Process of Development of DDC:
The Dewey Decimal Classification (DDC) system, developed by Melvil Dewey in 1876, is one of the most widely used library classification systems in the world. The development of the DDC has evolved over time, and the process involved several key stages:
1. Initial Development (1876): Melvil Dewey, a librarian and educator, created the first edition of the DDC with the goal of organizing library collections in a systematic, easy-to-understand way. The initial classification system was designed to represent knowledge through a decimal system, where each number corresponds to a particular subject. Dewey's main aim was to make knowledge more accessible and to create a universal system for organizing books. The first edition of DDC consisted of 1,000 categories and was focused primarily on the needs of small libraries.
2. Refinement and Expansion (1900-1920s): As libraries grew and new fields of knowledge emerged, Dewey revised and expanded the DDC. The 2nd edition, released in 1894, saw improvements and refinements, particularly in the way new subjects were incorporated. The system became more comprehensive, and new classes were introduced to accommodate emerging fields of study such as psychology and sociology. During this period, DDC was also used internationally, and Dewey adapted it for non-English-speaking countries.
3. Technological Advancements (1930s-1950s): As the world of libraries and information management became more complex, Dewey updated the DDC to incorporate more categories and enhance its functionality. In this era, greater emphasis was placed on standardization and the use of the system in large-scale library environments. This period also saw the publication of the Dewey Decimal Classification Manual, which provided guidance on applying the system in various contexts.
4. Development of Modern Editions (1960s-Present): After Dewey's death, the OCLC (Online Computer Library Center) took over the responsibility for updating and maintaining the DDC. New editions have been published at regular intervals, with the 23rd edition being the most recent, published in 2011. The DDC has continued to evolve, incorporating technological advancements like online catalogs and digital resources. The later editions also focus on making the system more flexible to accommodate interdisciplinary subjects and modern fields of study such as information technology, environmental sciences, and digital media.
5. Global Influence and Adaptation: The DDC system has been adapted for use in libraries worldwide. Different countries and cultures have created variations of the system to suit their linguistic, cultural, and academic contexts. Despite this, the basic structure of the DDC has remained the same, with updates made to reflect the growing body of global knowledge.
In conclusion, the development of the DDC has been a continuous process of refinement, expansion, and adaptation to meet the needs of libraries and users. Dewey’s original vision of creating a universal classification system for libraries has succeeded, and the DDC continues to evolve in response to the changing landscape of knowledge and information.
