Abstract

Survey on the activities going to develop the UDC into a fully faceted classification system according to the Recommendations of the UDC Management Board. A Master Reference File (MRF) has been created from which any publisher or insitution may develop its own versions according to the requests of its clientele. The UDC Technical Director at the FID Headquarters in The Hague maintains the file. An Editorial Board and an Editor in Chief was appointed. Extensions and Corrections are being published. Examples are given on ongoing revision work in the classes for Astronomy, Linguistics and Philology as well as in Medicine. Cooperation with the Editors of the Bliss Classification and the DDC exists

Abstract

Recent developments in the improvement of communication between those responsible for editing the general schemes of classification and their users are outlined. Increased participation in conferences, the publication of guides and manuals for aiding the implementation of general classifications, and the use of the Internet as a means of communicating are all ways in which users hear more about these schemes and can make their views known to those responsible for maintaining them. Increased communication at editorial level, including coordination of current developments and future revisions, is discussed. The Dewey Decimal Classification, the Library of Congress Classification, the Universal Decimal Classification, and the Bliss Bibliographic Classification (BC2) are reviewed and the ways in which each communicates with its users and participates in joint enterprises are noted.

Abstract

After a short presentation of major background principles used in BSO construction, the authors consider the most important structural peculiarities and spheres of application of this system. Some specific remarks deal with subdivisions within several major headings. In general, the BSO is viewed as a reasonable and up-to-date structural outline of modern knowledge and a useful tool to interconnect or switch between information systems

Abstract

4 different items, all of which have direct concern for Africa, have been published between 1991 and 1993 under the auspices of the UDC Consortium, the body now responsible for the maintenance of the UDC. Discusses recent changes in the management structure of UDC. Matters of interest to those concerned with the study of Africa will be found principally in the auxiliary tables, since it is here that most of the detail that is used for specification in the main classes is located. Looks at 2 sections of the classification: tables of language and ethnis subdivisions; and the area table

Abstract

This paper describes a survey of subject analysis research over the ten year period 1988 to 1998. Data are drawn from the 'research environment' encompassing publications, conference papers, major bibliographic resources in the field of Library and Information Science and selective searches of the Internet. Findings reveal major and minor areas of research activity. Trends and developments are identified and conclusions drawn. Strengths and weaknesses in the approaches taken to subject analysis research are discussed and suggestions for improvements are made with a view to future research directions

Abstract

Achieving widespread agreement on subject organization is a complex task, and a challenge greater than that of creating a standard bibliographic description for international exchange-the goal of Universal Bibliographic Control (UBC). This article traces the history of the Universal Decimal Classification (UDC), its relationship with other schemes, and opportunities for further collaboration.

Abstract

Editors of long-standing classifications have to adopt their schemes to totally different circumstances from those they were originally designed to suit. The need to retrieve information accurately in an online environment and a world dominated by the Internet is vital and contrasts with the basic linear approach for which these classifications were intended. The latter need still has to be satisfied, so ways of achieving both goals must be explored. The need for greater synthesis, clearly defined factes, with distinctive notation and a closely adhered to citation order is essential. An expressive notation is attractive in an online environmen. Modern educational approaches make traditional structures meaningless and the current economic climate and expense of developing new publication formats is reducing revision budgets. Co-operation between editors and the use of one scheme, e.g. DDC, as a switching language between other schemes, e.g., UDC, thesauri and subject headings lists are one way forward. Existing co-operative projects and future plans between the editors of DDC, UDC and BC2 are discussed and the complementing of classification by a thesaurus is recommended

Abstract

This book is an extension and total revision of the author's earlier Guide to the use of UDC. The original was written in 1993 and in the intervening years much has happened with the classification. In particular, a much more rigorous approach has been undertaken in revision to ensure that the scheme is able to handle the requirements of a networked world. The book outlines the history and development of the Universal Decimal Classification, provides practical hints on its application and works through all the auxiliary and main tables highlighting aspects that need to be noted in applying the scheme. It also provides guidance on the use of the Master Reference File and discusses the ways in which the classification is used in the 21st century and its suitability as an aid to subject description in tagging metadata and consequently for application on the Internet. It is intended as a source for information about the scheme, for practical usage by classifiers in their daily work and as a guide to the student learning how to apply the classification. It is amply provided with examples to illustrate the many ways in which the scheme can be applied and will be a useful source for a wide range of information workers

