In cataloging a concordant or other formal agreement between the Holy See and a National government or other political jurisdiction, 21.35C1 provides for an added entry under the heading for the participant not chosen as the main entry heading, with a uniform title added as appropriate under 25.16B1. Because this method provides for the needed access point only when the main entry heading is for the agreement, but not when such an agreement is given as an added or subject entry, the Library of Congress uniformly makes a name/uniform title reference in an authority record for the name/uniform title of the participant chosen as the main entry heading instead of the added entry called for by the rule.
