Two PCC task groups

Original: PCC Task Group on AACR2 & RDA Acceptable HeadingsWhat can be done to prepare LC/NACO Authority File for RDA?

Current: PCC Acceptable Headings Implementation Task GroupMake 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 documentsWrote test programSolicited commentsNot as much participation as I would

have liked

Notable things people didn't like

Some records issued twiceToo 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 records-to-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) conferencesSubfield $l has "Polyglot" or "&"TreatiesLibrettos and texts

Mechanical changes?

Replace b./d. in X00 $d with hyphenReplace music abbreviationsRemove testament from "Bible"

headingsReplace "Koran" with "Qu'ran"Parentheses in X00 subfield $cAdjust date subfields ($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 programWill be run at LCChange 30,000 records per day5 days per weekWeekly 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 givenCompletion: 3-4 weeks after start

Phase 2Begins March 1, 2013Finish coincides with Day 1

RDA 7XX handled between phases 1 and 2

List produced by conversion programList posted for use by interested

partiesRDA 7XX only interesting if different

from non-RDA 1XXReview is entirely operator-based; no

programmatic changes

Cleanup after phase 2 (sample)

'Dept.' not expanded‘arr.’ not expandedUnexpected abbreviation in X00 $dCould not create 046

Conditions may change

Definition of acceptable texts for X00 $c

Disposition of 'Apocrypha'Conversion program written to allow

be issued
