A2. Added entries at the third level of cataloging (Appendix A - Part I)
At this level, the selection of individuals and corporate bodies who receive added entries and the number of name, subject, and genre added entries also depend on the type of material being cataloged. More in-depth access can be provided by making substantially more added entries for personal names, corporate bodies, and subject headings.

A2.1. Personal name and corporate body added entry headings
