Abstract

Presents a research project funded by the Spanish government and conducted by professors and students of library and information science, principally from the University of Granada, in collaboration with 2 organizations specializing in electronic information. The research group, 'Virtual reality interface for accessing electronic information', aims to define and develop a new interface for access to electronic information, with particular emphasis on the need for a 3-dimensional metaphor designed specially to improve inter-user communication and to facilitate browsing among great volumes of electronic information

Abstract

This paper outlines strategies and methods for tackling the enormous challenges presented by an emerging Information Society in which the resources of libraries and museums are gradually being made available on-line in electronic form. It begins from two fundamental premises: first, that the experience of libraries, museums, archives and similar institutions in organising, ordering, classing and accessing knowledge is an obvious point of departure for serious strategies of search and access. A second premise is that the methods used for presentation of knowledge in libraries offer valuable clues for a coherent access, interface and strategy, offering a key to a common look and feel for all our activities, be it creating, classing, publishing or accessing. Following from these premises is a new approach to the traditions of knowledge collection, organisation and retrieval. At one end of the spectrum there has been a dream that everything could be collected in one centralized institution. This inspired the Library of Alexandria, the British Museum and a host of other efforts. At the other end of the spectrum there has been an assumption that everything could be decentralised in a completely distributed system. Our claim is that neither of these extremes can work, which means that a new model is called for: a centralised repository of meta-data, a digital reference room which is effectively a cumulative collection of all existing reference sections in libraries and museums

Abstract

In the short term, technological advances will not solve the problems of information saturation and electronic gridlock on the Internet. Advocates interface design techniques as the only effective means of addressing the usability problems that frustrate interaction with Internet resources. Collaborative approaches to information retrieval, where search engines are augmented by advice from human experts, can reduce the problems of electronic gridlock and information saturation

Abstract

Explores the hypothesis that using a zooming graphical interface minimizes user disorientation when reading documents in an electronic environment. 36 graduate students at the University of Maryland at College Park, USA, were randomly assigned to read a hypertext document in either Pad++, a zooming graphical interface, or Mosaic, a jump-based interface. Questionnaires, observation, and taped interviews were used to compare and evalutae the use of the 2 interfaces with regard to learning time, performance and user satisfaction. Findings suggest as workstations become more powerful, a hybrid interface that adds continuous zooming to the existing mechanisms of scroll, pan and jump will emerge

Abstract

Outlines the progress of HyperLib, research which began in 1993 to develop a hypertext interface to the online catalogue and other databases at the University of Antwerp. A human factors oriented design methodology was adopted. A user survey was carried out. The project has focused on development of electronic guides and manual and interfaces to access an academic bibliography database and the UDC subject classification scheme. Evaluation is being carried out in 1995

Abstract

User interfaces for CD-ROM products in the academic library environment must accomodate a variety of user and task profiles. Discusses the practical considerations that govern the implementation of interface design principles for such electronic data bases under the following headings: redesign goals; interaction style; menu design and implementation; system structure and the search paradigm; basic system operation and screen layout; simplified features; integrated novice and expert mode; redesign constraints; and hardware and software constraints

Abstract

The physical organisation of items on library shelves using any classification scheme is inevitable a compromise. The best efforts to achieve an arrangement that is helpful to users will be thwarted by the multifaceted nature of these items and the specific needs of the user and the library. Items on a particular subject will be scattered throughout the library building(s) across disciplines, by physical form, by frequency of use and whether and for how long they may be borrowed. Even thought he rich information content of multifaceted items may be represented in the notation, the items required by a user will be scattered across library shelves when the item is placed in a single relative location. This paper explores these issues uisng examples from a University Library classified using the DDC. The electronic context of the library OPAC can transcend the constraints imposed by the predominantly physical nature of library collections, yet the current use of classification schemes in on-line systems retains many of these limitations. Examples of such systems applying DDC on the WWW are discussed and compared with a system that seeks to use DDC in what is called view-based searching. The interface and the resulting browsing and searching capability of a view-based OPAC are described. Ways in which subject access to library collections can be improved and disciplinary scatter resolved by assigning multiple class number to items and exploiting the rich Dewey structure in a faceted form are discussed. It is suggested that the informative power of visual classificatory structures at the search interface will be beneficial to the broader learning experience of the user. The paper concludes that the application of classification schemes in electronic interfaces should not be bound by the the physical constraints that no longer apply in an electronic context but be exploited to provide a complete, flexible and individual interface as determined by the needs of each user

Abstract

Electronic libraries will depend on distributed computing, storage and retrieval standards that enable multiple user interfaces to multiple information stores. Examines the lessons in interface design learned by Carnegie Mellon University Libraries in building their library system. User interface design is difficult and time-consuming. Distributed retrieval has implications for user interface design. User interface design specifications save time and aggravation, user interfaces need to be tested and revised. Politics and egos can disrupt user interface design

Abstract

Browse searching of online catalogs and electronic indexes is a popular means of retrieving information, but some subject heading lists are so extensive that browsing them can be difficult and time-consuming. This resaerch tested one way of presenting a browse interface to reduce the amount of scanning of subject headings required. It found that a hierarchical presentation of headings reduced the amount of scanning required by more than 50% without any reduction in the effectiveness of the search. Better browsable displays of this sort can improve the efficiency of searching but appear not to alter effectivenenss

Abstract

EBSCO Publishing have demonstrated a beta version of EBSCOhost, version 3.0, which includes several new features that enrich searching, enhance result lists and make general navigation into and out of the search interface easier. Features unclude: simultaneous multiple database searching; hierarchical authority files; and additional authority file searching options; including a relevancy ranked 'find more like' feature

Abstract

Suggests techniques and evaluation criteria for information sources and services available on the Internet. The need for qualitative judgements about library materials and information sources is upheld and accepted techniques and evaluation criteria for printed reference works are outlines. The emergence of non-book materials and electronic information formats has created the need for new techniques and criteria relating specifically to online services and CD-ROM products. Use of the Internet by library and information workers is examined, establishing that the majority of current traffic is communications-based. The authors suggest that networked information sources require the development of additional techniques and criteria for evaluation if they are to be used by information professionals. The potential issues in establishing such a list are discussed
