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

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.
