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

This entry outlines the history, application, and nature of the Universal Decimal Classification (UDC). It explains its structure, management, revision, and the many changes that have taken place since the Task Force for UDC Development reported in 1990, and the UDC Consortium was formed. This led to the creation of the machine-readable database, or Master Reference File (MRF), consisting of some 66,000 terms, which forms the basis of all published editions and is revised and updated annually. Revision procedures and applications in an online environment are noted and the potential for future development discussed.

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

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
