NOTE:  See MARC 21 Format for Bibliographic Data (830 Series Added Entry - Uniform Title) for code definitions not given below.


Field 830 contains added entries for series entered under title or uniform title.  For serials cataloged according to AACR2, this field is the most commonly used series added entry field.

CONSER standard record (CSR) cataloging practice:

It is not required to search the Library of Congress/NACO Authority File (LC/NAF) for series authority records, or to create or update series authority records for a series statement being recorded in field 490 0#.

A series statement (490 0#) is required when a formal series added entry (8XX) is not included in the bibliographic record.

It is not required to record a series statement in field 490 or 5XX when a series added entry (8XX) is included in the bibliographic record even when the established form of the series heading differs from the series statement appearing on the item.  Differing forms of the series statement that are significant should be included in a series authority record.

Display constant

The word Series: may be generated on output preceding the information given in this field.

Second indicator - Nonfiling characters

The second indicator specifies the number of nonfiling characters to be ignored for sorting purposes.  Initial articles are omitted according to CONSER policy; therefore, the second indicator is always set to value "0."


For serials, the most commonly used subfields are:  $3, $a, $v, $x.  For a description of other subfields defined for this field, see Headings - General Information.

Prior to 2009, series for which the transcribed form and the traced form were different (Series traced differently), was transcribed in field 490/1 or 5XX and the traced form was in an 8XX field.  Examples where field 830 was paired with field 490/1 below are being retained to help catalogers interpret records coded before 2008 or for when they chose to transcribe the series statement in field 490/1 (Series traced) in addition to providing the series added entry in field 830.

$a  Uniform title.

Subfield $a contains the title of the series or the uniform title heading when one has been established.  When the uniform title heading contains a parenthetical qualifier, it is included in subfield $a.

$v  Volume/sequential designation.

Subfield $v contains the volume or number of the series when the number is constant for all issues of the serial or when limited issues of the serial are issued in the series.

490 1# $3 <1982/83->: $a Agriculture handbook ; $v no. 305

490 1# AFRP ; $v 110-1

[Field is optional.]

830 #0 Air Force recurring publication ; $v 110-1.

$x  International Standard Serial Number.

Subfield $x contains the ISSN of a series.  The ISSN is an agency-assigned data element.  ISSNs are assigned to publications by national centers under the auspices of the ISSN Network.

In order to allow for accurate sorting of series access points and predictable validation of the access point and ISSN strings, append $x (International Standard Serial Number) to the end of the field as the final subfield.  Do not add any punctuation to $x, except for the hyphen in the middle position of the ISSN.

490 1# JARE data reports, $x 0075-3343. $a Meteorology

[Field is optional.]

830 #0 JARE data reports, $x 0075-3343.

830 #0 JARE data reports. $p Meteorology.

NOTE:  This positioning of subfield $x applies to 8XX fields only; follow conventional AACR2/MARC 21 practices for recording ISSNs in 490 fields, when applicable.

$3  Materials specified.

Subfield $3 contains the part of the described materials to which the field applies.  Follow the volume numbering, chronological designation, publication date, etc., given in $3 with a colon (:).  If the volume numbering, chronological designation, publication date, etc., represents incomplete information designated by a hyphen (-), insert a single space between the hyphen and the colon for clarity in displays.

830 #0 $3 1980- : $a DHEW publication, $x 0090-0206.
