    Abstract
    This article examines searcher behavior and affective response to a hypertext-based bibliographic information retrieval system called HyperLynx for searchers with different search skills and backgrounds. Search times and number of nodes visited were recorded for five specified search queries, and views of the system were recorded for each searcher. No significant differences were found in search times or user satisfaction with the system, indicating that a hypertext-based approach to bibliographic retrieval could be appropriate for a variety of searcher experience levels

    Abstract
    Part of a special issue on hypertext and information retrieval. Conventional information retrieval systems provide little support for browsing. Browsing is the major method of searching in hypertext system but users can become disoriented even when browsing small information space. If hypertext is to be used to support browsing in bibliographic databases navigational assistance will be required. Examines the role of thesauri as navigational aids for subject domains of Bibliographic databases. Presents the design of an experimental hypertext-based browsing inference for a thesaurus and its implementation using a commercially available hypertext program. Examines strategies for linking the thesaurus to a database

    Abstract
    Reports on research examining the relationship of searcher performance and perception of performance, particulary for hypertext-based onformation retrieval systems for bibliographic data. Employs a prototype hypertext bibliographic retrieval system called HyperLynx. Evaluates its use by 83 subjects at the School of Library and Information Science and the Golda Meir Library at the University of Wisconsin-Milwaukee, USA. Measures of system usgae indicate that there is no significant relationship between confidence and the number of record pages visited, although confident searchers searched for shorter time periods. The reality check measures shows that both novice and experienced searchers were over confident in their performance

    Abstract
    Examnies several feasibility issues and initial design considerations for a hypertext system for structured bibliographic retrieval. HyperLynx was developed using Asymmetric Toolbox. By combining searchable term indexes and inter-record linkages between common authors and descriptors, a flexible search environment is established conductive to browsing

    Abstract
    Presents a state of the art review of the application oh hypertext searching techniques to online catalogues. The technique improves traditional online catalogues: when consulting the catalogue in a non linear way; and when browsing bibliographic information. New research could improve access to larger databases including thesauri and classification schemes

    Abstract
    Investigates how linkage environments in a hypertext based bibliographic retrieval system affect retrieval performance for novice and experienced searchers, 2 systems, 1 with inter record linkages to authors and descriptors and 1 that also included title and abstract keywords, were tested. No significant differences in retrieval performance and system usage were found for most search tests. The enhanced system did provide better performance where title and abstract keywords provided the most direct access to relevant records. The findings have implications for the design of bilbiographic information retrieval systems using hypertext linkages

    Abstract
    Explores inter record linkage relationships of a bibliographic hypertext system through the use of descriptor term co-occurrences. Using term distribution and term exhaustivity data for an existing system, develops 3 models of term co-occurrence and tests against the observed data. The developed models do not adequately model the observed co-occurrence patterns for select parts of the distribution using chi-square values. With knowledge of the structure of such a hypertext system, an appropriate model may be constructed and used as the basis for studying systems design of inter-record linkages and system navigation by users in such a hypertext system

    Abstract
    Describes a study which investigated the affective response of 83 subjects to 2 versions of a hypertext-based bibliographic retrieval system. The objective of the study was to determine if subjects preferred searching a hypertext information retrieval (IR) system via traditional bibliographic links or via an enhanced set of linkages between structured records. The study also examined the utility of using factor analysis to explore subjects' affective responses to searching the 2 hypertext-based IR systems; explored the effect of experience on search outcome; and compared the effect of different types of linkages within the hypertext system. Findings reveal a complex relationship between system and user that is sometimes contradictory. Searchers found the systems to be usable or unusable in different ways indicating that further researchg is needed to isolate to specific features that searchers find frustrating or not in searching structured records via a hypertext-based IR system

    Abstract
    Hypertext for multi-media and full-text documents is rapidly developed on all fronts. For bibliographic information retrieval the applications are promising but pose several difficulties. Describes work conducted at the School of Library and Information Science at Univ. of Western Ontario the objective of which is to add the capability of a browsing search to an existing OPAC through the use of Windowed Hypertext Interface for Zippy Retrieval and Display (WHIZRD) software. Discusses the underlying retrieval capabilities of the system. Examines design problems and solutions and outlines future enhancements

    Abstract
    Describes a hypertext-based system that integrates the bibliographic information of the library catalogue with user-defined knowledge structures, imports information at the user's command, and offers a dynamic personal information tool for active users. Describes the structure and the content of the data base, and shows how the system can be accommodated to different user groups or individual users.
