The Dewey Decimal Classification (DDC) is a general knowledge organisation 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 the most widely used classification system in the world. Libraries in more than 135 countries use the DDC to organise and provide access to their collections.
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. The system has value because of its well-defined categories, well-developed hierarchies, rich network of relationships among topics, worldwide use, and language-independent representation of concepts.
The present book aims to provide the concepts and methods of DDC in a lucid way. It highlights special features of the successive editions of DDC. The content of the book will be highly beneficial to students, teachers and professionals in the field of library and information science.
