Abstract

More and more libraries are providing access to Web resources through OCLC's (Online Computer Resource Center) Cooperative Online Resource Catalog (CORC) and, by extension, OCLC's WorldCat database. The ability to use a database to its maximum potential depends upon understanding what a database contains and the guidelines for its construction. This study examines the characteristics of Web resources in CORC in terms of their subject matter, the source of the content, publication patterns, and the units of information chosen for representation in the database. The majority of the 414 resources in the sample belonged to the social sciences. Academic libraries and government agencies contributed more than 90% of the records for resources in the sample. Using the Anglo-American Cataloguing Rules, 2d edition (AACR2) definitions for publication patterns that are part of the upcoming 2002 amendments reveals that nearly half of the sample fell into the category of integrating resources. Identifying units of representation of the resources described was more difficult. Existing definitions for Web units in development are not adequate to describe all of the resources in the sample. In addition, there is wide variability in the units of representation chosen for inclusion by the libraries contributing records, resulting in little predictability in what units of information might be found in the database.

Abstract

This article describes the Online Computer Library Center's (OCLC) Open WorldCat program. WorldCat is a worldwide union catalog created and maintained collectively by more than 9,000 member institutions. Open WorldCat seeks to make library collections and services visible and available through popular search engines such as Yahoo! and Google and other heavily used sites on the open Web. In this capacity, Open WorldCat provides an important central connection between the shared information of the library network and the Web. The article describes the history and rationale of the project; explains how Open WorldCat works for information seekers, participating libraries, and partners; and reports on what OCLC has learned from the program to date.

Abstract

Subject classifications and thesauri have become more important than ever in the Web environment. Efforts made to organize information into subject classifications, or taxonomies, offer users the opportunity to substantially improve the effectiveness of their search and retrieval activities. This article continues earlier research an the development of a new definition of the field of information science and the creation of a "map" of the field showing subjects central to it and their relationships to those an the periphery. A case study describes the creation of a new classification structure (taxonomy) for the Information Science Abstracts (ISA) database, aiming to reflect and accommodate the rapid and continued technological and market changes affecting the information industry today and into the future. Based an a sample of some 3,000 ISA abstracts, two validation experiments were conducted by a three-member team comprising a database editor, a reference librarian, and an abstractor-indexer, who represent three of the major communities within the information science field. In the first experiment, the sample of abstracts was classified according to the proposed new taxonomy; alter analysis of the data and revision of the taxonomy, it was revalidated and fine tuned in a second experiment. Indexer consistency measures obtained in this study were significantly higher than those found in previous studies. The taxonomy resulting from this research employs the concepts, definition, and map of information science previously developed. It presents them in an organized hierarchical view of the field and thus makes a significant contribution to information science.

Abstract

The successful development of computer technology for automating Chinese, Japanese, and Korean (CIK) vernacular scripts and the completion of the RLIN CJK system in 1983 marked the beginning of online operations of East Asian libraries in North America and helped keep them in the mainstream of library automation. The RLIN CJK system and the subsequently developed OCLC CJK system are building CJK bibliographic databases which have made East Asian cooperative cataloging and resources sharing a true reality. The emergence, features, current conditions, and future plans of the two CJK systems are discussed. So are the automated programs of national libraries in East Asia in terms of their building national databases for vernacular materials and designing and producing national MARCs for exchange of bibliographic information among libraries. The outlook of cooperation between the CJK systems and international exchange of CJK bibliographic information is also examined.

Abstract

The 1991 IFLA programme given by the section on bibliography presented the theme that national bibliography becomes part of national memeory by recording the publications of the nation. Examines whether the widely distributed publications of popular culture are 'forgotten' by national bibliography. Considers the bibliographic control of newspapers, mass market publications and erotica in the US bibliographic control system. For the last 2 categories, searches selected titles in the OCLC database where many publications were found with wide distribution but recorded by few or no libraries. Popular culture materials should be recorded in national bibliographies to provide a more extended and historically accurate national memory

Abstract

A bibliography is traditionally characterized by the judgments, bounded by explicit selection criteria, made by a single compiler. Because these criteria concern the attributes ascribed to a work and the needs of readers, bibliographic work is largely conceptual even across technological eras and domains. Yet, the development of networked information services, made possible by WWW infrastructure, has enabled very large numbers of people to discover, organize, and publish information, including bibliographies. Indeed, bibliographies, or at least bibliography-like artifacts, are a common genre of website, often published by people without specialized skills in information organization who follow non-rigorous selection procedures. Nevertheless, even if the items from these lists are poorly selected and described, this publishing activity is fundamentally important because it structures information locally, creating a patchy network of secondary access points. In turn, these access points enable information discovery, the formation and development of communities of interest, the estimation of document relevance by search engines, and so on. In sum, this activity, and the enabling technical infrastructure, invites bibliographies to take on new interactive possibilities. The aim of this article is to extend the traditional view of bibliography to encompass collaborative possibilities for wide, or narrow, participation in the shaping of bibliographies and the selection of items. This is done by examining the nature of bibliography on the Web, by proposing a conceptual model that opens bibliography to participatory practices, and by discussing a case study where a team sought to develop a bibliography of electronic resources. This examination reveals splendid opportunities for expanding the notion of bibliography with participatory policies while remaining true to its ancient roots.

