Single LC classification number or a number span associated with a 1XX heading in an established heading record or a subdivision record. Source of the classification number is Library of Congress Classification and/or the LC Classification Additions and Changes that are maintained by the Library of Congress. The hyphen (-) between the two class numbers in a range of numbers may be generated based on the presence of both subfields $a and $b.
Classification number(s) may be qualified by a descriptive term when the heading is represented in more than one place in the LC classification schedules. Each classification number or number span associated with a heading is contained in a separate 053 field.
Organizations may conform to Library of Congress practice by applying Subject Cataloging Manual: Classification conventions.
