Record counts
Intended primarily to give a notion of
scale
Not intended to be definitive
Counts will change as specifications

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
