NACO LSP Usage (LC Guidelines: Tracing and Reference Fields - General Information)

Alternate Graphic Representation:

Do not use subfield $6 (Linkage) in any of the tracing and reference fields. Records containing alternate graphic representation fields are not within the scope of the present NACO LSP project. Subfield $6 has not been implemented in the LC system.

Reference Fields:

Subject authority records are not within the scope of the present NACO LSP project. Do not use the following fields:

260 Complex See Reference - Subject

360 Complex See Also Reference - Subject

Do not use field 665 (History Reference). Instead, use 5XX See Also From Tracing fields with a subfield $w/0 (Control subfield/Special relationship) containing code a (Earlier heading) or b (Later heading) as appropriate.

LC NACO must be consulted before field 663 (Complex See Also Reference - Name), 664 (Complex See Reference - Name), and 666 (General Explanatory Reference - Name) are used.

Tracing Fields:

Subdivision records are not within the scope of the present NACO LSP project. Do not use the following fields:

480 See From Tracing - General Subdivision

481 See From Tracing - Geographic Subdivision

482 See From Tracing - Chronological Subdivision

580 See Also From Tracing - General Subdivision

581 See Also From Tracing - Geographic Subdivision

582 See Also From Tracing - Chronological Subdivision

Subfield Codes:

Do not use the following subfield codes in 4XX and 5XX tracing fields:

$i - Reference instruction phrase

$5 - Institution to which field applies

Subfield $5 has not been implemented in the LC system.

$w - Control subfield in 4XX See From Tracing fields:

____/0 Special relationship

Do not use the following codes:

a- Earlier heading

b - Later heading

d - Acronym

f - Musical composition

g - Broader term

h - Narrower term

i - Reference instruction phrase in subfield $i

Code n (Not applicable) may be used when a subsequent character position in subfield $w is coded.

____/1 Tracing use restriction

Do not use the following codes:

a - Name reference structure only

b - Subject reference structure only

c - Series reference structure only

d - Name and subject reference structures

e - Name and series reference structures

f - Subject and series reference structures

g - Name, subject, and series reference structures

Code n (Not applicable) may be used when a subsequent character position in subfield $w is coded.

____/2 Earlier form of heading

Do not use the following code:

o - Earlier established form of heading (other authority file)

Code a (Pre-AACR 2 form of heading (national name authority file)) is used when the tracing is for a linking reference from a pre-AACR 2 heading.

Code e (Earlier established form of heading (national authority file)) is used primarily when a reference from the former heading is appropriate under normal AACR 2 reference practice, and the former heading is not covered by code a. This includes former headings that were previously coded either as AACR 2 (code c) or Non-AACR 2 form used with AACR 2 (code d). A reference should not automatically be made from the former heading in order to supply code e.

Code n (Not applicable) may be used when neither code a nor e applies and a subsequent character position in subfield $w is coded.

____/3 Reference display

Do not use the following codes:

c - Reference not displayed, field 663 used

d - Reference not displayed, field 665 used

Code a (Reference not displayed) or b (Reference not displayed, field 664 used) may be used when appropriate for suppressing a cross reference display.

Code n (Not applicable) allows the generation of a cross reference display and need not be coded in subfield $w/3.

$w - Control subfield in 5XX See Also From Tracing fields:

____/0 Special relationship

Do not use the following codes:

d - Acronym

f - Musical composition

g - Broader term

h - Narrower term

i - Reference instruction phrase in subfield $i

Code a (Earlier heading) or b (Later heading) may be used when appropriate for a 1XX/5XX relationship.

Code n (Not applicable) may be used when neither code a nor b applies and a subsequent character position in subfield $w is coded.

____/1 Tracing use restriction

Do not use the following codes:

a - Name reference structure only

b - Subject reference structure only

c - Series reference structure only

d - Name and subject reference structures

e - Name and series reference structures

f - Subject and series reference structures

g - Name, subject, and series reference structures

Code n (Not applicable) may be used when a subsequent character position in subfield $w is coded.

____/2 Earlier form of heading

Do not use the following codes:

a - Pre-AACR 2 form of heading (national name authority file)

e - Earlier established form of heading (national authority file)

o - Earlier established form of heading (other authority file)

Code n (Not applicable) may be used when a subsequent character position in subfield $w is coded.

____/3 Reference display

Do not use the following codes:

b - Reference not displayed, field 664 used

d - Reference not displayed, field 665 used

Code a (Reference not displayed) or c (Reference not displayed, field 663 used) may be used when appropriate for suppressing a cross reference display.

Code n (Not applicable) allows the generation of a cross reference and need not be coded in subfield $w/3.
