Although it was developed to organize materials housed at the Library of Congress, the Library of Congress Classification system (LCC) is widely used in academic libraries around the world; it is the primary classification system used by the UCF Libraries. The LCC system begins with 21 categories, each identified by a letter of the alphabet. Most of the categories include subcatagories that are identified by one or two more letters. For example, class N, Art, has subclasses: NA, Architecture; NB, Sculpture, ND, Painting; as well as several other subclasses. Each subclass includes a loosely hierarchical arrangement of the topics pertinent to the subclass, going from the general to the more specific. Individual topics are often broken down by specific places, time periods, or bibliographic forms (such as periodicals, biographies, etc.).
Individual topics are delineated by place, time period, etc. using numbers. For example, ND 673 finds books on painter Peter Paul Rubens (1577-1640). Similarly, E 51-99 finds books about Indians of North America.
Below are the major LCC classes or categories:
