Please note that the example provided to illustrate the use of subfield $u (Uniform Resource Identifier) appears to be erronesouly tagged 678 instead of 670:
678 ## $aThe official Stephen King web presence, viewed Oct. 26, 2001: $bThe man (Stephen Edwin King; b. Portland, Maine, 1947) $u<http://www.stephenking.com>
The Stephen King Web site has been cited to document his place and date of birth, which is the kind of information normally included in field 670 for a personal name heading. Although field 678 also may be used to provide biographical data, I have not seen this field currently used in authority records created for personal names.
The example provided to illustrate the use of subfield $u in field 678 (Biographical of Historical Data) clearly is in keeping with the use of that field for providing detailed background information not normally included in field 670. The latter is used to justify heading forms or variants, as well as to provide data that form part of the heading/reference string, such as life dates or titles.

URLs in Name Authority Records
The December 2005 update to DCM Z1, available on the PCC Web site at:
provides guidelines on the use of subfield $u in the 670 field. URIs in 670 fields are now only appropriate for use in subfield $u; they should not be used in subfields $a or $b. The information in support of this is at the above address under the subsection of 670 headed Internet resources on p. 5 of the PDF
CPSO continues to see new name authority records with URIs put in subfields $a or $b. Please keep in mind this recent change in practice when creating new authority records.
