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.

Abstract

Subject searching is difficult with traditional text-based online public access library catalogues (OPACs), and the next-generation discovery layers are keyword searching and result filtering tools that offer little support for subject browsing. Next-generation OPACs ignore the rich network of relations offered by controlled subject vocabulary, which can facilitate subject browsing. A new generation of OPACs could leverage existing information-organization investments and offer online searchers a novel browsing and searching environment. This is a case study of the design and development of a virtual reality subject browsing and information retrieval tool. The functional prototype shows that the Library of Congress subject headings (LCSH) can be shaped into a useful and usable tree structure serving as a visual metaphor that contains a real world collection from the domain of science and engineering. Formative tests show that users can effectively browse the LCSH tree and carve it up based on their keyword search queries. This study uses a complex information-organization structure as a defining characteristic of an OPAC that goes beyond the standard keyword search model, toward the cutting edge of online search tools.

Abstract

For users, the catalogue is a tool to assist in satisfying information demands. Bibliographic databases raise the question of how to describe a document to facilitate retrieval. Information technology development have led to the creation of hypercatalogues, affording links to related material and other services. This necessitates improved descriptive cataloguing and also improved search interfaces to simplify user manipulation, along the lines of the Web. Given the massive output of electronic documents, the librarian's role is to select, prioritise and organise. The information society and its consequent economic consequences for the social organisation of knowledge raise the prospect of marginalisation of libraries. Catalogues enable access to knowledge as a public good, but this access must be democratic

Abstract

Preparing for new cataloging such as metadata beyond MARC and thesauri beyond LCSH, is an exciting and daunting challenge for university libraries. Advancing technologies, as well as a growing demand for quality information with rapid access is fueling the need for technical services departments to restructure their work to accommodate the evolving world of information management. Catalogers who have been following the same procedures and practices for many years may find this change particularly difficult. Team leaders are often faced with breaking through skepticism and resistance to this new work in order to enable necessary progress. We found that discussions and gradual introduction of new directions is important to acceptance by team members. However, just as important is the implementation of an action plan to ensure that progress is ongoing. Reengineering Acquisitions and Cataloging into Current Processes and Information Management Initiatives, along with forming several focus groups to investigate and evaluate cataloging work, is proving successful for embracing new cataloging at Tufts University.

Abstract

Libraries pay considerable attention to the creation, preservation, and transformation of descriptive metadata in both MARC and non-MARC formats. Little evidence suggests that they devote as much time, energy, and financial resources to the ongoing maintenance of non-MARC metadata, especially with regard to updating and editing existing descriptive content, as they do to maintenance of such information in the MARC-based online public access catalog. In this paper, the authors introduce a model, derived loosely from J. A. Zachman's framework for information systems architecture, with which libraries can identify and inventory components of catalog or metadata maintenance and plan interdepartmental, even interinstitutional, workflows. The model draws on the notion that the expertise and skills that have long been the hallmark for the maintenance of libraries' catalog data can and should be parlayed towards metadata maintenance in a broader set of information delivery systems.

Abstract

Preparing for new cataloging such as metadata beyond MARC and thesauri beyond LCSH, is an exciting and daunting challenge for university libraries. Advancing technologies, as well as a growing demand for quality information with rapid access is fueling the need for technical services departments to restructure their work to accommodate the evolving world of information management. Catalogers who have been following the same procedures and practices for many years may find this change particularly difficult. Team leaders are often faced with breaking through skepticism and resistance to this new work in order to enable necessary progress. We found that discussions and gradual introduction of new directions is important to acceptance by team members. However, just as important is the implementation of an action plan to ensure that progress is ongoing. Reengineering Acquisitions and Cataloging into Current Processes and Information Management Initiatives, along with forming several focus groups to investigate and evaluate cataloging work, is proving successful for embracing new cataloging at Tufts University.

Abstract

The information in a manual card catalogue cannot be transformed into a machine-readable file without some cleanup work. Correcting problem records only as they are reported by patrons or discovered by staff, in the course of normal workflow, can mean that incomplete, incorrect or obsolete information is left in the database for long periods of time. A large database editing project, while it requires a major investment of staff time, can clean up the online file and improve patron access in a relatively short time. Suggests a method which focuses on specific types of catalogue records in the library's online system. Such a database editing project represents an investment in the future that more than justifies the time and effort that go into it

Abstract

Digital documents and Internet access are changing cataloguing practices. MARC formats can accomodate Internet documents by assigning a field for URL but quality control is vital, especially with multimedia catalogues, and new links have to be created. Heterogeneous distant resources can now be searches using the Z39.50 standard, thus enabling access to a wide range of diverse catalogues, and Internet formats are being used to create local systems (intranets). The librarian needs new skills to manipulate digital documents and use information technology tool but the mission is the same: to optimise access to the widest possible range of information

Abstract

With the ever-increasing developments in information technology and networks, end users of the online environment now have integrated access to a variety of bibliographic databases, mainly library catalogues and A&I services, from a single terminal. While such a facility influences users' expectations and preferences in the searching, retrieval and presentation of bibliographic information, it raises an important question as to whether different bibliographic practices can use a similar or compatible set of principles for creating bibliographic records and files. This paper is an attempt to identify areas of possible reconciliation and also address some of the implications of such an issue.
