Celebrating 20 years of machine-proposed authority records

Getting ready for RDA

• RDA brings many changes• Some differences might be

accommodated by program• PCC Acceptable Headings TF

Acceptable Headings TF

• Original proposal: do it all at once, re-issue whole file

• Some NACO nodes reluctant• Phased, limited approach; 30,000/day• Phase 1: mark most non-AACR2

records• Phase 2: change records• Possibility of further work left for later

Phase 1 outline

• Find records whose 1XX can not be used under RDA

• Only for records that did not also require a mechanical change to the 1XX

• Add 667: "THIS 1XX FIELD CANNOT BE USED UNDER RDA …"

Phase 1 criteria

• All Pre-AACR2, all AACR2 compatible• Bi-lingual and polyglot $l• Unrecognized 100 $c text

Phase 2 outline

• Records susceptible to some mechanical change

• Some also marked with 667 field; some re-coded as RDA

Phase 2 changes: examples

• Manipulate X00 subfield $d• Parentheses around some X00 $c• Expand 'Dept.', 'acc.', 'arr.', 'unacc.'• Replace 'violoncello'• Bible headings; Koran headings• $t Selections

Both phases: secondary changes

• 046 $f $g from 100 $d• 378 $q from 100 $q• 510 for hierarchical superior

And then?

• Most AACR2 records not touched by Phases 1 and 2

• People expected to know: RDA-OK unless stated otherwise

• March 2014: PCC decides to re-code most remaining records: "Phase 3"

Phase 3: outline

• Re-code most AACR2 records as RDA• At least 7.5 million records affected• Still 30,000 per day?

Will take about a year!

• Issue a new copy of the entire file?Can the NACO nodes deal with this?

Phase 3: Additional stuff

• Re-consideration of X00 $c• Undifferentiated names• Music medium of performance• Changed relator terms• Generation of 046 fields: expanded• Pre-RDA 678 fields• ISNI

Phase 3: Reconsideration of $c

• RDA criteria changed• Lists of acceptable terms greatly

expanded• Some things with 667 will be re-coded

as RDA• British Library very active in this work• $c used to drive generation of 368 $d

Phase 3: Undifferentiated names

• Any coded RDA will be re-coded AACR2

• All will receive the 667• No attempt to split into separate

records by program

Phase 3: Medium of performance

• Working with MLA representatives• Convert 'standard combinations' into

equivalent strings• Generate 382 fields with $2 lcmpt• Probably done as soon as possible• Other 382 fields still under

consideration

Medium of performance examples

• $t Quartets, $m strings$t Quartets, $m violins, viola, cello?? $t Quartets, $m violins (2), viola, cello

• $t … $m … string trio …$t … $m … violin, viola, cello …

Phase 3: 678 fields

• Identify pre-RDA 678 fields• Re-code as 670s$a Information from 678 field, converted

June 16, 2014 $b (…)

• About 2,000 difficult cases already handled one way or another

• Remainder can be handled by program

678s to become 670s

• 15 Sept. death• 1st held 1972• A.A.C.C.A.• AACR 1 & 2: Canada. Bureau for

Translations• Th.D.• Prof.

Phase 3: Expanded 046 generation

• Go beyond 100 $d• Parse 670 fields for useful

information• Fuller birth and death dates• Provision for some non-Gregorian

calendars• Still being tested and developed

Calculated death date: 19041113

Phase 3: Changed relator terms

• One-for-one exchangeseditor of compilation

becomes editoradapted as a motion picture (work)

becomes adapted as motion picture (work)

• Not too many authority records (lots of bibs!)

• Probably done as soon as possible

Phase 3: ISNI

• To be added in 024 field• Decreed to be a priority• Mechanism for maintenance not yet

clear

Phase 3 mechanics

• Same idea as Phases 1 and 2• Program runs against copy of the

LC/NACO file at LC• Program updates records• Output not yet decided

Phase 3 schedule

• Final report by March 15, 2015• Report will propose timetable for

doing the work• Final decision to be made by PCC

Community involvement

• Testing: Review of resultsGeneration of 046 fields

• CleanupAdd death date to headings

Communication

• Documents in preparation• Facebook and Twitter• RDA and PCC lists

That’s all for now!
