NOTE: If contributing a name authority record to NACO, follow NACO procedure for new national-level authority records located in TPOT.
Sometimes a personal name heading being created will conflict with or normalize to match another heading in the LCNAF or InnoPac's Authority File. Normalization refers to a computer edit that eliminates all diacritics and most punctuation (except first comma after subfield a), and converts all letters to uppercase and all modified letters to their unmodified equivalents.
If neither heading can be modified to differentiate it from the other, an authority record representing more than one person with the same name will need to be created. These are called undifferentiated personal name authority records (also called non-unique name authority records).
Procedure:
1. If the heading being created will exactly match or will normalize to exactly match another heading in the NAF, examine the heading to see if it is for a differentiated personal name (heading represents a unique name) or for an undifferentiated personal name. If it is the latter, skip to section 4 below.
2. If the authority record is for a differentiated personal name, try to resolve the conflict for either the heading being created or the heading already in the Authority File. See AACR2 22.17-19 and consult appropriate reference sources to do so.
3. If the conflict cannot be resolved, it will be necessary to change the existing authority record into a heading for an undifferentiated personal name, per AACR2 22.20.
A. For each person represented by the authority record, supply two 670 citations for the name on the work in hand. The first will contain an informal descriptive term for the person, consisting of the title of the work cataloged and the person’s relationship to it, and will be in brackets. The second will be a standard 670 note.
Pattern:
670 _ _ [Author (or editor, etc.) of Title of work in hand]
670 _ _ Title, date: $b location (citation of name)Example:
670 _ _ [Author of A history of witchcraft]
670 _ _ A history of witchcraft, 1981: $b t.p. (Jean Mason)B. Add a bracketed 670 field for the first person already listed in the authority record, per step 3.A. above. This will be the first 670 field for that person.
4. If the authority record is already an undifferentiated personal name, add the citations to the record, following steps 3.A-B above.
Example of an undifferentiated personal name:
100 1 0 Stewart, John
670 _ _ [Editor of The Best of Tracks]
670 _ _ The Best of Tracks, 1975 (a.e.) $b cover (John Stewart, editor)
670 _ _ [Author of Of no fixed abode]
670 _ _ Of no fixed abode, 1975: $b t.p. (John Stewart) jkt. (lecturer in soc. admin.,
Univ. of Lancaster)
670 _ _ [Author of Ulster D.V.]
670 _ _ Ulster D.V., 1972: $b t.p. (John Stewart) introd. (former missionary; pastor,
Woodvale Meth. Church, Belfast)
670 _ _ [Editor of Made for television]
670 _ _ Made for television, 1985: $b t.p. (John Stewart) p. iv (Television access officer at the British Film Institute)