Abstract

Prior to the OPAC many institutions devised classifications to suit their special needs. Others expanded or altered general schemes to accommodate specific approaches. A driving force in the creation of these classifications was the Classification Research Group, celebrating its golden jubilee in 2002, whose work created a framework and body of principles that remain valid for the retrieval needs of today. The paper highlights some of these special schemes and highlights the fundamental principles which remain valid. 1. Introduction The distinction between a general and a special classification scheme is made frequently in the textbooks, but is one that it is sometimes difficult to draw. The Library of Congress classification could be described as the special classification par excellence. Normally, however, a special classification is taken to be one that is restricted to a specific subject, and quite often used in one specific context only, either a library or a bibliographic listing or for a specific purpose such as a search engine and it is in this sense that I propose to examine some of these schemes. Today, there is a widespread preference for searching an words as a supplement to the use of a standard system, usually the Dewey Decimal Classification (DDC). This is enhanced by the ability to search documents full-text in a computerized environment, a situation that did not exist 20 or 30 years ago. Today's situation is a great improvement in many ways, but it does depend upon the words used by the author and the searcher corresponding, and often presupposes the use of English. In libraries, the use of co-operative services and precatalogued records already provided with classification data has also spelt the demise of the special scheme. In many instances, the survival of a special classification depends upon its creaior and, with the passage of time, this becomes inevitably more precarious.

Abstract

Outlines the bibliographic enterprise envisaged by Otlet and LaFontaine, which resulted in the UDC being developed in 1895, and the subsequent history of the scheme. Relationship with DDC from which it was derived deteriorated in the early 20th century and changes in funding, location, and editorship of Duyvis from 1929-59 had a profound effect on the scheme's development and management. Lloyd, Duyvis successor, reformed the revision structure, and further management changes from 1975 to the present day, culminated in the formation of the UDC Consortium in 1992. Notes the subsequent creation of a machine-readable Master Reference File and speedier revision procedures. Examines the scheme's structure, development, and influence on classification theory, problems caused by longevity and lack of standrad procedures, and highlights proposals for their reform to improve the scheme's suitability for an automated world. Explores research projects in 1960s which foreshadowed possibilities today, such as a complementary thesaurus and individualisation of single concepts notationally. Emphasizes the value of classification in a multilingual environment and outlines the future developments

1. Introduction The representation of place in classification schemes presents a number of problems. This paper examines some of them and presents different ways in which a solution may be sought. Firstly, what is meant by place? The simple answer is a geographical area, large or small. The reality is not so simple. Place, or Topos to Aristotle was more than just an area, it was a state of mind. But even staying an the less philosophical plane, the way in which a place can be expressed is infinitely variable. Toponymy is a well defined field of study, comparable with taxonomy in the biological sciences. It comprehends the proper name by which any geographical entity is known, and part of the world, feature of earth's surface, organic aggregate (reef, forest) an organizational unit (country, borough, diocese), limits of Earth (poles, hemispheres) parts of Earth (oceans, continents), lakes, mountain passes, capital cities or sea parts.

Abstract

The paper examines the potentiality of the Universal Decimal Classification as a means for retrieving subjects from the World Wide Web. The analytico-synthetic basis of the scheme provides the facility to link concepts at the input or search stage and to isolate concepts via the notation so as to retrieve the separate parts of a compound subject individually if required. Its notation permits hierarchical searching and overrides the shortcomings of natural language. Recent revisions have been constructed with this purpose in mind, the most recent being for Management. The use of the classification embedded in metadata, as in the GERHARD system or as a basis for subject trees is discussed. Its application as a gazetteer is another Web application to which it is put. The range of up to date editions in many languages and the availability of a Web-based version make its use as a switching language increasingly valuable.
