667 Field (Section II: Additions and Changes to Authority Records)
1. When adding a "Not the same as" or "Cannot identify with" 667 note to a new authority record, it may be helpful to add a corresponding 667 to the existing record.
Example:
new record being added:
100 1# $a Thomas, Edward, $c printer, of London
400 1# $a Thomas, E. $q (Edward), $c printer, of London
667 ## $a Cannot identify with: Thomas, Edward, printer
670 ## $a The interesting history, of little King Pippin, 1820: $b p. 40 (E. Thomas; printer, Golden Lane, Barbican, London)
670 ## $a Todd, W.B. Directory of printers ... London & vicinity 1800-1840, 1972 $b (Thomas, Edward; printer in London, active 1808-1837)
existing record in the LC/NAF, 667 added:
100 1# $a Thomas, Edward, $c printer
667 ## $a Cannot identify with: Thomas, Edward, printer, of London
670 ## $a Little Tommy, 1858: $b t.p. (Edward Thomas; printer, Chester, England)
Note that this information is better reflected in 670 notes.
2. If a linking reference would normalize to the same form as the heading or another reference on the same record or to the same form as a heading on another record, add an "Old catalog heading" 667 note. It may also be necessary to use this 667 note if the linking reference method of tracing a pre-AACR2 LC heading is not appropriate (see DCM Z1, Introduction).
Example:
100 0# $a Napoleon $b I, $c Emperor of the French, $d 1769-1821
667 ## $a Old catalog heading: Napoléon I, Emperor of the French, 1769-1821
