Definition

 The current publication frequency of a continuing resource (serial or integrating resource). Previous OCLC practice was to omit field 310 if the frequency was adequately described in Freq and Regl. Current practice is to enter the current known frequency in field 310.

See Freq (Frequency) and Regl (Regularity) and field 321 (Former Publication Frequency) for more information.

  • 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 field begins with a number and does not have field 321, spell out the number.
    310 Seven issues yearly, ‡ b Jan. 1986-
    [No field 321 is used.]
  • If the record has a 310 field and one or more 321 fields, use Arabic numerals in field 310 and spell out the number in the first field 321.

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.

310 Monthly, ‡ b 1949-1956
321 Five issues yearly, ‡ b 1947
321 14 issues yearly, ‡ b 1948
Prints as:
Five issues yearly (1947), 14 issues yearly (1948), Monthly, (1949-1956).

The print program supplies parentheses around the dates in subfield ‡b of fields 310 and 321. If the final character in subfield ‡ b is a hyphen, the print program supplies three spaces before the closing parenthesis.

Freq: m
Regl: r
310 Monthly, ‡ b 1968-
Prints as:
Monthly, (1968- ).

Pre-AACR2 records

 

The print program supplies a semicolon 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.

310 5 no. a year ‡ b 1945-48
321 Four no a year, ‡ b 1931-44
Prints as:
Four no a year, 1931-44; 5 no. a year, 1945-48.

Records with no 310 fields

 

If a record has no 310 field, the print program supplies a frequency note based on the Freq code. See Freq (Frequency) for more information.
