782 Subdivision Linking Entry - Chronological Subdivision (R) (Variable Data Field)
Field 782 contains a chronological subdivision term that is equivalent to the 150 topical term or 182 chronological subdivision field of the same record. It links headings within a system or from different thesauri or authority files.
The National level record requirement for this field is Optional.
Field 782 is repeatable.
Guidelines for applying content designators:
The content designators identify the subelements occurring in chronological subdivision headings constructed according to generally accepted thesaurus-building conventions (e.g., Library of Congress Subject Headings, Medical Subject Headings).
A chronological subdivision is used as a subdivision portion of an extended subject or index term access field in bibliographic records.
A chronological term that is used as the lead element of an established heading record is contained in a 150 (Heading - Topical Term) field.

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 and subfield $u was defined as Record control number. In 1997, subfield $0 was added as Record control number in 5XX and 7XX fields and $u was made obsolete.
Subfield $w/1 - Replacement complexity [new, 2002]: In 2002, subfield $w/1 was defined with the following codes: a (Heading replacement does not require review); b (Heading replacement requires review); and n (Not applicable).
Subfield $1 - Real World Object URI [new, 2017]
Subfield $4 - Relationship code [new, 2014]
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.
