What classification system does the Library of Congress use?

The Library of Congress uses a hierarchical classification system, which organizes materials into a structured framework that reflects the relationships among various subjects. This system, known as the Library of Congress Classification (LCC), allows for a comprehensive categorization of a wide range of topics, enabling users to locate materials on similar subjects easily.

In the LCC, categories are labeled with letters followed by numbers, indicating broad subject areas and their subdivisions. This structure is particularly helpful for research and academic purposes, as it provides both a systematic and logical way to arrange books and other resources based on subject matter.

Understanding the correct classification system helps in recognizing how libraries organize their collections, making it easier for librarians and patrons to find and categorize information.
