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.
