Non-unique records: Guidelines and Examples
The heading on an undifferentiated personal name record (also known as a non-unique record) represents more than one individual. When changing an existing unique personal name record to a non-unique record, change the value in the UPN fixed field from "a" to "b".
In the following examples, notice the bracketed 670 field
preceding the 670 field(s) for each person represented on the record.
When adding a person to an existing record that is not already non-unique,
you must add this field before the first 670 field for the person for
whom the record was originally created. If you cannot determine the type
of authorship involved, use Added entry on ... or Entry on ...
with the title proper from the following 670 citation. Also add
two 670 fields for the work you have cataloged, according to the following
Add a 675 field to list the reference sources you have consulted.
