The Dewey Decimal Classification system (DDC) is the world's most popular library classification system. The 23rd edition of the DDC was published in 2011. This second edition of The Theory and Practice of the Dewey Decimal Classification System examines the history, management and technical aspects of the DDC up to its latest edition. The book places emphasis on explaining the structure and number building techniques in the DDC and reviews all aspects of subject analysis and number building by the most recent version of the DDC. A history of, and introduction to, the DDC is followed by subject analysis and locating class numbers, chapters covering use of the tables and subdivisions therein, multiple synthesis, and using the relative index. In the appendix, a number of academically-interesting questions are identified and answered. - Provides a comprehensive chronology of the DDC from its inception in 1876, to the present day - Describes the governance, revision machinery and updating process - Gives a table of all editors of the DDC

A Practical Guide to Dewey Decimal Classification is a hands-on introduction to the world’s most frequently used classification system. The book gives a brief history of the scheme and discusses the theory behind the organization and construction of Dewey class numbers. However, I would like to go further and walk through the process of finding DDC numbers and how to build them using WebDewey, the online resource for accessing DDC. Since DDC is no longer published in print (as of June 2018), it is important that readers understand the basics of using WebDewey. End-of-chapter exercises let readers assess their learning. Chapter coverage is complete: 1. Introduction 2. Dewey Decimal Classification in a Nutshell 3. Basic Principles of Classification (Exercises at the end of the chapter) 4. Searching and Browsing in WebDewey (Exercises at the end of the chapter) 5. Using Notes and the Manual (Exercises at the end of the chapter) 6. Number Building in DDC (Exercises at the end of the chapter) 7. Using Tables within the Schedules (Exercises at the end of the chapter) 8. Advanced Class Number Building Using Table 1 (Exercises at the end of the chapter) 9. Advanced Class Number Building Using Table 2 (Exercises at the end of the chapter) 10. Advanced Class Number Building Using Tables 3-6 (Exercises at the end of the chapter) 11. Conclusion; DDC Resources Appendix: Answers to chapter exercises

Can the Dewey Decimal System meet the needs of the rapidly changing information environment? Moving Beyond the Presentation Layer explores the Dewey Decimal System from a variety of perspectives, each of which peels away a bit of the “presentation layer”—the familiar linear notational sequence-to reveal the content and context offered by the DDS. Library professionals from around the word examine how the content and context offered by the DDS can evolve to meet the needs of the changing information environment, with a special focus on the impact of the Internet on current and future developments. Moving Beyond the Presentation Layer examines whether the Dewey Decimal System is a rigid structure best suited to a physical information environment or a polymorphic one that can be adapted to meet a variety of physical and virtual needs. This unique book reviews the 40-year history of the online use of classification systems, the development of the Relative Index over 22 editions of the DDC, recommendations to ensure the viability of the DDC in a time of mass digitization, using DDS in an environment where it hasn’t been used before, teaching the DDS, special issues related to the use of the DDS in Europe, North America, and Africa, and the future of online classification. Topics examined in Moving Beyond the Presentation Layer include: using the DDC as the browsing mechanism for resource discovery classification as an online cataloging tool classification as an online end-user tool browser behavior in a DDC-based Web service the role of the DDS in the ongoing HILT (High-Level Thesaurus) project using the DDS to organize Web resources localization and interoperability in knowledge organization mapping terminologies to classification systems the DeweyBrowser and much more Moving Beyond the Presentation Layer is an essential professional resource for librarians, information scientists, computer scientists, and metadata and Web services specialists.
