24.26. Delegations to International and Intergovernmental Bodies
The first and second examples showing parenthetical additions to the headings are erroneous. Numbers, dates, and locations that apply not to the delegation but to the international undertaking should be expressed at the end of the heading, punctuated with commas and following only the order of elements as prescribed by 24.3A.
When a serial entry is being prepared, follow the usual practice of omitting number, date, and place when appropriate. In monograph cataloging, normally formulate the heading to include number, date, and place (with a separate name authority record in each case).
