DCM Z1: 663 Complex See Also Reference - Name
General:
The 663 field contains the explanatory text and authorized access points for relationships between a 100 (established name) and other 100s (established names) that cannot be adequately conveyed by one or more simple see also references generated from 500 fields.
Generally, this situation occurs when a person uses more than two identities, when more than one person shares an identity with one or more others, or when multiple persons use the same pseudonym independent of each other or as a result of some other arrangement.
The text of the 663 may be adjusted to fit extraordinary situations; however, keep the text as simple as possible, allowing the MARC fields and coding to convey the information desired.
Do not use the 663 technique to show relationships between corporate bodies or between persons and corporate bodies.
More information on creating NARs for persons with alternate identities is found in the FAQ - LC/PCC RDA and AACR2 Practice for Creating NARs for Persons Who Use Pseudonyms available at: http://www.loc.gov/catdir/cpso/pseud.pdf.
Only two identities:
When only two NARs are created for a person, the NARs are generally connected with 500 see also references and no 663 field. However, when one of the NARs is for a joint pseudonym or a pseudonym used by several persons working independently of each other, the 663 technique is used.
More than two identities - basic authorized access point and references:
When more than two authorized access points are created for the same person, identify a "basic" authorized access point using the 663 field technique. This decision is based on the desire to simplify the reference structure and to assist catalogers in determining which name to use as the subject of biographical or critical works. The "basic" authorized access point should be determined by the predominantly used form of name or, lacking sufficient evidence, by choosing the real name of the person as the "basic" form.
On the authority record for the "basic" name authority record add 500 see also references with a subfield $w coded "nnnc" from all other names used. Justify the 500 in 670 citations according to normal practice. Provide a 663 field listing all the other names with the following text (may be adjusted to fit the situation):
663 ## $a For works of this author written under other names, search also under: $b [established form of name] $b [established form of name]
On each of the other name authority records, trace a 500 see also reference with subfield $w coded "nnnc" from the "basic" name, justifying that reference in a 670 citation, according to normal practice. Other names may be mentioned in the 670 if it is convenient to do so. Provide a 663 field with the following or similar text (may be adjusted to fit the situation):
663 ## $a Works by this author are entered under the name used in the item. For a listing of the names used by this author, search also under: $b [established form of name chosen as the basic heading]
When the author uses another new name, create a new name authority record for that name and also add it to the reference structure and 663 listing on the authority record for the "basic" name. References to the new name in the 500 and 663 fields are only added to the "basic" NAR.
Examples:
"Basic" NAR:
100 1# $a Harris, John, $d 1916-1991
500 1# $w nnnc $a Hennessy, Max, $d 1916-1991
500 1# $w nnnc $a Hebden, Mark, $d 1916-1991
663 ## $a For works of this author written under other names, search also under: $b Hebden, Mark, 1916-1991 $b Hennessy, Max, 1916-1991
NAR for first 500 on "basic" NAR:
100 1# $a Hennessy, Max, $d 1916-1991
500 1# $w nnnc $a Harris, John, $d 1916-1991
663 ## $a Works by this author are entered under the name used in the item. For a listing of other names used by this author, search also under: $b Harris, John, 1916-1991
NAR for second 500 on "basic" NAR:
100 1# $a Hebden, Mark, $d 1916-1991
500 1# $w nnnc $a Harris, John, $d 1916-1991
663 ## $a Works by this author are entered under the name used in the item. For a listing of other names used by this author, search also under: $b Harris, John, 1916-1991
Joint pseudonyms:
A joint pseudonym represents one identity used by two or more persons working in collaboration with each other. If a person uses a joint pseudonym and another name (as found in the catalog), the "basic" authorized access point technique is used.
Examples:
NAR for joint pseudonym:
100 1# $a Phillips, Mark
500 1# $w nnnc $a Garrett, Randall
500 1# $w nnnc $a Janifer, Laurence M.
663 ## $a Joint pseudonym of Randall Garrett and Laurence M. Janifer. For works of these authors written under their own names, search also under: $b Garrett, Randall $b Janifer, Laurence M.
NAR for first 500 on joint pseudonym NAR:
100 1# $a Garrett, Randall
500 1# $w nnnc $a Phillips, Mark
663 ## $a For works of this author written in collaboration with Laurence M. Janifer, search also under: $b Phillips, Mark
NAR for second 500 on joint pseudonym NAR:
100 1# $a Janifer, Laurence M.
500 1# $w nnnc $a Phillips, Mark
663 ## $a For works of this author written in collaboration with Randall Garrett, search also under: $b Phillips, Mark
Pseudonyms used by multiple persons:
When multiple persons working independently of each other use the same pseudonym and one or more other names (as found in the catalog), the "basic" authorized access point technique is used.
Examples:
NAR for pseudonym used by multiple persons:
100 1# $a Robeson, Kenneth
500 1# $w nnnc $a Dent, Lester, $d 1904-1959
500 1# $w nnnc $a Goulart, Ron, 1933- [...]
663 ## $a Pseudonym used by multiple authors writing individually. For works of these authors written under their own or other names, search also under: $b Dent, Lester, 1904-1959 $b Goulart, Ron, 1933- [...]
NAR for first 500 on pseudonym used by multiple persons NAR:
100 1# $a Dent, Lester, $d 1904-1959
500 1# $w nnnc $a Robeson, Kenneth
663 ## $a For works of this author written under another name, search also under: $b Robeson, Kenneth
NAR for second 500 on pseudonym used by multiple persons NAR:
100 1# $a Goulart, Ron, $d 1933-
500 1# $w nnnc $a Robeson, Kenneth
500 1# $w nnnc $a Silva, Joseph, $d 1933- [...]
663 ## $a For works of this author written under other names, search also under: $b Robeson, Kenneth $b Silva, Joseph, 1933- [...]
[Author has a pseudonym used by multiple persons and individual pseudonyms.]
