Description/Instructions

Field 580 is used to express complex relationships that cannot be accurately generated by using the display constants associated with the linking entry fields (765-787). It is also used for regular-print reprints to provide details of the original. Notes for relationships involving the 776 field (Additional physical form entry) are recorded in field 530.

With the exception of special cases noted below, one or more linking entry fields (765-787) is also input, in addition to field 580. When field 580 is used in conjunction with a linking field, set the first indicator in the linking field to value "1" so that it will not print an additional note.

Field 580 used in the following situations:

1. When optional date information is provided with a "continued by" or "absorbed by" note.
