The DDC is built on sound principles that make it ideal as a general knowledge organization tool: meaningful notation in universally recognized Arabic numerals, well- defined categories, well-developed hierarchies, and a rich network of relationships among topics. In the DDC, basic classes are organized by disciplines or fields of study. At the broadest level, the DDC is divided into ten main classes, which together cover the entire world of knowledge. Each main class is further divided into ten divisions, and each division into ten sections. Till now most of the changes involved are only change in Connecting Digit and change in a few Array Isolate Numbers, apart from addition of new facets, extrapolation and interpolation in arrays, and lengthening of chains; these two latter changes do not involve any change in the position of the already existing subjects. The aim of the book is to be amply illustrative and to step by step introduce the concepts and methods.

The Dewey Decimal Classification (DDC) system is a general knowledge organization tool that is continuously revised to keep pace with knowledge. The system was conceived by Melvil Dewey in 1873 and first published in 1876. The DDC is published by OCLC Online Computer Library Center, Inc. OCLC owns all copyright rights in the Dewey Decimal Classification, and licenses the system for a variety of uses. The DDC is the most widely used classification system in the world. Libraries in more than 135 countries use the DDC to organize and provide access to their collections, and DDC numbers are featured in the national bibliographies of more than 60 countries. Libraries of every type apply Dewey numbers on a daily basis and share these numbers through a variety of means. Dewey is also used for other purposes, e.g., as a browsing mechanism for resources on the web. This book is written with complete information on Dewey Decimal Classification and is useful for all the academic librarians and library science students.
