    Abstract
    Reports on the results of a transaction analysis and user survey, evaluating a pilot system for computerized community information in a public library, based on the GDIS system (Gemeenschaps Informatie Documentair System). The non hierarchical and global approach to the integrated database proved to be useful for novice users. Out of many parameters only frequency of use correlates with retrieval success. The online questionnaire proved to be worthwhile although restricted in scope. The logbook transaction analysis yielded a rich amount of useful management information for the systems managers. The user survey yielded a rich set of data on which to perform statistical analyses according to social science practice, from which some interesting relations could be detected

    Abstract
    This article characterises the questioning behaviour in reference interviews preceding delegated online searches of bibliographic databases and relates it to questioning behaviour in other types of interviews/settings. With one exception, the unit of analysis is the question (N=610), not the interview. The author uses A.C. Graesser's typology of questions to analyse type of question and M.D. White's typology of information categories to determine the question's content objective; this is the first application of Graesser's typology to interview questions in any setting. Graesser's categories allow for a more subtle understanding of the kind of information need underlying a question. Comparisons are made between questions asked by the information specialist and those asked by the client. Findings show that the information specialist dominates the interview, about half the questions were verification questions and about 22% were judgemental questions or requests; all but four types of questions from Graesser's categories appeared in the interviews, but no new question types were discovered. Clients often phrase questions as requests. In content, both clients and information specialists focus on the subject and service requested, but the clients ask also about search strategy and output features. Both parties ask predominantly short-answer questions. Results are related to interface design for retrieval systems.

    Abstract
    Almost 30 years ago, Taylor (1968) postulated that each information need moves along a continuum from the visceral need through the compromised need. The current study examines the final transition in this continuum: from formalized need (expressed in an explicit verbal statement) to compromised need (represented in the language of the retrieval system). This transition is primarily concerned with vocabulary: the searcher attempts to translate an explicit statement of need into a search term (or terms) that can be interpreted by the retrieval system. A few studies have empirically examined the match between the end-user searcher's formalized need and the compromised need (i.e., search terms). Markey (1984) compared the searcher's expressed topic (the formalized need, expressed in just a few words) and the search terms (the compromised need), and then went on to compare the search terms with the library catalog terms available for subject searching. She found that the search term matched or was a partial form of the expressed topic in 71% of the searches, and that over 75% of these searches matched a catalog term. Allen (1991) examined the relationship between logical reasoning ability and selection of search terms. He asked college students to read a magazine article (which could be seen as a very rich statement of the formalized need) and then to perform a search for articles on the same topic (expressing the compromised need).

    Abstract
    This paper highlights some of the significant findings from author's PhD: "Factors affecting the end-use of electronic databases in public libraries." Public libraries have a wide range of different types of users who, unlike academic or special library users, are not necessarily information-trained (see Coles, 1998). Whereas the academic, special library user may have specific information needs that can be met by electronic sources, public library users do not necessarily have such specific information needs that can easily be identified and met. Most user surveys have tended to concentrate on the searching and retrieval aspect of information seeking behaviour, whereas this study's user survey focused more on how people perceived and related to Information and Communication Technologies (ICTs). It was not how people searched a particular electronic source, in this case CD-ROM, that was of prime interest but rather whether or not people actually used them at all and the reasons why people did or did not use electronic media. There were several reasons the study looked at CD-ROM specifically. Firstly, CD-ROM is a well established technology, most people should be familiar with CD-ROM/multimedia. Secondly, CD-ROM was, at the start of the study, the only open access electronic media widely available in public libraries. As well as examining why public library users chose to use electronic sources, the paper looks at the types of CD-ROM databases used both in the library and in general Also examined are what sort of searches users carried out. Where appropriate some of the problems inherent in studying end-users in public libraries and the difficulty in getting reliable data, are discussed. Several methods were used to collect the data. I wished to avoid limiting research to a small sample of library sites, the aim was to be as broad in scope as possible. There were two main groups of people 1 wished to look at: non-users as well as CD-ROM users
