DDC stands for Dewey Decimal Classification, which is a system used to organize and classify library materials. Developed by Melvil Dewey in 1876, the DDC is one of the most widely used library classification schemes. It provides a systematic arrangement of books, journals, audiovisual materials, and other resources based on their subject matter.
The concept behind the DDC is to assign a unique number to each subject area, allowing libraries to categorize their collections in an organized and consistent manner. The classification system is hierarchical, with broad subjects divided into narrower subcategories. Each level of classification is represented by a three-digit number, and further subdivisions are denoted by additional digits.
The DDC is based on the principle of organizing knowledge into ten basic classes, which cover various fields such as philosophy, social sciences, natural sciences, and the arts. These ten main classes are further divided into more specific areas, facilitating the location and retrieval of materials within a library.
The DDC has been adapted and expanded over the years to accommodate new subjects and disciplines, ensuring its continued relevance and applicability in modern library settings. It provides a valuable tool for library professionals and users in effectively organizing and accessing information resources in an efficient and consistent manner.
