Definition

The former publication frequency of either an item or an update to an item. Use only when a current publication frequency is given in field 310.
 

If a record has multiple 321 fields, delete them when you add a Frequency varies note.

Use the following guidelines for capitalization, punctuation, and representation of numerals so that the current and former frequencies print correctly:

  • Capitalize the first letter of the first word in subfield ‡a.
  • Enter a comma between subfields ‡a and ‡b.
  • Do not enter final punctuation unless the field ends with an abbreviation.
  • If the first 321 field begins with a number and if field 310 is also present, spell out the number in the first 321 field.
310     4 issues yearly, ‡b Aug 1904-
321     Five issues yearly, ‡b 1901-June 1904
  • Enter each former frequency in a separate 321 field. Enter the former frequencies in the order of earliest to most recent.
  • Spell out a number appearing in the first 321 field only. Use an Arabic numeral in subsequent 321 fields.
