|Supply to cite the resource catalogued and to justify the authorized access point, including additions that are part of the authorized access point, variant access points and certain identification elements.
|Supply to:
* cite the resource catalogued;
* justify all elements for the authorized access point and variant access points, including additions that are part of the access points;
* justify the Information recorded in the 046, 3XX, or 678 field, when subfield $v is not defined to record a source of information or is not used
* justify related access points that express relationships (fields 5XX).
''Note:'' Subfield $v may be used in place of field 670 to justify information recorded in fields 046 and 3XX when it has been defined for this purpose in these fields.
''Exceptions:'' It is not necessary to add 670 fields to justify references in the following cases:
* references justified by instructions or policy statements only, usually because the reference is derived from inverting, shortening, etc., the authorized access point or giving a substitute form of the access point;
* references made on the basis of the cataloger's awareness of different romanizations or orthographies;
* name/title cross-references derived from the work being cataloged, from other works cataloged under the same authorized access point, or from information in standard reference sources;
* references to predecessor/successor names of corporate bodies reflecting changes due to national or orthographic reform,
* references to changes in names of government bodies due to an official language change, or changes involving only a parent body to which the body being established is subordinate.
