Library of Congress system

The Library of Congress classification system is a method used by libraries to organize and categorize their books and resources. It assigns a unique code to each item based on its subject area, using a combination of letters and numbers. For example, books on history might start with 'D,' while those on science start with 'Q.' This system helps users and librarians quickly locate materials on specific topics within the library’s collection, making organization efficient and navigation straightforward. It’s widely used by research and academic libraries to systematically arrange vast collections of information.
