Case study: Dual headingsCase study:

Dual headings

Dual headings: DefinitionDual headings: Definition

• A heading with two separate terms, the first of which is the main topic and the second of which is the major subordinate topic, e.g., 570 Life sciences Biology

• Main topic and major subordinate topic share the same number and most of the subdivisions

Elimination of dual headingsElimination of dual headings
