Library Classification Systems
There are many ways to organize library collections. Dewey Decimal Classification (DDC) has traditionally been used in public libraries, and Library of Congress (LC) has been used by university and research libraries. There is also Superintendent of Documents classification (SuDoc) and UN classification. For more information about these code-based systems, click here.
Many libraries are moving to intuitive, kid-friendly, word-based organization systems, such as ShelfLogic, Metis and BISAC. BPL has adopted a hybrid classification system, using intuitive categories to group books while retaining Dewey Decimal/author’s last name classification within those categories.
