Field definition and scope:

Field 555 contains a tracing for a genre/form term 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 genre/form term to a related established heading.

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

Field 555 is repeatable.

Guidelines for applying content designators:

The content designators identify the subelements occurring in genre/form term headings constructed according to generally accepted thesaurus-building conventions (e.g., Art & Architecture Thesaurus).

Genre terms for textual materials designate specific kinds of materials distinguished by the style or technique of their intellectual contents; for example, biographies, catechisms, essays, hymns, or reviews.

Form terms designate historically and functionally specific kinds of materials as distinguished by an examination of their physical character, characteristics of their intellectual content, or the order of information within them; for example, daybooks, diaries, directories, journals, memoranda, questionnaires, syllabi, or time sheets.

In the context of graphic materials, genre headings denote categories of material distinguished by vantage point, intended purpose, characteristics of the creator, publication status, or method of representation.

Content designator history:

Prior to the definition of the X55 fields, X50 (Topical Terms) fields were used for genre/form term headings.

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.
