Printing |
The following rules govern printing of current, multiple, and former frequency notes: |
| |
- The current and former frequencies (field 310 and
field 321) print as the first note.
- Former frequencies (
field 321) print first in order of their appearance in the record, which should be earliest to most recent.
- Current frequency (field 310) prints following former frequencies.
- Multiple frequency statements print in the order of earliest to most recent.

| AACR2 records |
The print program supplies a comma and a space between multiple frequency statements. The print program also supplies a period at the end of the note unless final punctuation (. ! ?) is present.
