Information about the data source to which the described item is related. Use for information about other files, printed sources or collection procedures. See " 76x-78x  Linking Entry Fields–Introduction" for more information.

1st Indicator

Note controller. A value that specifies whether or not a display note is to be generated from the field. These values could be used to control printing. However, field 786 does not print. Nevertheless, you should enter the values as if it does.
 
Display note. A note is generated from the data in the linking entry field or from the related record. Use to indicate that field 580 (Linking Entry Complexity Note) is not present.
 
1 Do not display note. A note is not generated from the data in the linking entry field or from the related record. Use 1st indicator value 1 when the display constant associated with the linking field does not adequately describe the relationship. Use field 580 (Linking Entry Complexity Note) for the note.

2nd Indicator

Display constant controller. A value that controls the generation of a display constant preceding the data in the linking entry field.
 
blank character Data source. A value that generates the display constant Data source:.
 
8 No display constant generated. A value that specifies that a display constant is not generated. Use subfield ‡i when special introductory text is needed.
