The Library of Congress Classification (LCC) is a system used to organize and categorize books and other materials in libraries. Developed by the Library of Congress, it assigns unique alphanumeric codes to subjects, making it easier for users to find related items. For example, books about history might start with the letter "C," while those on literature begin with "P." This classification system helps libraries manage their collections efficiently. By grouping similar topics together, patrons can easily browse and discover new materials. The LCC is widely adopted in academic and research libraries, ensuring a consistent approach to organizing knowledge across institutions.
