Use rules 23–29 to decide the access
points (name headings and/or titles) that are to be added to the
bibliographic description (see rules 0–11) so that the
description can be added to, and retrieved from, a catalogue.
Use rules 23–28 to decide which access
point is the heading for the main entry (other access points being
headings for added entries). If, however, your library does not
distinguish between main entries and added entries, treat all access
points as equal and use rules 23–29 to tell you which and how
many access points to make.
Generally, each rule and its example(s) only
cover certain added–entry access points. Additional
added–entry access points (for example, series and title
headings) may be required by the general rule on added entries (see
rule
29).
