    Abstract
    Discusses the need for facilities for online vocabulary control and standardization of terms, codes, etc., so as to secure consistency in naming of subjects, objects, countries, languages, etc., in databases at data entry stage. Most information storage and retrieval packages for microcomputers including MicroIsis provide for online vocabulary control in formulating search expressions for information retrieval, but not at the data entry stage. VOCON.PAS is a Pascal interface program for use with MicroIsis software for (a) online selection of term(s) and/or code(s) from vocabulary control tool, such as, thesaurus, subject heading list, classification scheme, nomenclature list(s)

    Abstract
    Discusses the issues involved in the development of data formats for computerized information retrieval systems. Integrated databases capable of holding both bibliographic and factual information, in a single database structure, are more convenient for searching and retrieval by end users. Several bibliographic formats have been developed and are used for these bibliographic control puposes. Reviews features of 6 major bibliographic formats: USMARC, UKMARC, UNIMARC, CCF, MIBIS and ABNCD are reviewed. Only 2 formats: CCF and ABNCD are capable of holding both bibliographic and factual information and supporting the design of integrated databases. The comparison suggests that, while CCF makes more detailed provision for bibliographic information, ABNCD makes better provision for factual information such as profiles of institutions, information systems, projects and human experts

    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

    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.
