    Abstract
    Describes the OM Information Service (OMIS), which provides Web access to selected extracts from the writings and sayings of various spirutual leaders, saints, seers, mystics and scholars, with biographical sketches. Web access has been made more interesting through the provision of related images and music, and user and search interfaces have been designed for the novice user. OMIS is ported from a database originally available on CDS/ISIS. Discusses the content and structure of the CDS/ISIS database, requirements for the Web and CD-ROM versions, and system design and implementation for the media. For the CD-ROM, database access is provided using a Windows version of CDS/ISIS operating as a helper application within a Netscape browser

    Abstract
    SALIS is a repository of open source software along with metadata information. It is a pilot project covering the areas of computer networks and information systems. The objective is to demonstrate the usefulness of such repositories to the Indian academic and developer community in making informed decisions while using open source software. To enable organization and retrieval of the information stored in the repository, a modified CCS (Computing Classification Scheme) classification scheme by the ACM (Association of Computing Machinery) was used. Since a sizeable section of the end users community were familiar with the USPTO classification scheme, a need was felt to classify the software by USPTO scheme also. Instead of classifying by two schemes it was decided to have a mapping or a concordance between the two schemes so that the classification process can be simplified. The approach used to derive a concordance between two diverse classification schemes is described.

    Abstract
    Results from research in information retrieval have suggested that significant improvements in retrieval effectiveness can be obtained by combining results from multiple index representioms, query formulations, and search strategies. The inference net model of retrieval, which was designed from this point of view, treats information retrieval as an evidental reasoning process where multiple sources of evidence about document and query content are combined to estimate relevance probabilities. Uses a system based on this model to study the retrieval effectiveness benefits of combining these types of document and query information that are found in typical commercial databases and information services. The results indicate that substantial real benefits are possible

    Abstract
    Discusses various aspects of institutional repositories from the perspective of academic institutions. There is growing interest among individuals and organizations - academic and research organizations in particular - to make innovative use of the digital medium of the Internet and the World Wide Web to reach their constituencies. Researchers and scholars in these are exploring novel ways of disseminating their work, to supplement traditional scholarly communications. The growing number of personal web pages, institutional and organizational websites indicate this trend and the realization by many organizations of the need for developing support systems at the institutional level for capturing, organizing, preserving and disseminating their intellectual output and to leverage on this knowledge capital. Defines institutional repositories, enumerates their features, and discusses their contents, design and development as well as benefits. Open access institutional repositories created and used in institutional environments may have different contents coming from different sources, on different platforms and metadata sets for description, the question of interoperability and enabling ease of access to and use by different categories of users with different information needs, is an important consideration. Several technical and non-technical parameters have a bearing on the success of inter-operable institutional repositories. These include: convincing researchers for content submission and usage of the institutional repositories; defining and managing appropriate content quality; digital rights management (publisher and researcher copyright; and access management); defining and implementing digital preservation strategies; assignment of persistent identifiers to repository items; development of aggregated repository services at consortia/ regional and national level; and development of semantic interoperability schemes. Briefly describes the institutional repositories scenario in India.
