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

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

Digital library research has attracted much attention in the most developed, and in a number of developing, countries. While many digital library research projects are funded by government agencies and national and international bodies, some are run by specific academic and research institutions and libraries, either individually or collaboratively. While some digital library projects, such as the ELINOR project in the UK, the first two phases of the eLib (Electronic Libraries) Programme in the UK, and the first phase of DLI (Digital Library Initiative) in the US, are now over, a number of other projects are currently under way in different parts of the world. Beginning with the definitions and characteristics of digital libraries, as proposed by various researchers, this paper provides brief accounts of some major digital library projects that are currently in progress, or are just completed, in different parts of the world. There follows a review of digital library research under sixteen major headings. Literature for this review has been identified through a search on LISA CD-ROM database, and a Dialog search on library and information science databases, and the resulting output has been supplemented by a scan of the various issues of D-Lib Magazine and Ariadne, and the websites of various organisations and institutions engaged in digital library research. The review indicates that we have learned a lot through digital library research within a short span of time. However, a number of issues are yet to be resolved. The paper ends with an indication of the research issues that need to be addressed and resolved in the near future in order to bring the digital library from the researcher's laboratory to the real life environment.

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
