Structure and Hierarchy of the DDC System
The DDC system organizes knowledge into ten main classes, each subdivided into more specific divisions and sections. This hierarchical structure uses numerical notation to represent subjects, enabling logical categorization and easy retrieval of information.
3;1 Main Classes and Their Significance
The DDC system is structured into ten main classes, each representing a broad subject area. These include General Works, Philosophy, Religion, Social Sciences, Language, Science, Technology, Arts, Literature, and History. Each class provides a foundational framework for organizing knowledge, ensuring a logical and systematic approach to categorizing library materials. This structure simplifies navigation and retrieval of information for users.
3.2 Divisions and Sections Within Each Class
Each main class in the DDC system is further divided into specific divisions and sections, providing a more detailed organization of subjects. For example, the 600 class (Technology) includes divisions like 610 (Medicine) and 620 (Engineering). These subdivisions allow for precise categorization, enabling users to locate specific topics efficiently. This hierarchical structure enhances the system’s functionality and user accessibility.
3.3 Notation and Numbering System
The DDC employs a numerical notation system, using Arabic numbers to represent classes and subdivisions. Numbers are arranged hierarchically, with broader subjects at higher levels and narrower topics at lower levels. For instance, 610 represents Medicine, while 618 specifies Women’s Health. This notation allows for flexible expansion and precise classification, facilitating efficient information retrieval.

Disadvantages and Limitations of the DDC System
The DDC system faces criticism for its complexity in specialized subjects, lack of representation for emerging fields, and cultural bias, limiting its adaptability for diverse collections.
5.1 Complexity in Certain Subject Areas
The DDC system can be overly complex for specialized or interdisciplinary subjects, such as emerging technologies or niche fields. Its reliance on decimal expansions often leads to lengthy, cumbersome numbers. Additionally, the lack of clear guidelines for certain modern topics creates confusion, making classification and retrieval challenging for both librarians and users. This complexity limits its effectiveness in dynamic, evolving knowledge domains.
5.2 Lack of Representation for Emerging Fields
The DDC system often struggles to accommodate emerging fields like artificial intelligence, digital media, and advanced technologies. These subjects frequently lack specific classifications, forcing librarians to use broader categories. This limitation can lead to inconsistent organization and make it difficult for users to locate materials on cutting-edge topics. The system’s slower update cycle exacerbates this issue, leaving modern subjects underrepresented.
5.3 Cultural and Language Bias
The DDC system reflects a Western bias, favoring English-speaking cultures and potentially marginalizing non-Western perspectives. This can result in inadequate representation of diverse cultural contexts and languages. While efforts have been made to address these issues, the system’s historical roots in Western knowledge organization continue to present challenges for global inclusivity and equitable representation of all cultures.
