Information concerning the host item for the constituent unit described in the record (vertical relationship). In the case of host items that are serial or multi-volume in nature, information in subfields $g and $q is necessary to point to the exact location of the component part within the bibliographic item.

When a note is generated from this field, the introductory term In may be generated based on the field tag for display.

Provided in order to enable the user to locate the physical piece that contains the component part or subunit being described. Thus, only those data elements required to assist in the identification of the host item need to be included in the field, such as links to the bibliographic record describing the item and/or descriptive data that identify the host item.


Description of the first indicator position and all subfield codes, as well as input conventions except for display constants, for field 773 are given in the 760-787 Linking Entries-General Information section.


Second Indicator - Display constant controller

Controls the generation of a display constant preceding the data in the linking entry field.

# - In

Used to generate the display constant In:.

8 - No display constant generated

Information may be provided in subfield $i (Relationship information) when special introductory text is needed.
