Field definition and scope:

Field 551 contains a tracing for a geographic name see also from reference.  It is used in an established heading record or an established heading and subdivision record to trace a see also from reference from an established geographic name to a related established heading.

The National level record requirement for this field is Mandatory if applicable.

Field 551 is repeatable.

Guidelines for applying content designators:

The content designators identify the subelements occurring in geographic name headings constructed according to generally accepted cataloging and thesaurus-building conventions [e.g., Anglo-American Cataloguing Rules (AACR 2), Library of Congress Subject Headings (LCSH)].

Jurisdiction names (including those that are ecclesiastical entities) alone or followed by subject subdivisions are X51 geographic names.

A corporate name, a form subheading, a title of a work, and/or a city section name entered under the name of a jurisdiction are contained in the X10 fields.

Geographic names used in phrase subject headings (e.g., Iran in the Koran) are contained in the X50 fields.

A geographic name that is authorized for use only as a subject subdivision part of an extended subject heading is contained in a 181 (Geographic Subdivision) field.

Content designator history:

Second Indicator - Nonfiling characters  [obsolete]:  The second indicator position was made obsolete in fields 151, 451, and 551 in 1993.  The values were:  0-9 (Number of nonfiling characters present).

Subfield $b - Name following place as entry element  [obsolete]:  Subfield $b was made obsolete in fields 151, 451, and 551 in 1987.  A city section name entered under the name of a jurisdiction is contained in an X10 field.  Records created before this change may contain an X51 field with a subfield $b for this type of name.

Subfield $g - Miscellaneous information  [new, 2014]

Subfield $i - Reference instruction phrase  [redefined, 2009]:  Subfield $i was renamed Relationship information and broadened to include relationship designations in addition to textual reference phrases.  The subfield was changed from Not repeatable (NR) to Repeatable (R).

Subfields  $v - Form subdivision  [redefined]

$0 - Record control number  [new, 1997]

$0 - Record control number  [redefined, 2010]

$3 - Authority record control number  [obsolete, 1997]  [CAN/MARC only]

In USMARC, from 1993 to 1995, subfield $v was defined as Record control number in the 7XX Heading Linking Entry fields.  When subfield $v was adapted for form subdivisions in MARC bibliographic and authority heading fields in 1995, subfield $v was redefined as Form subdivision.  In 1997, subfield $0 was added as Record control number in 5XX and 7XX fields.

Subfield $w/0 - Print constant code  [redefined, 1997]  [CAN/MARC only]:  The following values were redefined:  g (Full name), h (Real name), and i (Real name (reputedly)).  The following values were made obsolete:  j (Name originally), k (Name in religion), l (Secular name), m (Stage name of), o (Variant name), p (Abbreviated name), q (Official name), r (Broader term), s (Narrower term), x (Print constant generated from tag value), and z (Text carried in subfield $i).

Subfield $w/0 - Special relationship

Code r - Relationship information in subfield $i or $4  [new, 2009]

Subfield $w/1 - Tracing use restriction

Code h - No reference structures  [new, 2007]

Subfield $w/2 - Earlier form of heading

Code x - Tracing is not the form of heading established under earlier cataloguing rules  [obsolete, 1997]  [CAN/MARC only]

Subfield $w/3 - Reference display

Code e - Note only generated from the tracing  [obsolete, 1997]  [CAN/MARC only]

Code i  - Invisible see from reference  [obsolete, 1997]  [CAN/MARC only]

Code x - Reference is generated from the tracing  [obsolete, 1997]  [CAN/MARC only]

Subfield $w/4 - Formerly established heading code  [obsolete, 1997]  [CAN/MARC only]:  The following values were defined:  d (Formerly accepted heading replaced by the heading in the 1XX field), s (Formerly accepted heading replaced by other headings, one of which is in the 1XX field), and x (Not a formerly accepted heading).

Subfield $4 - Relationship code  [new, 2009]

Subfield $4 - Relationship code  [renamed, 2017] [redescribed, 2017]:  Subfield $4 was renamed to Relationship and redescribed to allow for the recording of relationship URIs in addition to MARC and non-MARC codes.
