Celebrating 20 years of machine-proposed
authority records
2
Getting ready for RDA

• RDA brings many changes
• Some differences might be accommodated by program
• PCC Acceptable Headings TF

3
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

4
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
  "

5
Phase 1 criteria

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

6
Phase 2 outline

• Records susceptible to some mechanical change
• Some also marked with 667 field some re-coded as
  RDA

7
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

8
Both phases secondary changes

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

9
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"

10
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

11
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?

12
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

13
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

14
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

15
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

16
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

17
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

18
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.

19
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

20
Expanded 046 example

• 1001 a Hatto, A. T. q (Arthur Thomas)
• 670 a Times online WWW site, Mar. 19, 2010
  b (Professor Arthur Hatto b. Arthur Thomas
  Hatto, Feb. 11, 1910, London d. Jan. 6, 2010)
• 046 f 19100211 g 20100106

21
Expanded 046 example

• 1001 a Shimizu, Ryojin, d 1920-
• 670 a Chosakuken daicho, 1985 b (Shimizu
  Ryojin real forename Yoshinobu b.
  11/27/Taisho 9)
• 046 f 19201127

22
Expanded 046 additional use 1

• 1001 a Kaser, Max, d 1906-
• 670 a VIAF, searched Feb. 21, 2014 b (DNB
  access point Kaser, Max, 1906-1997)
• 046 f 1906 g 1997

23
Expanded 046 additional use 2

• 046 f 18121223 g 19041104
• 670 a Wikipedia, May 13, 2014 b ( died 13
  November 1904)
• Calculated death date 19041113

24
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

25
Phase 3 ISNI

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

26
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

27
Phase 3 schedule

• Final report by March 15, 2015
• Report will propose timetable for doing the work
• Final decision to be made by PCC

28
Community involvement

• Testing Review of results
• Generation of 046 fields
• Cleanup
• Add death date to headings

29
Communication

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

30
Thats all for now!
