7. Added entry headings (7XX fields)
a. If an added entry heading is appropriate but the name is not represented in the LC Name Authority file, the RDA form of the name is constructed and used. Give relationship designators as appropriate.
b. An analytical 7XX 12 author-title heading may be provided for all or some of the volumes in a collection of regular monographic material, subject to cataloger's judgment. Obvious name and title access points should be provided for other collections. If considered unusually important, it is possible to give both a controlled access point (7XX 12) and an uncontrolled access point (740 02) for the same title.
c. Within collections there may be occasions when persons or corporate bodies are both an author or issuing body and the subject. Access should be provided through a subject heading (6XX) and a name entry (7XX).
