"Wer wissenschaftliche Informationen und Fachliteratur sucht, kommt mit einer herkömmlichen Internet-Suchmaschine nicht weit. Auch Bibliothekskataloge und Datenbanken helfen nur begrenzt weiter, da es zu viele Anlaufstellen im Web gibt. Das Hochschulbibliothekszentrum NRW (hbz) arbeitet deshalb an der technischen Infrastrukturlösung eines gemeinsamen Suchraums. Der Suchraum fasst mithilfe modernster Suchmaschinentechnologie viele unterschiedliche Datenquellen zu einem optimierten Index zusammen, der von verschiedenen Suchanwendungen in Sekundenschnelle abgefragt werden kann. Zu den Datenbeständen des Suchraums gehören die Kataloge der deutschsprachigen Bibliotheken sowie Artikel aus den Wissenschaftszeitschriften. Hinzu kommen Abstracts, Inhaltsverzeichnisse und andere Informationen. Ergänzt wird dieser Suchindex durch einen Zugriff auf Fachdatenbanken, die zum Beispiel das vascodaProjekt zusammenträgt. Die Suchanwendungen wie beispielsweise die Portal-Lösung »DigiBib - Die Digitale Bibliothek« müssen nur noch den einheitlich aufgebauten Index durchsuchen und erhalten die Ergebnisse nach wenigen Millisekunden. In der Realität existiert eine solche virtuelle Metabibliothek nur in den Anfängen. Der Dreiländerkatalog des hbz und das Wissenschaftsportal vascoda sind ein großer Schritt auf dem Weg zu diesem gemeinsamen Suchraum. Er kann nur durch eine - inhaltlich und geografisch-weiträumige Kooperation der Universitäten, Bibliotheken, Verlage und anderer Anbieter von Fachinformationen der deutschsprachigen Länder aufgebaut werden. Die Grundlagen für dieses Ziel wurden bereits vom hbz gelegt. Die Teilnahme am Suchraum ist eine lohnende Aufgabe für die Bibliotheken und Wissenschaftsorganisationen: Am Ende steht eine wissenschaftliche Suchmaschine, die alle wichtigen und nützlichen Datenquellen erfasst."

Abstract

Examines the future of the cataloguer in an increasingly electronic environment arguing that this future will depend on adopting a more holistic approach that broadens the concept from cataloguing to the organization of information. If the goal of libraries is to provide access to information it is the organizational tools created by cataloguers that help meet this goal. Cataloguers must be aware of the potential uses of information and how it may be exploited and administrators must capitalize on cataloguers' expertise when information systems based on their work are developed

Abstract

The catalogue as we know it today is the result of a long process of evolution, which began over 250 years ago. At that time, the catalogue served as an index to all materials within a library's collections. However, the tremendous growth in the amount of information produced and the proliferation of formats for that information have forced the catalogue to compromise its indexing function for virtually all formats except monographs. This trend has resulted in a de-emphasis of the catalogue as a tool for retrieving information. Fortunately, the technology of the online catalogue makes possible the reintegration of other information sources into the catalogue. Discusses the decline of the catalogue and proposes some areas in which it may be improved for the next century.

Abstract

Library information searching lacks a descriptive theory which explains how a user decides to borrow one book and not another. Such theory should act as a reference framework against which cataloguing rules and the classification system can be measured, and should be based on 2 complementary perspectives, described in detail: modern classification theory, which explains what cataloguing and classification involve, and philosophy of science, which explains what happens when the user meets the catalogue record. Catalogue information must answer which work is described, and why this work on the subject is chosen. A descriptive theory is especially necessary for knowing what new information to add to the catalogue. Discusses this in a subsequent article

Abstract

Presents a brief reexamniation of the views expressed in the essay mentioned. That essay suggested that scholars, in particular, would have difficulty dealing with the mass of information available in the catalogues of the future and offered several suggestions for lessening their burdens. While those suggestion have not been adopted, it appears as though the mass of information now available from all sources, including library catalogues is far greater than anticipated. Offers further speculations about how libraries might best be involved in organizing access to information in the future

Abstract

The quality of large catalogs is uneven and often low, but this issue is underrated and understudied. Library catalogs often fail to communicate correct and clear information to users and their low quality is not simply due to faults, duplications, and so on but also to unwise cataloging standards and policies. While there is plenty of uncontrolled information about books and other publications, the need for good-quality bibliographic information is apparent and library catalogs may provide a trustworthy map of the publishing output, with full control of editions, works, authors, and so on and effective navigation functions, which are lacking in today's information-rich environment.

