For some months now, OCLC's WorldCat Quality Management Division has been
planning and implementing a project to incorporate "Resource Description and
Access" (RDA) practices, references, and examples into OCLC's "Bibliographic
Formats and Standards" (BFAS) (http://www.oclc.org/bibformats/en.html).
OCLC's recent migration to a new content management system has now allowed
this effort to begin.

 

We are now in the process of incorporating the changes to BFAS that were
part of the OCLC-MARC Update 2012, which was documented in Technical
Bulletin 261
(http://www.oclc.org/support/services/worldcat/documentation/tb/261.en.html)
.  We are also taking this opportunity to announce the implementation of the
OCLC-MARC Update 2013, which is documented in the new Technical Bulletin 262
(http://www.oclc.org/support/services/worldcat/documentation/tb/262.en.html)
.  Highlights are listed below.  The changes resulting from this OCLC-MARC
Update 2013 are also being incorporated into BFAS.  The updates to BFAS
resulting from these two sets of changes have now begun and will continue
through coming weeks.

 

As part of these changes, the PDF version of BFAS has been discontinued.
There are two main reasons for this decision: 

1)  The PDFs had extremely low usage rates.  As an example, the most heavily
used PDF covered the 0XX fields and was accessed 3 times per day on average
from February 2008 to February 2013.  In contrast, the 0XX HTML files were
accessed 1,323 times per day on average over the same five-year period.

2)  The maintenance of two formats exerted a significant drag on the speed
with which updates could be made.

As a result, we anticipate more timely updates and corrections from now on.

 

When we finish the task of incorporating the changes from the 2012 and 2013
OCLC-MARC Updates into BFAS, we will begin the larger job of reviewing BFAS
in its entirety.  Policies will be updated, links to "Searching WorldCat
Indexes"
(http://www.oclc.org/support/services/worldcat/documentation/searching/searc
hworldcatindexes.en.html) will be added, occasional references to RDA and
the Library of Congress-Program for Cooperative Cataloging Policy Statements
(LC-PCC PSs) will be incorporated, and some examples will be updated and
others added to reflect RDA practices.  This is a huge undertaking and will
be happening gradually over time.  

 

In the meantime, we have brought together on the OCLC "About RDA" page
(http://www.oclc.org/rda/about.en.html) links to LC, OCLC, and other
documentation about RDA.  These include the current "OCLC RDA Policy
Statement" (http://www.oclc.org/rda/new-policy.en.html) and a recorded
Webinar that takes an in-depth look at that policy statement
(http://www.oclc.org/worldwide/en_us/events/2013/rdawebinar04-1713.html).
Many cataloging communities (including AV, music, maps, etc.) are working on
their own RDA "best practices" documents and we will be providing links to
those as they become available.

 

In short, we have begun our work to bring BFAS into the world of RDA.  You
will be seeing changes regularly as the BFAS Update Project progresses.

OCLC-MARC Bibliographic, Authority, and Holdings Formats Update 2013

OCLC has now implemented the changes related to the OCLC-MARC Bibliographic,
Authority, and Holdings Formats Update 2013, which are detailed in OCLC
Technical Bulletin 262
(http://www.oclc.org/support/services/worldcat/documentation/tb/262.en.html)
, now available.  This installation includes MARC 21 Update No. 15 (dated
September 2012), code list additions and changes published chiefly since May
2012, and other suggestions from WorldCat users and OCLC staff.  Many of
these elements, including those from MARC 21 Update No. 15, are related to
Resource Description and Access (RDA).  Among the points of interest:

.                 In Bibliographic Scores 008/20 and 006/03 (FMus), existing
codes "c" (Accompaniment reduced for keyboard), "d" (Voice score with
accompaniment), and "h" (Chorus score) have been "redescribed" and a new
code "k" for "Vocal score" has been defined.

.                 In Bibliographic field 024, both old-style (ten-character)
ISMNs and new style (thirteen-character) ISMNs may now be input and coded
correctly.

.                 In Bibliographic field 028, new subfield $q for
"Qualifying information" has been validated.

.                 Bibliographic fields 261 (Imprint Statement for Films
(Pre-AACR1 Revised)) have been converted to field 260 and are no longer
valid for input.

.                 Bibliographic fields 262 (Imprint Statement for Sound
Recordings (Pre-AACR2)) have been converted to field 260, to the extent that
was safely possible.  Field 262 is no longer valid for input.  Due to
incorrectly coded or contradictory data, many 262 fields remain unconverted.
Any unconverted or incorrectly converted 262 fields should be corrected when
possible or reported to OCLC via [email protected].

.                 In Bibliographic field 511, long-obsolete First Indicators
blank, 2, and 3 have been converted and invalidated.

.                 New Bibliographic and Holdings fields 883 for
"Machine-Generated Metadata Provenance" have been validated, but are
intended for future use.  Please do not use field 883 at this time.

.                 Authority field 368 (Other Attributes of Person or
Corporate Body) has been renamed; existing subfield $c (Other designation)
has been redefined; and new subfields $d (Title of person), $s (Start
period), $t (End period), $u (Uniform Resource Identifier), and $v (Source
of information) have been validated.  NACO participants should not input
these new subfields in the Authority 368 field until an announcement
regarding their use is made by the Program for Cooperative Cataloging.

.                 New indexes will be implemented at a future date,
including several involving Dewey Decimal Classification data in
Bibliographic fields 082, 083, and 085; several to account for
recently-implemented subfields in Bibliographic field 502 (Dissertation
Note); and an Action Note Authorization index for both Bibliographic and
Holdings fields 583 subfield $f.  There will also be some additions to
various existing indexes.  OCLC will announce availability via logon
Messages of the Day, Connexion News, and the OCLC-CAT discussion list.
