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 crossreferences.

Important: Crossreferences 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

crossreference, 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 crossreferences to ensure that they stay accurate (see Rebuilding

crossreferences," 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 crossreferences

As explained on page 281, positions 14-16 of the 008 tag define how Cataloging

uses the authority record to create crossreferences. 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, doubleclick 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 crossreferences

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 crossreference, you would add

subfield _w to the 500 tag, and in the Tracing use restriction dropdown list,

select a = Name reference structure only."