Abstract

Extensive literatures exist on information searching theory and techniques, as well as on the Bradford Distribution. This distribution, also known as "Bradford's Law of Scattering," tells us that information on a subject is dispersed in a characteristic and robust pattern that appears consistently across many different environments. This pattern may be expected to have important implications for information searching theory and techniques. Yet these two research literatures are rarely considered in relation to each other. It is the purpose of this article to distinguish three Bradford regions and speculate on the optimum searching techniques for each region. In the process, browsing, directed searching in databases, and the pursuit of various forms of links will all be considered. Implications of growth in size of a literature for optimal information organization and searching will also be addressed.

Abstract

Many small libraries do not have the resources to build a holdings database but the availability of affordable scanners and improved OCR software has made possible a new approach for creating online databases. Describes the work undertaken at the Otto Hahn Library of the Max Planck Institute for Biophysical Chemistry, Germany, to create a database consisting of the titles, bibliographic descriptions and contents tables of books acquired by the library. The book information and table of contents pages are scanned and converted to text using OCR software. A computer program is used to extract as much information as possible, in particular from the CIP data with corrections and missing information being supplied manually. Finally, the information, which consists of: title; author; ISBN; publication year; call number; series; language; and other relevant information for books, as well as the entire table of contents, is stored and added to an Ovid database using the Ovid Local Loader software. Pays particular attention to the algorithm used to extract specific information from the CIP data. 2 OCR software packeges have been tested: OmniPage Pro 7.0 and FineReader 3.0. Experience has shown that FineReader is better at character recognition and retains the formatting better but OmniPage Pro is easier to train to recognize special characters

Abstract

What kinds of mental models do library catalogue users have of the bibliographic universe in an age of online and electronic information? Using phenomenography and grounded analysis, it identifies participants' understanding, experience, and conceptualisation of the bibliographic universe, and identifies their expectations when using library catalogues. It contrasts participants' mental models with existing LIS models, and explores the nature of the bibliographic universe. The bibliographic universe can be considered to be a social object that exists because it is inscribed in catalogue records, cataloguing codes, bibliographies, and other bibliographic tools. It is a socially constituted phenomenon.

Abstract

In pt.1, argued that modern classification theory and philosophy of science can help us understand problems of searching. In pt.2, discusses the problems in a more technical sense. considers thesauri and studies of of concept formation: choice of subject headings; definitions, and associations between subject headings; and the librarian as intermediary between the users and the library's texts. Tests the hypothesis that a catalogue record can be improved by adding information which makes the record more precise. If a record clearly indicates that a book is a typical or non-typical book on a subject, no improvement is necessary. discusses how and what new information to add and psychological barriers to this

Abstract

Works are key entities in the universe of recorded knowledge. Works are those deliberate creations (known variously as opera, oeuvres, Werke, etc.) that constitute individual sets of created conceptions that stand as the formal records of knowledge. In the information retrieval domain, the work as opposed to the document, has only recently received focused attention. In this paper, the definition of the work as an entity for information retrieval is examined. A taxonomic definition (that is, a definition built around a taxonomy) is presented. An epistemological perspective aids in understanding the components of the taxonomic definition. Works, thus defined as entities for information retrieval, are seen to constitute sets of varying instantiations of abstract creations. These variant instantiations must be explicitly identified in future systems for documentary information retrieval. An expanded perception of works, such as that presented in this paper, helps us understand the variety of ways in which mechanisms for their control and retrieval might better be shaped in future.

Abstract

This paper reviews the enormous changes in cataloging and classification reflected in the literature of 2003 and 2004, and discusses major themes and issues. Traditional cataloging and classification tools have been re-vamped and new resources have emerged. Most notable themes are: the continuing influence of the Functional Requirements for Bibliographic Control (FRBR); the struggle to understand the ever-broadening concept of an "information entity"; steady developments in metadata-encoding standards; and the globalization of information systems, including multilinguistic challenges.

Abstract

Information seeking is a fundamental human activity. In the modern world, it is frequently conducted through interactions with search systems. The retrieval and comprehension of information returned by these systems is a key part of decision making and action in a broad range of settings. Advances in data availability coupled with new interaction paradigms, and mobile and cloud computing capabilities, have created a broad range of new opportunities for information access and use. In this comprehensive book for professionals, researchers, and students involved in search system design and evaluation, search expert Ryen White discusses how search systems can capitalize on new capabilities and how next-generation systems must support higher order search activities such as task completion, learning, and decision making. He outlines the implications of these changes for the evolution of search evaluation, as well as challenges that extend beyond search systems in areas such as privacy and societal benefit.
