Abstract

The death of Brian Vickery sees a great era of classification research coming towards an end. Born in Australia, he completed his schooling in England, before going up to Brasenose to read Chemistry just before the outbreak of the Second World War. Brian was never in the services, but after Oxford he worked as a chemist in the Royal Ordnance Factory from 1941-45. After the War he became a librarian at Imperial Chemical Industries (ICI). He was a delegate at the Royal Society Scientific Information Conference held in 1948. One of the offshoots of that conference was the formation of a small committee of scientists under the leadership of Professor J.D. Bernal, to make a study of library classification. After two years of discussions, they elicited the assistance of Jack Wells, then editor of the British National Bibliography, and Brian. They circularized a group of colleagues and convened a meeting in February 1952 which led to the formation of the Classification Research Group. As is well known, this Group, all practising librarians, were to exert a groundbreaking influence on the organization and retrieval of information.

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

Abstract

The genesis of the Group: In 1948, as part of the post-war renewal of library services in the United Kingdom, the Royal Society organized a Conference on Scientific Information.' What, at the time, must have seemed a minute part of the grand plan, but was later to have a transforming effect on the theory of knowledge organization throughout the remainder of the century, was the setting up of a standing committee of a small group of specialists to investigate the organization and retrieval of scientific information. In 1950, the secretary of that committee, J.D. Bernal, suggested that it might be appropriate to ask a group of librarians to do a study of the problem. After a couple of years of informal discussion it was agreed, in February 1952, to form a Classification Research Group - the CRG as it has become known to subsequent generations. The Group published a brief corporate statement of its views in the Library Association Record in June 1953 and submitted a memorandum to the Library Association Research Committee in May 1955, entitled "The need for a faceted classification as the basis of all methods of information retrieval". This memorandum was published in the proceedings of what has become known as the "Dorking Conference" in 1957. Of the original fifteen members, four still belong to the Group, three of whom are in regular attendance: Eric Coates, Douglas Foskett and Jack Mills. Brian Vickery ceased attending regularly in the 1960s but has retained his interest in their doings: he was present at the 150th celebratory meeting in 1984 and played an active part in the "Dorking revisited" conference held in 1997. The stated aim of the Group was 'To review the basic principles of bibliographic classification, unhampered by allegiance to any particular published scheme' and it can truly be stated that the work of its members has had a fundamental influence on the teaching and practice of information retrieval. It is paradoxical that this collection of people has exerted such a strong theoretical sway because their aims were from the outset and remain essentially practical. This fact is sometimes overlooked in the literature on knowledge organization: there is a tendency to get carried away, and for researchers of today to concentrate so hard on what might be that they overlook what is needed, useful and practical - the entire objective of any retrieval system.

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.
