What classification system is typically used in call numbers?

The classification system typically used in call numbers is the Dewey Decimal Classification (DDC) and the Library of Congress Classification (LCC). Both systems are widely adopted in libraries to organize books and resources effectively, allowing for easier location and access.

The Dewey Decimal Classification is particularly common in public and school libraries, where materials are arranged systematically by subjects, which helps patrons find resources in specific areas of interest. The Library of Congress Classification is more frequently used in academic and research libraries and breaks down subjects into more specific categories, providing a greater level of detail in classification.

By using these systems, libraries can not only maintain an organized collection but also facilitate effective information retrieval for users. Therefore, recognizing that B includes both DDC and LCC reflects an understanding of the duality of classification systems utilized in libraries, enhancing access to a diverse range of information.
