    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

    Abstract
    The study reported here investigated the query expansion behavior of end-users interacting with a thesaurus-enhanced search system on the Web. Two groups, namely academic staff and postgraduate students, were recruited into this study. Data were collected from 90 searches performed by 30 users using the OVID interface to the CAB abstracts database. Data-gathering techniques included questionnaires, screen capturing software, and interviews. The results presented here relate to issues of search-topic and search-term characteristics, number and types of expanded queries, usefulness of thesaurus terms, and behavioral differences between academic staff and postgraduate students in their interaction. The key conclusions drawn were that (a) academic staff chose more narrow and synonymous terms than did postgraduate students, who generally selected broader and related terms; (b) topic complexity affected users' interaction with the thesaurus in that complex topics required more query expansion and search term selection; (c) users' prior topic-search experience appeared to have a significant effect on their selection and evaluation of thesaurus terms; (d) in 50% of the searches where additional terms were suggested from the thesaurus, users stated that they had not been aware of the terms at the beginning of the search; this observation was particularly noticeable in the case of postgraduate students.

    Abstract
    This experiment explores the effectiveness of retrieving the listing of a known-item book from the 3.6 million entry onine catalog at the library of the University of Michigan using various combinations of author's name plus first and last title words. The principal finding was that 98.9% of the time a 1 to 20 line miniature catalog (minicat) was displayed that contained either the entry sought or a not-in-database (NID) reply when the search comprised all three words.

    Abstract
    In this study descriptions of a novel by 100 users at 2 Swedish public libraries, Malmö and Molndal, Mar-Apr 95, were compared to the index terms used for the novels at these libraries. Describes previous systems for fiction indexing, the 2 libraries, and the users interviewed. Compares the AMP system with their own model. The latter operates with terms under the headings phenomena, frame and author's intention. The similarities between the users' and indexers' descriptions were sufficiently close to make it possible to retrieve fiction in accordance with users' wishes in Molndal, and would have been in Malmö, had more books been indexed with more terms. Sometimes the similarities were close enough for users to retrieve fiction on their own

    Abstract
    The study adopts a naturalistic approach to investigate users' interaction with a browsable MeSH (medical subject headings) display designed to facilitate query construction for the PubMed bibliographic database. The purpose of the study is twofold: first, to test the usefulness of a browsable interface utilizing the principle of faceted classification; and second, to investigate users' preferred query submission methods in different problematic situations. An interface that incorporated multiple query submission methods - the conventional single-line query box as well as methods associated the faceted classification display was constructed. Participants' interactions with the interface were monitored remotely over a period of 10 weeks; information about their problematic situations and information retrieval behaviors were also collected during this time. The traditional controlled experiment was not adequate in answering the author's research questions; hence, the author provides his rationale for a naturalistic approach. The study's findings show that there is indeed a selective compatibility between query submission methods provided by the MeSH display and users' problematic situations. The query submission methods associated with the display were found to be the preferred search tools when users' information needs were vague and the search topics unfamiliar. The findings support the theoretical proposition that users engaging in an information retrieval process with a variety of problematic situations need different approaches. The author argues that rather than treat the information retrieval system as a general purpose tool, more attention should be given to the interaction between the functionality of the tool and the characteristics of users' problematic situations.
