1.3 Brief History of DDC Development
The Dewey Decimal Classification (DDC) was first introduced in 1876 by Melvil Dewey as a 42-page pamphlet titled A Classification and Subject Index for Cataloguing and Arranging the Books and Pamphlets of a Library. This marked the beginning of modern library classification. The system has since evolved, with the 19th edition being the most recent. The DDC is now maintained by the Library of Congress, ensuring its relevance and adaptability to changing knowledge systems. Its development has been instrumental in standardizing library organization globally.
Structure of the DDC System
The DDC system organizes knowledge into 10 main classes, each subdivided into further categories using decimal notation, creating a hierarchical and detailed classification structure for library materials.
2.1 Main Classes and Their Significance
The DDC system is built around 10 main classes, ranging from 000 (General works) to 900 (History and geography). Each class represents a broad subject area, providing a logical framework for organizing knowledge. These classes are further divided into subclasses, allowing for precise categorization of library materials. The main classes are essential as they form the foundation of the DDC system, enabling libraries to systematically arrange collections and facilitate easy access for users. This hierarchical structure ensures consistency and clarity in classification, making it a cornerstone of library organization worldwide.
2.2 Subdivisions and Hierarchical Organization
The DDC system employs subdivisions to further refine subjects within each class. These subdivisions include form (e.g., dictionaries, fiction), language, and geographic or chronological aspects. The hierarchical structure allows for precise categorization, starting with broad main classes and narrowing down to specific topics. This organization ensures that materials are logically grouped, making it easier for users to locate related resources. The use of subdivisions enhances the system’s flexibility and adaptability, enabling libraries to tailor classifications to their unique collections and user needs while maintaining overall consistency.
2.3 Role of the Decimal Notation System
The decimal notation system is the backbone of the DDC, enabling precise and flexible classification. Each number represents a specific subject, with decimals allowing for further subdivision. This hierarchical structure ensures that related topics are grouped together, facilitating easy navigation. The decimal system also accommodates new subjects by adding more digits, making it scalable. Its standardized format ensures consistency across libraries worldwide, aiding in resource discovery and maintaining order in collections. This notation is integral to the DDC’s effectiveness in organizing knowledge and supporting library operations globally.
