    Abstract
    An evidence-based practice approach to search interface design is proposed, with the goal of designing interfaces that adequately support search strategy formulation and reformulation. Relevant findings from studies of information professionals' searching behaviors, end users' searching of bibliographic databases, and search behaviors on the Web are highlighted. Three brief examples are presented to illustrate the ways in which findings from such studies can be used to make decisions about the design of search interfaces. If academic research can be effectively connected with design practice, we can discover which design practices truly are best practices and incorporate them into future search interfaces.

    Abstract
    The HIBROWSE design offers improved searching functionality for users of bibliographic databases. The interface provides a multi windowed view of data stored on a relational database management system, using layered attribute value aggregation and classification. The user interrogates the database by invoking automatically formulated SQL queries that filter the contents of each window according to user selected attribute values. The interface is described using 'hand crafted' screens to create realistic examples of HIBROWSE systems for EPOQUE, INSPEC, MEDLINE and EMBASE

    Abstract
    View based searching and multi view searching using HIBROWSE proposes a new paradigm for information retrieval from bibliographic databases and database management systems. The paradigm replaces command line and form based interaction with query specification and interaction which requires the user to identify views relating to query facets of the subject of their query. Attempted to apply techniques from human-computer interaction design in the development, construction and usability evaluation of a view based searching system for a very large bibliographic database. As the development of the HIBROWSE system had been in progress before usability became a major concern, as well as the class of system being developed, greater progress towards improved usability was made by adopting a less structured development life-cycle. Examined the usefulness of a number of usability evaluation methods in the context of trying to determine the usability of designs in interactive information retrieval systems. Measurement of the subjective usability of prototypes reinforced the finding of users' difficulties in forming a useful account of the system behaviour and functionality from the training material provided, highlighted some aspects of the system that could be improved, and the greater usability of the HIBROWSE prototypes over an extant commercial bibliographic database system

    Abstract
    The searching behaviour of 79 end-users of CD-ROM databases was studied at the UCLA campus libraries. The results indicate that users lack basic knowledge on how to search and consequently their searches are not effective despite their efforts. Users therefore need help through training but most importantly by improving the CD-ROM user interfaces and retrieval systems

    Abstract
    The Online Public Access Catalog (OPAC) is an information retrieval system characterized by short bibliographic records, mainly of books, journals, and audiovisual materials available in a particular library. This, coupled with a Boolean search interface and a heterogeneous user population with diverse needs, presents special problems for subject searching by end users. To perform effective subject searching in the OPAC system requires a wide range of knowledge and skills. Various approaches to improving the OPAC design for subject searching have been proposed and are reviewed in this entry. The trend toward Web-based OPAC interfaces and the developments in Internet and digital library technologies present fresh opportunities for enhancing the effectiveness of the OPAC system for subject searching.

    Abstract
    The behavior of academic library users has drastically changed in recent years. Internet search engines have become the preferred tool over the library online public access catalog (OPAC) for finding information. Libraries are losing ground to online search engines. In this paper, two aspects of OPAC use are studied: (1) the current OPAC interface and searching capabilities, and (2) the OPAC bibliographic display. The purpose of the study is to find answers to the following questions: Why is the current OPAC ineffective? What can libraries and librarians do to deliver an OPAC that is as good as search engines to better serve our users? Revitalizing the library OPAC is one of the pressing issues that has to be accomplished.

    Abstract
    An approach to accessing databases, which makes extensive use of structured thesaurus views for presenting and searching a large bibliographic database through progressive refinement, is being investigated in a research project which is seeking to apply usability criteria as the determinant for interface design. It aims to investigate measurements of retrieval performance in an application of graphical user interface techniques using multi-windowed layered attribute value aggregation, including those provided by a structured thesaurus, to access bibliographic databases. This paper reports on the progress made in the first year of the project of the application of usability methodologies, the revision of a preliminray design and the resulting prototype development. Implications for more widespread applications are discussed

    Abstract
    Demonstrates that a mode of interaction, analogous to the optomechanical principles applied in the Peek-a-Boo system, can be applied in computerized retrieval systems to enhance the quality of human-computer interaction radically and increase effectiveness. The MenUSE (Menu based User Search Engine) software has evolved from constructing explicit Boolean combinations of concepts automatically to using an implicit Boolean searching approach, similar to Peek-a-Boo. Thesauri and classification schemes, together with other searchable values, provide the user with views of a database and a means for the recognition and selection of concepts and other parameters by the end user. The resulting filtering model has been implemented for searching the European Parliament's EPOQUE database and for INSPEC. This second application provides illustrations of the technique for this paper

    Abstract
    The application of classification schemes and thesauri to improve online information retrieval can be traced back to the beginnings of online searching itself, but the true potential for using knowledge structures in the user interface has yet to be realized. View-based searching seeks to exploit the classified arrangements in thesauri and existing classification schemes to improve the performance of such systems. HIBROWSE for EMBASE is a system which demonstrates the power of applying an approach to information retrieval which is strongly related to faceted classification. It does this by employing a point a click user interface with mutually constraining views utilising knowledge structure hierarchies for both query specification and the presentation of results. The relevance of this approach to library OPACs is discussed in the context of the digital library, concluding that out legacy of research in classification and indexing is more relevant than ever in the design of systems to cope with the problems of information access

    Abstract
    Reports progress and future plans for a project to study the interactions of users with information retrieval interfaces. Tests are run with professional data base searchers and with end users who are members of a profession but have little or no searching experience. Interfaces tested include a command language search system used to search DIALOG bibliographic data bases, a non-procedural system that produces DIALOG commands, and several full text systems, including one using hypertext. The intent is to determine which kinds of users perform best with each type of interface. The project is being conducted jointly bay the University of Toronto and the University of Maryland

    Abstract
    In this paper we present the results of an experiment to help professional scientists and engineers undertake their own literature searches using a number of the major online bibliographic databases. The end-users, or experimental subjects, are already familiar with Deco, the text storage and retrieval system used by Unilever, but have little or no knowledge of the major online database systems, such as Orbit, Dialog, BRS, etc. The paper describes the design and development of a front-end system which simplifies the 'logon' procedure and converts Deco format commands into any of the other required languages. The users can thus search any of the major online databases just as if they were searching their own files on their local system ...

    Abstract
    Standards for user interfaces for access to bibliographic data bases cannot be developed without more complete understanding of the current user, user attitude and capabilities. Gives 3 means of achieving this based on observing the user. 45% of access points in subject searches results in no retrievals. Errors in searching on-line catalogues occur with a 40% no hit title search rate and a 51% no hit author search rate when those records were on the data base. Stresses the importance of fundamental user interface components contained in the IBM staff publication systems guide. Concludes that although there is no such thing as a standard user it is still vital to develop user standards
