The Library of Congress Classification (LCC) is a system of library classification that is used to organize and arrange the books and other materials in the collections of the Library of Congress in Washington, D.C. The LCC system is also used by many other libraries in the United States and around the world to classify and organize their collections.
The LCC is a detailed and complex system that divides knowledge into 21 main classes and includes over 200,000 individual subject categories. The main classes are arranged alphabetically and cover a wide range of subjects, including literature, language, history, science, and technology. Within each main class, the individual subject categories are arranged by topic and are assigned a unique classification number.
The LCC system is designed to be flexible and adaptable, and it is regularly updated to reflect changes in knowledge and research. It is used to help librarians and researchers find and access the information they need, and to make it easier for users to browse and discover new materials in the library’s collection.
