'''''Note:'' This section does not apply to the 781 field used in 151 name authority records to provide geographic subdivision information. See Manual, 781 section, for instructions for that field.'''
 +
 +
'''General'''
 +
The use of an established heading linking entry 7XX field in an NAR or SAR is limited to recording the authorized access point from a national bibliography or in a separate national authority file or a separate equivalence. 
 +
 +
The form of heading in a 7XX field may match the 1XX form or a 4XX form in the same authority record. This is appropriate when the 7XX field form represents a form found in a different authority file than Canadiana.
 +
 +
'''Example:'''
 +
<pre styel="font-family: courrier new;">
 +
100 1# $a Dion, Céline
 +
700 10 $a Dion, Céline $0 (DLC)n 87834212
 +
</pre>
 +
 +
The source of the heading in the 7XX field may be specified using either second indicator value “7” with subfield $2 or a second indicator value that specifies the source. For access points coming from the LC/NACO file, prefer the second indicator with the value "0".
