Other materials are classified by applying the Dewey Decimal Classification (21st ed.).

Cataloging facilitates the search and selection of materials stored in the library. Cataloging enables systematic listings of data according to the author's name, title, publication information, published format, and frequency. Such information is organized into a database applying certain formats that allow for a more effective search. The Korean Machine Readable Cataloging (KORMARC) technical rules are applied for cataloging domestic, Asian, and non-print materials. Western volumes are organized by applying the Anglo-American Cataloging Rules 2 (AACR2).
