching an OPAC at a northeastern United States university. These findings were generated during a large inductive and qualitative study of users' interactions with the OPAC. It was found that respondents came to the OPAC to search for a variety of course- or degree-related projects in which they were engaged. Respondent goals were not greatly modified during the course of these interactions. A set of situational elements associated with the respondent's goal was also identified. The implications of these findings for OPAC design and the training of informational professionals are discussed

Abstract

Current research on user interfaces to online public access catalogs is reviewed in an attempt to identify research methods and findings applicable to the design of effective user interfaces to online public access catalogs. A broad definition of user interface is employed which includes data structures, in addition to searching and indexing software. The following features of online public access catalogs are discussed: the demonstration of relationships between records, the provision of entry vocabularies, the arrangement of multiple entries on the screen, the provision of access points, the display of single records, and the division of the catalog into separate files or indexes. For each feature, user studies and other research on online public access catalogs are reviewed and those findings summarized which provide insight into user needs concerning that particular feature; issues are identified and directions for further research are suggested. Implications for cataloging codes and standards and system design are discussed
