04/04 Chapter 23 Using the MARC Editor 283
If a bibliographic record uses the authorized form in an indexed subject, author,
or series heading, Cataloging can use the tracing information in the authority
record to create crossreferences.
Important:
Crossreferences are created automatically if you choose to create
them as authority records are saved (see Setting up miscellaneous
Cataloging options," page 55). However, in order to create a
crossreference, the bibliographic record must exist when the
authority record is saved.
Whenever you do significant maintenance to your database, you'll need to
rebuild your crossreferences to ensure that they stay accurate (see Rebuilding
crossreferences," page 346).
See also:
For information about authority tags or to see which bibliographic tags
are indexed by Cataloging, see Appendix B, Bibliographic and authority tags."
Fine tuning crossreferences
As explained on page 281, positions 14-16 of the 008 tag define how Cataloging
uses the authority record to create crossreferences. You can create exceptions for
individual 4XX/5XX tags by adding the Control subfield _w to a tag and making
some minor modifications.
Note:
Control subfield _w is only available for 4XX/5XX tags.
By default, subfield _w isn't included. To add subfield _w to a 4XX/5XX tag, use
the instructions on page 275. It is accepted cataloging practice to put subfield _w
first in the tag. (To edit an existing subfield _w, doubleclick the subfield data, or
with your cursor anywhere in the tag, choose Subfield| Edit subfield `w'.)
The Subfield `w' Editor dialog appears:
To suppress or enable cross
references for this tag, select
the appropriate code.
To suppress all crossreferences
for this tag, set this code to a."
Select the appropriate
values from the drop
down lists, and click OK.
Note:
The four coded positions in subfield _w are filled from the left. If you don't
select codes for the leading positions, the system automatically fills them
with n" (not applicable) when you click OK.
Example:
Consider the example on page 282. To limit the SEE ALSO reference to
author searches without affecting the other crossreference, you would add
subfield _w to the 500 tag, and in the Tracing use restriction dropdown list,
select a = Name reference structure only."
