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

The Dewey Decimal Classification System, popularly known as DC or DDC, was created by Melvil Dewey more than a century ago. Since then it has gone through constant changes and has grown from a 44 page booklet to four volumes. But its basic plan, notation and desire to serve librarianship has remained stable.

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
