    Abstract
    A browsable display under a specific search term can often frustrate users if the display is carried over several screens. This article investigates methods of compressing headings identified by MARC subfield codes to reduce the size of browsable displays. Arguments are presented that a more efficient system design can be achieved by machine sorting of subdivisions via a conceptual, rather than alphabetical, approach. The author concludes that system architecture for browsable subject index displays must be redesigned to relieve the user of the burden of data organization

    Abstract
    Reports on a dramatic shift from subject to periodical title searching at Colorado University Libraries. States possible reasons for the change, examines problems encountered by users with searching the periodical title index and suggests how this change in online catalogue searching may affect future catalogue design and bibliographic instruction

    Abstract
    OLIVE, a transaction logging facility enhanced with online questionnaires, was used to collect data from users of public and academic library catalogues. The comparative analysis of subject searching behaviour focused on the role of browsing subject headings and brief references in search formulation. Opportunities for browsing are greatly constrained by indexing practices. It is suggested that a more integrated approach to pre-coordinate and post-coordinate searching would be more effective. The logging software has been developed for a number of commercial online catalogues including Geac, CLSI and LIBERTAS. The use of a diagnostic and monitoring tool in the evaluation of OPACs is advocated

    Abstract
    An investigation of tools, techniques, and methods for the evaluation of interactive library catalogues is described, with emphasis on diagnostic methods and on use of the catalogue in a wider context of user information seeking behaviour. A front-end system (Olive) was developed to test verious enhancements of traditional transaction logging as a data-gathering technique for evaluation purposes. These include full-screen logging, pre- and post-search, online/offline, and in-search interactive questionnaires, search replys as well as talk-aloud. The extent of subject or hybrid searching activity as opposed to specific item searching is also highlighted

    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
    This paper describes a survey on how system vendors and libraries handled tagging in OPACs and discovery layers. Tags are user added subject metadata, also called folksonomies. This survey also investigated user behavior when they face the possibility to tag. The findings indicate that legacy/classic systems have no tagging capability. About 47% of the discovery tools provide tagging function. About 49% of the libraries that have a system with tagging capability have turned the tagging function on in their OPACs and discovery tools. Only 40% of the libraries that turned tagging on actually utilized user added subject metadata as access point to collections. Academic library users are less active in tagging than public library users.

    Abstract
    Investigates the reasons for one category of zeor hit author searches - that of plausible but unverifiable names - encountered by end users of the NOTIS OPAC at the University of Illinois at Chicago. The names were not found in the national bibliographic utility (OCLC), the local database (LUIS), the local card catalogue, or large online files of journal articles (Wilson indexes). Concludes that, while the problem of user queries resulting in no retrievals cannot be entirely remedied, a number of things can be done to minimize the problem, including: putting in palce an international system to exchange authority data for names; simplification of cataloguing riles; a retrieval system that allows natural language best match retrieval, ranked output, relevance feedback, and other post Boolean techniques; expanded use of keyword searching; and user education

    Abstract
    This research investigates how people's perceptions of information retrieval (IR) systems, their perceptions of search tasks, and their perceptions of self-efficacy influence the amount of invested mental effort (AIME) they put into using two different IR systems: a Web search engine and a library system. It also explores the impact of mental effort on an end user's search experience. To assess AIME in online searching, two experiments were conducted using these methods: Experiment 1 relied on self-reports and Experiment 2 employed the dual-task technique. In both experiments, data were collected through search transaction logs, a pre-search background questionnaire, a post-search questionnaire and an interview. Important findings are these: (1) subjects invested greater mental effort searching a library system than searching the Web; (2) subjects put little effort into Web searching because of their high sense of self-efficacy in their searching ability and their perception of the easiness of the Web; (3) subjects did not recognize that putting mental effort into searching was something needed to improve the search results; and (4) data collected from multiple sources proved to be effective for assessing mental effort in online searching.
