Abstract

Reports on the work of the ABDUX project to investigate the use of the standardized protocol for the X.500 directory service for searching distributed bibliographic databases. It is a joint project between the Computer Science Department of the University College London, and the Library and Computer Service of Brunel University, UK. Gives a design overview and discusses the implementation phase of the project which involved: enhancements to an X.500 system; implementing user interfaces; and gathering test data for the system. Examines experiences with the system, and assesses why interest in the system has been less than hoped for. Puts forward a model for bibliographic querying which recognises the role of other protocols. Summarizes the main lessons to be drawn from the project

Abstract

The advent of the multimedia personal computer (MPC) makes available substantial information processing and storage capability that can be accessed relatively easily through a powerful graphical user interface (GUI). The availability of low cost resources such as these now means that new approaches can be used for the development and use of personalized tools for information handling. Discusses the design and implementation of a keyword in context (KWIC) indexing system for use on an MPC and the design of a GUI to support its use

Abstract

Libraries have become an established part of scientific and social cultures and provide an essential mechanism for storing, preserving and sharing documentary records of various types of human endeavour. In recent years, new information handling technologies have emerged and these have significantly influenced the basic nature of conventional paper based libraries and have created a need for new types of 'electronic library'. Discusses some of the changes that have taken place within library systems as a consequence of the emergence of new computerized information handling techniques and presents case studies which outline various developments taking place at the Human-Computer Interaction Laboratory, School of Computing and Mathematics, Teeside University, UK, relating to the creation of electronic books and dynamic electronic libraries, including the Open Access Student Information Service (OASIS)

Abstract

Electronic books have become an important mechanism for the dissemination of large volumes of multimedia and hypermedia information. The utility of books of this sort depends very much upon the use of efficient and effective end user interfaces that embed appropriate book related metaphors. Discusses the use of such metaphors and some experiments aimed at evaluating the uitlity of the book metaphor with respect to reading and referencing tasks. Presents a case study (the Book Emulator) which illustrates how information technology can be used to create online books and lectures for use in university teaching. Concludes with a short discussion of some possible future directions of development of electronic books, that add enhancements to the basic book metaphor and which will enable easier and more widespread access to publications of this sort

Abstract

Describes the work of the ABDUX project, containing a brief description of the rationale for using X.500 for access to bibliographic information. Outlines the project's design work and a demonstration system. Reviews the standards applicable to bibliographic data and library OPACs. Highlights difficulties found when handling bibliographic data in library systems. Discusses the service requirements of OPACs for accessing bibliographic, discussing how X.500 Directory services may be used. Suggests the DIT structures that coulb be used for storing both bibliographic information and descriptions on information resources in general in the directory. Describes the way in which the model of bibliographic data is presented. Outlines the syntax of ASN.1 and how records and fields may be described in terms of X.500 object classes and attribute types. Details the mapping of MARC format into an X.500 compatible form. Provides the schema information for representing research notes and archives, not covered by MARC definitions. Examines the success in implementing the designs and loos ahead to future possibilities
