2. Choose whether you want the exception report to include a list of the deleted
subject headings. For faster processing, choose Summary only where the
report includes only summary information and processing errors.
3. Click Delete. A progress dialog appears.
Warning: All changes made to your copy records are immediate. You cannot
reverse changes that have been made by canceling the process.
4. When its Cancel button changes to Close, click it to return to the main
window of Cataloging.
After the processing finishes, Cataloging generates an exception report. The
Summary contains the number of records modified and the number of tags
deleted, along with any processing errors. The Summary and Deleted Headings
List includes a list of the deleted subject headings. Neither one lists the titles of
the bibliographic records that were modified.
If you have authority records and cross-references in your database, you may
have some blind crossĆreferences after running this deletion. We recommend that
you rebuild your crossĆreferences (from the Tools menu) after performing the
Global Delete Subject Headings by Source. Please allow extra time for this. For
instructions on rebuilding cross-references, see page 346.
If you would like to preview" the results of deleting one or more types of
headings:
1. Perform an export of all your MARC records. To minimize the file size, do
not select the Include Copy Information check box.
2. Run the Global Delete Subject Headings by Source.
3. Rebuild your cross-references.
4. Perform several searches in Cataloging or OPAC.
5. If you find that this global delete reduced your subject access points to an
unacceptable level, import the exported file. Make sure to import by control
number (see page 296).
6. Rebuild your cross-references again.
DX-enabled union catalogs and members
Please note that the deletions occur only in the local database. DX (Data transfer)
is automatically suspended while the Global Delete Subject Headings by Source
feature is running. Once the processing is finished, DX resumes automatically.
This suspension ensures that the deletions are not propagated throughout the
union.
Also be aware that you may need to repeat this global delete periodically. Data
Exchange transmits records according to its survival rules, where the records
with the most complete information are saved to the union catalog database and
sent to members. Depending on your participation level and on the completeness
of the records in your union catalog, you may later receive records that contain
the deleted heading type.
