Abstract

Reference services have taken a central place in library and information services. They are also regarded as personalised services since in most cases a personal discussion takes place between a user and a reference librarian. Based on this, the librarian points to the sources that are considered to be most appropriate to meet the specific information need(s) of the user. Since the Web and digital libraries are meant for providing direct access to information sources and services without the intervention of human intermediaries, the pertinent question that appears is whether we need reference services in digital libraries, and, if so, how best to offer such services. Current digital libraries focus more on access to, and retrieval of, digital information, and hardly lay emphasis on the service aspects. This may have been caused by the narrower definitions of digital libraries formulated by digital library researchers. This paper looks at the current state of research in personalised information services in digital libraries. It first analyses some representative definitions of digital libraries in order to establish the need for personalised services. It then provides a brief overview of the various online reference and information services currently available on the Web. The paper also briefly reviews digital library research that specifically focuses on the personalisation of digital libraries and the provision of digital reference and information services. Finally, the paper proposes some new areas of research that may be undertaken to improve the provision of personalised information services in digital libraries.

Abstract

Arguing that environmental sustainability is a growing concern for digital information systems and services, this article proposes a simple method for estimation of the energy and environmental costs of digital libraries and information services. It is shown that several factors contribute to the overall energy and environmental costs of information and communication technology (ICT) in general and digital information systems and services in particular. It is also shown that end-user energy costs play a key role in the overall environmental costs of a digital library or information service. It is argued that appropriate user research, transaction log analysis, user modeling, and better design and delivery of services can significantly reduce the user interaction time, and thus the environmental costs, of digital information systems and services, making them more sustainable.

Abstract

The Internet and related information services attract increasing interest from information retrieval researchers. A survey of recent publications shows that frequent topics are the effectiveness of search engines, information validation and quality, user studies, design of user interfaces, data structures and metadata, classification and vocabulary based aids, and indexing and search agents. Current research in these areas is briefly discussed. The changing balance between CD-ROM sources and traditional online searching is quite important and is noted

Abstract

Design aspects of bibliographic databases are of utmost importance for effective resource sharing and for providing better information retrieval services in libraries. Standard formats such as the Common Communication Format (CCF) may be adapted for the design of databases. Experience shows that some modifications to the CCF format may be more useful for manipulation of data for various libray operations. Proposes the design of a bibliographic database based on CCF for use in Micr-CDS/ISIS. Almost all the mandatory CCF fields have been adopted and a few new fields added for achieving better results. Formats for display of records conform to AACR2. Provides ample catalogue entries and sample indexes to illustrate how the proposed design helps perform various information retrieval operations in libraries. Modifications in the display of records may be achieved with little effort

Abstract: Computerized text retrieval and library management systems have not yet taken a desired shape in Indian libraries, though efforts are being made in this direction. Reviews the current situation in Indian libraries by means of a survey of 10 selected indigenous software packages. Briefly discusses the underlying framework and text retrieval and library management facilities in these packages and concludes that CDS/ISIS along with SANJAY with sonme further modifications, might prove to be the most suitable package for most Indian libraries
