    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
    The degree of variability in the percentage of subject searching in an online public access catalog (OPAC) among branch libraries of one university was studied. A full semester's worth of transactions was analyzed, not sampled. The time units used were hour of the day, day of the week, and week of the semester. The findings show that subject searching varies from a low of 22% to a high of 74% over the hours of a day. Variability for the days of the week ranged from 17% to 64%, and for the weeks of the semester variability ranged from 12% to 70%. Valuable management information on the utilization of the OPAC within each brach library and among all the branch libraries is provided through numerous charts and graphs.

    Abstract
    Menu selection systems reduce training and memorization, simplify entry of choices, and structure the user's task. However, the use of menu selection is no guarantee that novices or experts will be satisfied or able to carry out their work. This article focuses on the multiple design issues in creating successful menu selection systems. These include the primary issue of semantic organization and the host of secondary issues such as response time and display rates, shortcuts for frequent users, titles, phrasing of menu items, graphic layout, and selection mechanisms. Novel approaches such as popup menus and embedded menus are covered. Experimental results and design guidelines are presented

    Abstract
    Canadian library records, bilingual by statute, are created according to a common set of rules and standards. Subject access to the catalogue remains language dependent. Even searches by classification in some OPACs rely first on an alphabetical index as an entering key. Fully bilingual OPACs with authority control and reciprocal references in one file have yet to appear. Thus far the Canadian Workplace Automation Research Center has produced ISIR/SIRI with an online bilingual thesaurus. The National Library of Canada has developed withh DOBIS a bilingual system providing automatic linkages between records and authority files. But true bilingual searching (a search in one language retrieving records in both languages) could be achieved by a built-in automatic translation module. Total accommodation of diacritical marks by terminal keyboards and display monitors is also a challenge to be met.

    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.

    Abstract
    The study assessed the ability of children to categorise concepts that will be used to organise an information retrieval interface. The work was done of Project SEED (Science for Early Educational Development), a project to develop hands-on science programmes for elementary schools. Aims to tailor an interface to the particular skills of children in organising science knowledge. The results are promising for the design of IR interfaces based on children's abilities to manipulate information.
