Abstract

Overview of recent developments in the organization and the policy of the UDC. Description of content and compilation of the Master Reference File, the database of the UDC that will be the starting point for future revision and enhancement of the classification. Some observations are added concerning the direction these developments will take

Abstract

I am pleased to be included as part of this workshop. My contribution comes from my research and working with national bibliographies around the world, not from my expertise with the Dewey Decimal Classification system. With that disclaimer, I am ready to share my observations and experience in how national bibliographies and national bibliographic services use the DDC in national bibliographies, including a case study of the making of the Namibia National Bibliography

This work is a comprehensive guide to Edition 21 of the Dewey Decimal Classification (DDC 21). The previous edition was edited by John Phillip Comaromi, who also was the editor of DDC 20 and thus was able to impart in its pages information about the inner workings of the Decimal Classification Editorial Policy Committee, which guides the Classification's development. The manual begins with a brief history of the development of Dewey Decimal Classification (DDC) up to this edition and its impact internationally. It continues on to a review of the general structure of DDC and the 21st edition in particular, with emphasis on the framework ("Hierarchical Order," "Centered Entries") that aids the classifier in its use. An extensive part of this manual is an in-depth review of how DDC is updated with each edition, such as reductions and expansions, and detailed lists of such changes in each table and class. Each citation of a change indicates the previous location of the topic, usually in parentheses but also in textual explanations ("moved from 248.463"). A brief discussion of the topic moved or added provides substance to what otherwise would be lists of numbers. Where the changes are so dramatic that a new class or division structure has been developed, Comparative and Equivalence Tables are provided in volume 1 of DDC 21 (such as Life sciences in 560-590); any such list in this manual would only be redundant. In these cases, the only references to changes in this work are those topics that were moved from other classes. Besides these citations of changes, each class is introduced with a brief background discussion about its development or structure or both to familiarize the user with it. A new aspect in this edition of the DDC study manual is that it is combined with Marty Bloomberg and Hans Weber's An Introduction to Classification and Number Building in Dewey (Libraries Unlimited, 1976) to provide a complete reference for the application of DDC. Detailed examples of number building for each class will guide the classifier through the process that results in classifications for particular works within that class. In addition, at the end of each chapter, lists of book summaries are given as exercises in number analysis, with Library of Congress-assigned classifications to provide benchmarks. The last chapter covers book, or author, numbers, which-combined with the classification and often the date-provide unique call numbers for circulation and shelf arrangement. Guidelines in the application of Cutter tables and Library of Congress author numbers complete this comprehensive reference to the use of DDC 21. As with all such works, this was a tremendous undertaking, which coincided with the author completing a new edition of Conversion Tables: LC-Dewey, Dewey-LC (Libraries Unlimited, forthcoming). Helping hands are always welcome in our human existence, and this book is no exception. Grateful thanks are extended to Jane Riddle, at the NASA Goddard Space Flight Center Library, and to Darryl Hines, at SANAD Support Technologies, Inc., for their kind assistance in the completion of this study manual.
