The main collections in the WCSU Libraries are organized using the Library of Congress Classification (LCC) classification system. This system was first developed in the late nineteenth and early twentieth centuries to organize and arrange the book collections of the Library of Congress and was subsequently adopted for use by other libraries, especially large academic libraries.
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. For example, class N, Art, has subclasses NA, Architecture; NB, Sculpture, ND, Painting; as well as several other subclasses, etc.
Other collections in the Libraries use different classification systems, such as the Dewey Decimal Classification used in the Curriculum Collection, and SuDocs Numbers used in the Government Documents Collection.
Parts of the above were adapted from text on the LOC website.
Here is a basic breakdown of the classes:
Please note: Circulating books A-N are on the 4th floor of the Haas Library; P-Z are on the 5th floor.
