- Abstract
- Points out that designers of information systems for subject retrieval aiming at some kind of uinversal usage face the major problem of context, as a word by itself is not meaningful; and inseparable from this problem is that of the terminology used. This problem is most evident in systems that rely totally on words, rather than a systematic structure of some kind

- Content
- 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.

- Abstract
- Taylor intends this book to be preparatory to traditional texts on cataloging and classification. She reviews why and how recorded information is organized in libraries, archives, museums, and art galleries. She then turns to the methods of retrieving information, such as through bibliographies and catalogs, and methods of encoding information (e.g., MARC and SGML), the metadata related to description and access, subject analysis by means of words, and classification as a further means of subject access. A chapter on systems for information storage and retrieval concludes a book that well fills the need for a single-volume introduction on its subject.
- Content
- "The book should be the natural choice as a textbook for the many new undergraduate courses on organization of information offered by schools of library and /or information science"

- Abstract
- The emergence of information retrieval systems as a means of satisfying information needs has resulted in a large number of theoretical and practical ideas being introduced. These advancements provide the foundation for the theory of IR systems detailed in this book. Attention is also focused on the other areas of information science and how these differing theories interact and rely on each other. The book details algorithms in each process in the system, including those that are radically new in the retrieval process and those that are adaptable to the individual. New apporaches to evaluating information retrieval studying their performance are included
