The University of Kentucky Libraries uses the Library of Congress Classification System (LCC) to assign call numbers to most print materials--books, periodicals, and music scores.
LCC call numbers can tell you a lot about a book or score before you even find it on the shelf.
This page shows you how to read a call number, lists call number ranges for music materials, and how to find materials on subjects outside music.
The Library of Congress Classification System is divided into large subject areas which are called "classes." All classes--and subclasses--begin with one, two, or three letters followed by a number which represents more specific aspects of a subject.
Below is an outline of the major classes:
The Library of Congress Classification System (LCC) 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.
The system divides all knowledge into twenty-one basic classes, each identified by a single letter of the alphabet. Most of these alphabetical classes are further divided into more specific subclasses, identified by two-letter, or occasionally three-letter, combinations.
Below is an outline showing the main classes in LCC:
