It looks like only 655s with |2 lcgft will be affected. -Ryan

Coming down the pike. If I understand correctly, OCLC is developing software
to do additional authority control in batch mode (that is, not as part of
the cataloging process, but later). 8xx and 655 fields will be now be
controlled through that process, in addition to other fields that are
currently controlled by Connexion. I don't know if they will try to control
subdivisions in 655's, but given the laissez-faire attitude of the rbms
controlled vocabularies toward subdivision practice, I'd hate to have
changes made through controlling that are perfectly legitimate under the
particular thesaurus' principles for use.

Subject: [PCCLIST] Controlling More Headings in WorldCat

Forwarding on behalf of Glenn.

In the research that led to the publication of Online Catalogs: What End
Users and Librarians Want (
<http://www.oclc.org/us/en/reports/onlinecatalogs/default.htm>
http://www.oclc.org/us/en/reports/onlinecatalogs/default.htm) library staff
who use WorldCat ranked the need for increased accuracy in name and subject
headings as a highly desired improvement.  The report on WorldCat quality
issued in September 2011 (
<http://www.oclc.org/us/en/reports/worldcatquality/default.htm>
http://www.oclc.org/us/en/reports/worldcatquality/default.htm) identified a
project to control more headings in WorldCat as a priority during OCLC’s
fiscal year 2012.  The following describes this new controlling effort which
will provide benefit to all users of WorldCat, regardless of which interface
they use.

Current controlling functionality in Connexion. The controlling
functionality currently available in the Connexion applications enables
users to link authority records to headings in master WorldCat bibliographic
records. Cataloger-initiated controlling functions facilitate automatic
updating of headings in bibliographic records.

·         Connexion users initiate matching headings in bibliographic
records to established authority records.

·         The system normalizes the headings in bibliographic records,
matches them with authority records, and inserts the linked heading in the
bibliographic record.

New stand-alone controlling software. OCLC is extending the Control All
functionality by developing a stand-alone batch service that runs
independently.  The software evaluates all bibliographic records in WorldCat
and controls headings as detailed below. 

Records evaluated for processing. The software will evaluate the following
bibliographic records in WorldCat for processing according to different time
schedules: 

·         Master bibliographic records newly added to WorldCat contributed
either through online applications or through batchload will be evaluated
daily.

·         Master bibliographic records changed and replaced in WorldCat will
be evaluated on a pre-determined schedule.

·         Existing master bibliographic records in WorldCat will be
evaluated on a to-be-determined schedule and as capacity allows. 

OCLC has begun processing records selected from among new and replaced
records and will gradually increase the number of records processed each day
over the next few weeks. We will announce when we begin processing existing
records and will report periodically on progress.

Criteria for record selection. The software will select candidate
bibliographic records for processing that contain the following:

·         An 040 field with no ‡b present and at least one of the following
controllable fields:

*	100, 110, 111, 130 
*	600, 610, 611, 630, 650, 651, second indicator 0 
*	655, second indicator 7, ‡2 lcgft  
*	700, 710, 711, 730 
*	800, 810, 811, 830

·         An 040 field with ‡b present containing the value eng and at least
one of the following controllable fields:

*	100, 110, 111, 130 
*	600, 610, 611, 630, 650, 651, second indicator 0 
*	655, second indicator 7, ‡2 lcgft  
*	700, 710, 711, 730 
*	800, 810, 811, 830

·         An 040 field with ‡b present but containing a value not equal to
eng and at least one of the following controllable fields:

*	600, 610, 611, 630, 650, 651, second indicator 0 
*	655, second indicator 7, ‡2 lcgft  

·         A partially or fully controlled heading.

How the software works. 

The software will not:

·         Attempt to control unqualified personal names (personal name only
that does not include ‡b, ‡c, ‡d, and/or ‡q).

·         Control a heading to an undifferentiated authority record.

·         Cause automated tag flips of any type.

The software will: 

·         Automatically expand dates for candidate personal name headings.

·         Partially control series fields and automatically append ‡v.

·         Control linked non-Latin script headings for candidate personal
name headings.

The software will also make the following adjustments as needed:

·         Apply any appropriate punctuation changes.

·         Attempt to control partially controlled headings.

·         Uncontrol descriptive heading fields (1XX, 7XX and 8XX) if the
value in field 040 in the bibliographic record is not equal to eng.

·         Delete a geographic subdivision from a subject heading if the
heading can be completely controlled and no element of the heading can be
subdivided geographically.

The symbol “OCLCO” will be appended in ‡d of the 040 field in bibliographic
records that are modified by the software.

If a bibliographic record is locked, the software will skip it and
reevaluate it when the lock has been removed.

The new software supplements individual cataloging activity. As with the
“Control All” headings function in Connexion, some circumstances prevent the
software from controlling all headings in WorldCat records. The software
cannot do the manual “Single Control” headings functions that catalogers can
do in Connexion. The software cannot control non-qualified personal names,
headings that have no exact match or that match only partially, headings
that are mis-tagged, headings that contain typographical errors or other
errors that require correction. 

OCLC encourages catalogers working in WorldCat to continue using the control
headings functions in Connexion when adding or upgrading records as you
continue to share your cataloging expertise with the cooperative.