Abstract

This article presents examples of metadata collaborations between the Swiss National Library (NL) and research institutions in the field of Swiss historiography. The NL publishes the Bibliography on Swiss History (BSH). In order to meet the demands of its research community, the NL has improved the accessibility and interoperability of the BSH database. Moreover, the BSH takes part in metadata projects such as Metagrid, a web service linking different historical databases. Other metadata collaborations with partners in the historical field such as the Law Sources Foundation (LSF) will position the BSH as an indispensable literature hub for publications on Swiss history.

Abstract

The DanBib system is a nation-wide union catalogue offering a number of common functions and a network to all Danish libraries - public as well as academic ones. The system is managed by the Danish Library Centre Ltd - a privately organized company owned by national and local government together with the biggest Danish publishing house. The Danish way is, indeed, unique in an international context. In this article a number of basic prerequisites which had to be fulfilled to bring about the Danish solution are discussed.

Abstract

The Working group on Guidelines for (electronic) national bibliographies was established in 2004 has started the work with an analysis of users and contexts of use of national bibliographies (NB) in the digital age. National bibliographies are changing dramatically: they include more and more also bibliographic records for digital resources and national bibliographic agencies are increasingly complementing (or even replacing) printed versions of NB with electronic. The guidelines will be soon posted for the world-wide review; this paper gives and overview of the document prepared so far.

Abstract

The database of the Research Libraries Group's Research Libraries Information Network contains some 25 million records in all USMARC formats for bibliographic and authorities data, as well as a number of additional files for specialized data. These records include source data from the Library of Congress and other national bibliographic agencies, and records contributed by RLG member institutions, and are used both for technical processing and in support of RLG's cooperative programs. Chinese, Japanese, Korean and Cyrillic vernacular records are included in the central database; work on Hebrew is in progress. Future developments will result in the addition of diverse kinds of data, including nonbibliographic data, to RLIN.

Abstract

Effective resourcesharing presupposes an infrastructure which permits users to locate materials of interest in both print and electronic formats. 2 approaches for providing this are union catalogues and Z39.50 based distributed search systems and computer to computer information retrieval protocols. The advantages and limitations of each approach are considered, paying particular attention to a relaistic assessment of Z39.50 implementations. Argues that the union catalogue is far from obsolete and the 2 approaches should be considered complementary rather than competitive. Technologies to create links between the bibliographic apparatus of catalogues and abstracting and indexing databases and primary content in electronic form, such as the new Serial Item and Contribution Identifier (SICI) standard are also discussed as key elements in the infrastructure to support resource sharing

Abstract

In non-English-speaking countries the measurement of research output in the social sciences and humanities (SSH) using standard bibliographic databases suffers from a major drawback: the underrepresentation of articles published in local, non-English, journals. Using papers indexed (1) in a local database of periodicals (Érudit) and (2) in the Web of Science, assigned to the population of university professors in the province of Québec, this paper quantifies, for individual researchers and departments, the importance of papers published in local journals. It also analyzes differences across disciplines and between French-speaking and English-speaking universities. The results show that, while the addition of papers published in local journals to bibliometric measures has little effect when all disciplines are considered and for anglophone universities, it increases the output of researchers from francophone universities in the social sciences and humanities by almost a third. It also shows that there is very little relation, at the level of individual researchers or departments, between the output indexed in the Web of Science and the output retrieved from the Érudit database; a clear demonstration that the Web of Science cannot be used as a proxy for the "overall" production of SSH researchers in Québec. The paper concludes with a discussion on these disciplinary and language differences, as well as on their implications for rankings of universities.

Abstract

Discusses the frustrations and challenges of compiling bibliographies that include WWW references. Search and retrieval skills acquired using older online sources are not always transferable to the Web, and evaluation and authentication of resources remain poor. Cited references frequently disappear, leading to complaints from bibliography users. The Web has also changed many users' perceptions of what they should get from other information providers, increasing their expectations and demands, particularly for the more frequent updating of bibliographies. Suggests a partnership approach can help, where users feed back information about the availability of resources they are seeking; this can have many benefits for both parties

Abstract

As part of a largerstudy concerning the scatter of library and information science (LIS) documents in bibliographic databases, this paper focuses on the publishing sources of a sample of 822 highly relevant documents. 67% were journal articles with the largest subject categories outside of LIS being medicine / health sciences, business, education, and computer science. Other journal titles ranged from popular and trade magazines to scholarly journals spanning the disciplinary map. The largest number of nonjournal items were conference reports, government reports, bibliographic resource guides, monographs, and nongovernment agency reports. These were scattered mostly between technological and medical databases. The results show that LIS is an interdisciplinary field, borrowing and supplying information to and from other disciplines. Articles written about the application of LIS concepts to other fields are often published in the journals of those other fields, not in LIS journals
