Optional Fields in New NARs

General

In addition to previously enabled 043, 053, and 781, a number of new fields were added to MARC Authorities as a result of the transition to RDA. As of now, NACO policy defines all of these fields as optional. The new fields help to define what RDA considers information in support of identification. Even if they are not used, keep them in mind when deciding on what information to record in 670; another cataloger should be able to use the information in 670 to create the appropriate 3xx field without the book in hand.

043 Fields: Geographic Area Codes

Optional practice: In a NAR for a geographic name heading (coded 151), you may include an 043 field giving the geographic area code. Both indicators should be blank. No justification is needed in a 670 field.

043     $an-us-wa
151     $aSeattle (Wash.)

For more information, see the MARC Code List for Geographic Areas, the LC Descriptive Cataloging Manual (DCM Z1 043 field), and the NACO Participants' Manual (NPM p. 21: section I, 043 field).

For more information, see the MARC Code List for Geographic Areas, the LC Descriptive Cataloging Manual (DCM Z1 043 field), and the NACO Participants' Manual (NPM p. 21: section I, 043 field).

046 Fields. Special Coded Dates

Generally consider it best practice to create a 046 field even if the information is already recorded in 670 for subfields $f, $g, $s, and $t where appropriate. For additional examples and guidelines see:

046 for NARs, with Examples

046 EDTF, Personal Name, & Active Date Examples

046 Corporate Names

053 Fields: LC Classification Numbers for Literary Authors

Optional practice: You may record an LC classification number for a literary author in an 053 field in a NAR only in one of the two following situations: you find the number in the 050 of a bibliographic record created and input by LC (040 $a DLC $c DLC) or you have requested an 053 from LC using their online request form. If adding an 053 field, only the $a portion of the full call number is to be recorded. The second indicator should be 0. No justification is needed in a 670 field.

053 fields should never be used on undifferentiated name records or to record PZ numbers.

Multiple 053 fields may be used for literary authors who write in more than one language. Qualify the 053 with the language in $c (without using parentheses) in such cases.

053   0 $aPS3527.A15$cEnglish
053   0 $aPG3476.N3$cRussian

For more information, see the LC Classification Manual (SCM F 632), the LC Descriptive Cataloging Manual (DCM Z1 053 field), and the NACO Participants' Manual (NPM p. 22: section I, 053 field).

If you want to record an LC classification number in a NAR and you cannot do it using an 053 field, update the record in ORBIS using an 090 field (see below). 

336 Field. Content Type

Under current LC/PCC practice, do not enter field 336 in NARs

368 Field. Other Attributes of Person or Corporate Body.

381 Field. Other Distinguishing Characteristics of Work or Expression.

Examples (NACO RDA Training, MARC 21 Authorities, RDA in NACO Bridge Training)

781 Fields: Geographic Subdivision

Optional practice: In a NAR for a geographic name heading (coded 151), you may include a 781 field giving the form of the heading to be used in a geographic subdivision. The second indicator in the 781 field should be 0. No justification is needed in a 670 field.

151     $aSydney (N.S.W.)
781   0 $zAustralia$zSydney (N.S.W.)

Do not add a 781 field to a record for a geographic name heading that is not appropriate for use as a subject added entry (008/15 value "b"), such as the earlier name of a jurisdiction that has undergone a linear name change, for example, Ceylon.

Please use caution when exercising this option! Make sure you are constructing the geographic subdivision correctly. For more information, see the LC Subject Cataloging Manual (SCM H 690 through SCM H 1055), the LC Descriptive Cataloging Manual (DCM Z1 781 field), and the NACO Participants' Manual (NPM p. 67: section I, 781 field).
