Abstract

Today many libraries are using computers and allied information technologies to improve their work methods and services. Consequently, the libraries need such professional staff, or need to train the present one, who could face the challenges placed by the introduction of these technologies in the libraries. To meet the demand of such professional staff, the departments of Library and Information Science in India introduced new courses of studies to expose their students in the use and application of computers and other allied technologies. Some courses introduced are: Computer Application in Libraries; Systems Analysis and Design Technique; Design and Development of Computer-based Library Information Systems; Database Organisation and Design; Library Networking; Use and Application of Communication Technology, and so forth. It is felt that the computer and information technologies biased courses need to be restructured, revised, and more harmoniously blended with the traditional main stream courses of library and information science discipline. We must alter the strategy of teaching library techniques, such as classification, cataloguing, and library procedures, and the techniques of designing computer-based library information systems and services. The use and application of these techniques get interwoven when we shift from a manually operated library system's environment to computer-based library system's environment. As such, it becomes necessary that we must follow an integrative approach, when we teach these techniques to the students of library and information science or train library staff in the use and application of these techniques to design, develop and implement computer-based library information systems and services. In the following sections of this paper, we shall outline the likeness or correspondence between certain concepts and techniques formed by computer specialist and the one developed by the librarians, in their respective domains. We make use of these techniques (i.e. the techniques of both the domains) in the design and implementation of computer-based library information systems and services. As such, it is essential that lessons of study concerning the exposition of these supplementary and complementary techniques must be integrated.

Abstract

Will there be a library catalogue in the future and, if so, what will it look like? In the last 25 years, the library catalogue has undergone an evolution, from card catalogues to OPACs, discovery systems and even linked data applications making library bibliographic data accessible on the web. At the same time, users expectations of what catalogues will be able to offer in the way of discovery have never been higher. This groundbreaking edited collection brings together some of the foremost international cataloguing practitioners and thought leaders, including Lorcan Dempsey, Emmanuelle Bermès, Marshall Breeding and Karen Calhoun, to provide an overview of the current state of the art of the library catalogue and look ahead to see what the library catalogue might become. Practical projects and cutting edge concepts are showcased in discussions of linked data and the Semantic Web, user expectations and needs, bibliographic control, the FRBRization of the catalogue, innovations in search and retrieval, next-generation discovery products and mobile catalogues.

Abstract

"Big Data" is on the covers of Science, Nature, the Economist, and Wired magazines, on the front pages of the Wall Street Journal and the New York Times. But despite the media hyperbole, as Christine Borgman points out in this examination of data and scholarly research, having the right data is usually better than having more data; little data can be just as valuable as big data. In many cases, there are no data -- because relevant data don't exist, cannot be found, or are not available. Moreover, data sharing is difficult, incentives to do so are minimal, and data practices vary widely across disciplines. Borgman, an often-cited authority on scholarly communication, argues that data have no value or meaning in isolation; they exist within a knowledge infrastructure -- an ecology of people, practices, technologies, institutions, material objects, and relationships. After laying out the premises of her investigation -- six "provocations" meant to inspire discussion about the uses of data in scholarship -- Borgman offers case studies of data practices in the sciences, the social sciences, and the humanities, and then considers the implications of her findings for scholarly practice and research policy. To manage and exploit data over the long term, Borgman argues, requires massive investment in knowledge infrastructures; at stake is the future of scholarship.

Abstract

Throughout most of human history, people got the information they needed for their lives more or less automatically and unthinkingly--through people they talked with, and from their own life experiences. Today, we are inundated with information but often know little about how to find our way through the vast sea of recorded knowledge to get to what we really want and need. In the information sciences researchers have thought a great deal about information seeking, and have studied people in the grip of trying to satisfy an information need. Much has been learned about how to enable comfortable and fun information searching in human, paper, and digital environments. Professor Marcia Bates of UCLA's Department of Information Studies has collected fifteen of her major papers on information searching in theory and practice in this volume. The articles address many aspects of searching for information, including searching tactics and techniques, the "vocabulary problem" in online searching, the kinds of indexing terms to use in various contexts, the Bradford Distribution and its effects on searching in large databases, the true nature of browsing, and how to design computer interfaces for successful searching. For all the variety in types of information systems, the human being interacting with an information source is remarkably stable in psychology and behavior. These human traits and system features are explored in depth in this book. Bates' popular articles, "What is Browsing--Really?" and "The Design of Browsing and Berrypicking Techniques for the Online Search Interface," are included. This is Volume II of three containing selected works by Bates. The others are titled: Information and the Information Professions (Vol. I) and Information Users and Information System Design (Vol. III)

Abstract

L'examen des titres communs nous a montré qu'en tous les cas, une partie des titres pertinents échapperaient à une requête effectuée par l'intermédiaire du lien. Il nous semble donc plus important que les efforts se concentrent sur les moyens d'effectivement donner un accès à des documents potentiellement pertinents plutôt que de définir plus précisément la qualité des liens au vu des résultats. Une première voie est le recours aux relations hiérarchiques des langages documentaires, mais nous avons vu qu'elles ne sont pas en mesure d'apporter une solution dans tous les cas. Le recours à une classification, à une ontologie ou à des techniques de traitement automatique du langage sont d'autres voies à explorer, qui peuvent éviter de devoir multiplier les liens, et par là compliquer encore leur gestion. En chemin, nous avons rencontré , mais sans pouvoir les aborder, encore bien d'autres questions, qui sont toutes autant de défis supplémentaires à relever, comme le problème de l'accès aux titres non indexés ou le problème de l'évolution des langages documentaires et donc de la mise à jour des liens. Nous avons aussi laissé de côté les questions techniques de l'accès de l'interface aux différents catalogues et des possibilités de présentations des résultats de recherche proprement dits (par bibliothèque interrogée ou réunis en un ensemble, ranking). Il reste ainsi assez à faire jusqu'au jour où un usager pourra entrer un terme de recherche dans une interface conviviale, qui lui ouvrira un accès thématique simple mais complet aux ressources des bibliothèques d'Europe, puis du monde !
