Two PCC task groups
Original: PCC Task Group on AACR2 &
RDA Acceptable Headings
What can be done to prepare LC/NACO Authority File for
RDA?
Current: PCC Acceptable Headings
Implementation Task Group
Make this happen
Original implementation scheme
Phase 1: All records that cannot be used
under RDA: mark with 667
Phase 2: Make mechanical changes where
possible; re-code some AACR2 as RDA;
ready for "Day 1"
Phase 3: Re-code remaining acceptable
AACR2 records as RDA (~7,600,000)
Invitation to discussion
Wrote series of detailed documents
Wrote test program
Solicited comments
Not as much participation as I would have
liked
Notable things people didn't like
Some records issued twice
Too many re-issues; no need to re-code
the 7,600,000 acceptable AACR2 records
as RDA (but opinions divided)
As a result of comments
5 alternate scenarios proposed and
discussed
Alternate #3 recommended, approved by
PCC
Revised implementation scheme
Phase 1: mark unchangeable,
unacceptable records (~420,000)
Phase 2: mechanical changes (~350,000)
Later re-coding of the 7,600,000 AACR2
records not contemplated, but not is not
ruled out
Features of revised
implementation scheme
Records only issued once (details on next
slide)
State of record not necessarily explicit
until end of phase 2
Unchanged, acceptable AACR2 records
not recoded
Record state not always explicit
Records with Phase 2 changes are not
issued in Phase 1, so no 667 for recordsto-be-changed
Between Phase 1 and Phase 2, operators
must be especially attentive
On Day 1, things should be clearer
After phase 2, on Day 1:
3 categories
RDA records (including ~300,000 AACR2
re-coded as RDA because otherwise
changed)
Records not suitable for use under RDA
without review; marked with 667 field
AACR2 records suitable for use under RDA
667 text
THIS 1XX FIELD CANNOT BE USED
UNDER RDA UNTIL THIS RECORD HAS
BEEN REVIEWED AND/OR UPDATED
Mark with 667 fields?
Pre-AACR2 records (008/10=a,b)
AACR2-compatible records (008/10=d)
AACR2 records with elements not
compatible with RDA
AACR2, not compatible with
RDA?
100 subfield $c unless defined as
acceptable
(Ongoing) conferences
Subfield $l has "Polyglot" or "&"
Treaties
Librettos and texts
Mechanical changes?
Replace b./d. in X00 $d with hyphen
Replace music abbreviations
Remove testament from "Bible" headings
Replace "Koran" with "Qu'ran"
Parentheses in X00 subfield $c
Adjust date subfields ($d and $f)
Change 'violoncello' to 'cello'
Mechanical changes when record
otherwise re-issued
Any phase: Create 046, 378, 382-384
fields
Any phase: Set undefined indicators to
'blank'
Phase 2: Re-code acceptable AACR2
records as RDA
Phase 2: Remove RDA 7XX fields (see
later)
Performing the work
Conversion program
Will be run at LC
Change 30,000 records per day
5 days per week
Weekly names distribution: ~150,000
more records than usual
Schedule
Phase 1
Begins when testing complete (some time in July 2012)
10 days' notice will be given
Completion: 3-4 weeks after start
Phase 2
Begins March 1, 2013
Finish coincides with Day 1
RDA 7XX handled between
phases 1 and 2
List produced by conversion program
List posted for use by interested parties
RDA 7XX only interesting if different from
non-RDA 1XX
Review is entirely operator-based; no
programmatic changes
Cleanup after phase 2 (sample)
'Dept.' not expanded
‘arr.’ not expanded
Unexpected abbreviation in X00 $d
Could not create 046
Conditions may change
Definition of acceptable texts for X00 $c
Disposition of 'Apocrypha'
Conversion program written to allow for
the possibility
Changes affect number of records to be
issued
Other things will need attention
LCSH authority records
Local authority records
Bibliographic records
