Abstract

Surveys conducted during the last four years under the auspices of the International Federation of Library Associations and Organizations (IFLA) reveal that the Library of Congress Subject Headings is heavily used in national libraries outside of the United States, particularly in English-speaking countries. Many other countries report using a translation or adaptation of LCSH as their principal subject heading language. Magda Heiner-Freiling presents an analysis of the IFLA data, which also includes information on the classification schemes used by the libraries and whether or not the libraries have produced a manual on the creation and application of subject headings. The paper concludes with an Appendix showing the complete data from the 88 national libraries that respond to the surveys

Abstract

Technological developments are introducing both challenges and opportunities for the future production of national bibliographies. There are new complex issues which must be addressed collectively by national bibliographic agencies. As an international community, we must consider new methods and models for the on-going provision of authoritative data in national bibliographies, which continue to play an essential role in the control of and access to each country's published heritage.

Abstract

To assist the IFLA Bibliography Section in gathering more comprehensive information on selection criteria used by national bibliographic agencies in preparing their countries' national bibliography, the Section crafted a survey that the Section chair and the Oslo Programme chair sent electronically and in print form. With the exponential availability of Web and other digital resources, the Section felt a critical need to address how national bibliographic agencies were incorporating these resources into the national bibliography. In preparation for the Section's Programme during the 71st IFLA World Library and Information Congress, the survey was sent to forty-four national libraries and bibliographic agencies in Europe. We restricted dissemination of the survey to European countries, in line with the Section's strategy to plan its programmes in ways that focused on what was happening in the area of the world where the IFLA Congress was being convened. This paper gives an analysis of the data submitted in the responses.

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.
