MARC field 774 in the Bibliographic format contains information about a constituent unit associated with a larger bibliographic unit. It is used in the parent record, with reciprocal [[MARC 773 Host Item Entry|773 fields]] in the child (or analytic) records containing information about the larger bibliographic unit.
As of September 4, 2017, Hamnet is set up so that a non-displaying 774 generates a list of contents (up to three records) or a link to a separate page of contents (if more than three records) based on an exact match between the text in the 774‡o of the main record and the text of the 773‡t of the target records. See http://hamnet.folger.edu/cgi-bin/Pwebrecon.cgi?BBID=94535 for example.

Policy and formulation

  • Routinely add a 774 when cataloging a component item that is part of a larger bibliographic unit. Examples: a supplemental issue of a journal, a single porcelain from the Babette Craven collection, a print from a book that is being cataloged as an in-analytic record.
  • Voyager generates an embedded "Related items" list into a record based on the contents of the 774 ‡o. There are two options:
    • Add the BIB ID - without a prefix, unlike the ‡w - of a target record.
‡t British theater (1808) ‡g vol. 11 ‡o 67409 ‡w (DFo)67409
    • Add the exact text string found in the 773 ‡t of a target record. (In the example below, all Craven collection items have a reciprocal 773 ‡t Babette Craven collection of theatrical memorabilia.)
‡n Records for items in the collection all have a 773 ‡t with the title: ‡o Babette Craven collection of theatrical memorabilia

Searching

  • If the field contains a ‡t, that text string will be included in any Title search in Hamnet.
  • Otherwise, the field is not searchable in Hamnet or Voyager.
