Linking relationships
Field 773 (Host Item Entry) can be paired with field 774 though reciprocal linking is not mandatory. The record for the Constituent unit may instead contain an added entry for the Host item.
First indicator - Note controller
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 constituent unit.
Second indicator - Display constant controller
The second indicator position contains a value that controls the generation of a display constant preceding the data in the linking entry field.
Use value "#" for the 774 field display constant. The display constant Constituent unit: may be generated.
8 No display constant generated.
Use value "8" to indicate that no display constant is to be generated.
The introductory phrase "Constituent unit:" that is displayed in notes with the data recorded in field 774 is not carried in the MARC 21 record. It may be system generated as display constants associated with the second indicator value "#."
