This system allows each item to be assigned a unique call number. A call number is like an address; it indicates where the item is located on the library shelves.

More about LC Call Numbers

"The Library of Congress Classification (LCC) is a classification system that was first developed in the late nineteenth and early twentieth centuries to organize and arrange the book collections of the Library of Congress. Over the course of the twentieth century, the system was adopted for use by other libraries as well, especially large academic libraries in the United States. It is currently one of the most widely used library classification systems in the world."
