    Abstract
    The scholarly community is increasingly employing the Web both for publication of scholarly output and for locating and accessing relevant scholarly literature. Organization of this vast body of digital information assumes significance in this context. The sheer volume of digital information to be handled makes traditional indexing and knowledge representation strategies ineffective and impractical. It is, therefore, worth exploring new approaches. An approach being discussed considers the intrinsic semantics of texts of documents. Based on the hypothesis that noun phrases in a text are semantically rich in terms of their ability to represent the subject content of the document, this approach seeks to identify and extract noun phrases instead of single keywords, and use them as descriptors. This paper presents a methodology that has been developed for extracting noun phrases from Portuguese texts. The results of an experiment carried out to test the adequacy of the methodology are also presented.

    Abstract
    Gives operational definitions of work, associated work, composite work and other selected terms. Mentions the challenges posed by the abundant availability of digital resources in different media, forms and formats to catalogers in particular and information professionals in general. Discusses with examples the applicability and adequacy of the rules and prescriptions of ISBD(ER) and AACR2, 1998 rev. for cataloging multimedia resources on CD, in view of the fact that the record medium, the physical form and format affect the effectiveness of accessing, retrieval and use of a work.

    Abstract
    This paper briefly traces the history of library education in India and examines the status of bibliographic organization and control in the country as a major factor influencing the nature and content of courses in knowledge organization. The two basic documents from the University Grants Commission - the first one issued in 1965 and the recent one in 2001 - that have influenced university level course contents have been examined. Finally, the nature of changes that are being brought about in recent years in some universities has been highlighted.
