Note: ‡w is repeated in order to accommodate both the MARC standard ("System control number of the related record preceded by the MARC code, enclosed in parentheses, for the agency to which the control number applies.") and machine linking (the OPAC needs an exact match for the system control number in order to create the link).
Note: ‡w has to be an exact match for the Hamnet BibID in order for the link to be generated.

MARC field 787 in the Bibliographic format contains information concerning the work related to the target item when the relationship does not fit any of those defined in fields 760-785. This field is repeatable.

Basic use and searching

Basic use

  • Use for linking Hamnet records with uncommon or nonspecific relationships


Searching

  • [indicate whether the field is searchable in Hamnet drop-downs, or only in the staff module and Command Line search] To be determined.

Commonly-used tags

Indicators
1st indicator – Note controller 

0 - Display note

2nd indicator – Display constant controller 

# - Related item
8 - No display constant generated

Subfield delimiters

$i - Relationship information (R) 
$a - Main entry heading (NR)
$t - Title (NR)
$d - Place, publisher, and date of publication (NR)
$h - Physical description (NR)
$n - Note (R)
$w - Record control number (R)

Policy and formulation

  • Need to determine: will we prefer use of subfield $n or an accompanying MARC 580 Linking Entry Complexity Note to describe the relationship?
  • As of Sept. 3, 2017, Hamnet is configured so that the presence of a Hamnet Bib ID in 787ǂw automatically creates a "Records for related items" link.

Examples

Record is for printed book. 

787 0  ‡a Westerhout, Arnold van, 1651-1725. ‡t Eques Leenae Neapoli. ‡d [Rome?] : [Arnold van Westerhout], [1711?] ‡h 1 plate ; 204 x 139 x 10.5 mm. ‡n Copperplate used to print plate 67 of  manifestation.  ‡w 340195

Record is for copperplate 

787 0  ‡t Ordinum equestrium, ac militarium brevis narratio. ‡d [Venice] : pressò L'Orlandi, 1715. ‡h [2], CXXXXI, [3] p., [246] p. of plates : ill., coats of arms, ports. ; 27 cm (4to) ‡n Manifestation containing, as plate 67, the print made from the copperplate. ‡w 352615

Note: ‡w has to be an exact match for the Hamnet BibID in order for the link to be generated. Repeating ‡w so that the other one has the "(DFo)" called for in the MARC standard doesn't work. Alternatively, the Folger BibID could go in ‡o and a new Bibliographic Record Linking profile created that matches on ‡o. Note that ‡o is used for Folger call number in some existing records.
