NOTE:  See MARC 21 Format for Bibliographic Data (773 Host Item Entry) for code definitions not given below.


Field 773 contains information concerning the host item for the component part/subunit described in the record.  Use field 773 for serials only when Leader/07 (Bibliographic level) is set to value "b" (for serial component part).  This linking entry facilitates the location of the item that contains the component part or subunit that is described in the record.  Input information in subfield $g that assists in locating the component part within the bibliographic item.

Display constant


Linking relationships

Field 774 (Constituent Unit Entry) can be paired with field 773 though reciprocal use is not mandatory.  The record for the host item may instead include a title added entry field for the component part or subunit.


The first indicator determines the note display.  Set the first indicator to value "0" when a note is to be generated from the linking field.  Set the first indicator to value "1" when a note is input in field 580 that identifies the host item.

The second indicator determines whether the display constant is generated or whether text added in subfield $i is intended to be displayed with the other data in the field.  When adding text to subfield $i to display with the field, set the second indicator to "8."


The most common subfields are (in input order):  $a, $s, $t, $g, $x, $w.  For a description of subfields defined for this field, see Linking Entry Fields - General Information.
