The LCC system

The Library of Congress Classification (LCC) system is a method used by libraries to organize and categorize books and other materials. It divides knowledge into 21 main classes, each represented by a letter, such as "A" for General Works or "B" for Philosophy. Each class is further divided into subclasses and specific topics, using combinations of letters and numbers. This system helps librarians arrange items systematically and makes it easier for users to locate materials on specific subjects, ensuring efficient research and study.
