- Abstract
- Reports results of a study of the use of metaphors as problem solving mechanisms by novice searchers of bibliographic databases. Metaphors provide a framework or 'familiar structure' of credible associations within which relationships in other domains may be considered. 28 students taking an undergraduate course in information retrieval at Sydney University of Technology, were recorded as they 'talked through' a search on a bibliographic retrieval system. The transcripts were analyzed using conventional methods and the NUDIST software package for qualitative research. A range of metaphors was apparent from the language use by students in the search process. Those which predominated were: a journey; human interaction; a building or matching process; a problem solving process, and a search for a quantity. Many of the studentes experiencing the interaction as a problem solving process or a search for quantity perceived the outcomes as successful. Concludes that when memory for operating methods and procedures is incomplete an unconscious approach through the use of a conceptual system which is consonant with the task at hand may also lead to success in bibliographic searching

- Abstract
- Part of a larger study which aims to: empirically investigate book-index usage, behaviours, and the extent to which specific print index features affect a user's search for information; and to examine these features in an electronic environment and to determine the optimum specifications for indexes in electronic texts by gathering evidence from a controlled user study. Provides an overview of the research project, focusing on a subset of the results from the study of hard-copy book indexes. Describes observable behaviours of a sample of users when consulting different variations of a hard copy book index. Suggests a preliminary model at 3 levels of abstraction repressing users' behaviours when using a book index

- Abstract
- User persistence in displaying postings is a significant human factor in the design of computer driven information systems, including online catalogs. Expert opinion and a study of users of a first generation online catalogue have suggested that users normally display no more than 30 to 35 postings. A follow up study on a second generation system with a larger database found that a greater proportion of users reported overload, but 100 postings (rather than 15) were considered 'too many'. Partially persistent users typically displayed 28 postings, but overloaded uses did not outnumber totally persistent users until postings retrieved exceeded 200. The findings suggest that, given sufficient resources, designers should still consider 30 to 35 postings typical persistence, but also justify treating 100 or 200 postings as a common threshold of overload

- Abstract
- This article reprots the findings of an experiment employing a simulated scholarly use of an OPAC to determine the frequency of one-screen displays when a scholar searches for a known-item with so-called 'keywords' in an implied boolean system. The experiment revealed that a 'keyword' search formula comprising surname plus first and last title words produced a single screen 92.8% of the time, thereby reducing the failure of traditional title searching to produce single screens by nearly one half; such a formula also enables a scholar to search successfully with abbreviated, unsearchable bibliographic citations. Additional research should be carried out, for if it is further demonstrated that replacing traditional bibliographic catalog entries with transcribed title pages provides an improved known-item OPAC, users would benefit and libraries would enjoy huge savings

- Abstract
- Reports on part of a study of real users' behaviour in selecting documents from a list of citations resulting from a search of an information retrieval system. Document selection involves value judgements and decision making. Understanding how users evaluate documents and make decisions provides a basis for designing intelligent information retrieval system that can do a better job of predicting usefulness

- Abstract
- The Web provides a massive knowledge source, as do intranets and other electronic document collections. However, much of that knowledge is encoded implicitly and cannot be applied directly without processing into some more appropriate structures. Searching, browsing, question answering, for example, could all benefit from domain-specific knowledge contained in the documents, and in applications such as simple search we do not actually need very "deep" knowledge structures such as ontologies, but we can get a long way with a model of the domain that consists of term hierarchies. We combine domain knowledge automatically acquired by exploiting the documents' markup structure with knowledge extracted an the fly to assist a user with ad hoc search requests. Such a search system can suggest query modification options derived from the actual data and thus guide a user through the space of documents. This article gives a detailed account of a task-based evaluation that compares a search system that uses the outlined domain knowledge with a standard search system. We found that users do use the query modification suggestions proposed by the system. The main conclusion we can draw from this evaluation, however, is that users prefer a system that can suggest query modifications over a standard search engine, which simply presents a ranked list of documents. Most interestingly, we observe this user preference despite the fact that the baseline system even performs slightly better under certain criteria.

- Abstract
- Reports results of a study which applied a typological procedure, developed by Lazairsfeld from the social sciences, to a set of qualitative data on fiction reading habits for the purpose of forming a practical typology of fiction borrowers. The data was collected from a sample of 300 readers in 2 medium sized UK public libraries over a 2 month period. The procedure, using an inductive research approach, first mapped readers along 6 dimensions of reading habits which emerged from the data frequencies of borrowing, the numbers of authors currently read, the literary/recreational orientation of reading, searching approaches usually applied, sureness (confidence) in book selection and then proceeded to reduce the number of combinations formed by these dimensions, based on their relationships. A typology of 7 types of fiction borrowers was devised: readers of particularism; readers of frequent literary pluralism; readers of infrequent literary pluralism; readers of frequent recreational pluralism; readers of infrequent recreational pluralism; readers of frequent universalism; and readers of infrequent universalism
