LCC is influenced by which classification system?

The Library of Congress Classification (LCC) system was developed by the Library of Congress in the United States and is not directly based on any other classification system. However, it was influenced by the Dewey Decimal Classification (DDC) system, which was developed by Melvil Dewey in the late 19th century and is widely used in libraries around the world. Like the DDC, the LCC system is a system for organizing and classifying library materials in a way that makes it easy for patrons to find what they are looking for. However, the LCC system is more detailed and specific than the DDC, and is tailored specifically to the needs of the Library of Congress.
