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, reissue 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 task group members
Karen Anderson, Backstage Library Works
Robert Bremer, OCLC
Ana Cristan, Library of Congress
Paul Frank, Library of Congress
Richard Moore, British Library
Gary L. Strawn, Northwestern University
David Williamson, Library of Congress
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

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

Phase 3: Changed relator terms
• One-for-one exchanges
editor of compilation
becomes editor
adapted 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 results
Generation of 046 fields
• Cleanup
Add death date to headings
Communication
• Documents in preparation
• Facebook and Twitter
• RDA and PCC lists
That’s all for now!
