Decimal classification definitions

Understanding Decimal Classification

Decimal classification is a system used to organize and categorize information in libraries. It was first developed by Melvil Dewey in 1876 and is based on grouping subjects into 10 main classes, each of which is further divided into 10 divisions, and then into 10 sections. This hierarchical system allows for a precise and efficient way of classifying a wide range of subjects.

How Decimal Classification Works

The decimal classification system assigns a unique number to each subject based on its main class, division, and section. For example, if a book falls under the subject of biology, it might be classified under the main class of Science, division of Life Sciences, and section of Biology. The number assigned reflects the specific subject matter of the book, making it easier for library users to locate and retrieve relevant materials.

The Benefits of Decimal Classification

One of the main advantages of decimal classification is its universal applicability. Libraries around the world use the Dewey Decimal Classification system, making it easier for researchers, students, and academics to access information regardless of their location. Additionally, the hierarchical nature of the system allows for a high level of specificity, enabling users to narrow down their search to find exactly what they are looking for.

Challenges of Decimal Classification

Despite its benefits, decimal classification also has its limitations. One of the main challenges is that it can be rigid and may not always align with the fluid nature of knowledge and information. As new subjects emerge or existing ones evolve, the system may struggle to accommodate these changes effectively. Additionally, some critics argue that the system can be Eurocentric and may not adequately represent diverse perspectives and knowledge systems.

The Future of Decimal Classification

While decimal classification has been a staple in library organization for over a century, its future remains uncertain. With the rise of digital libraries and new technologies, alternative classification systems and metadata standards are being developed to meet the changing needs of users. However, the core principles of decimal classification – organization, accessibility, and specificity – continue to influence modern information organization practices, ensuring its legacy in the digital age.
