Title: Persian keyboarding in shared bibliographic records: cataloger-centric vs. user-centric


1
Persian keyboarding in shared bibliographic
records cataloger-centric vs. user-centric
  • William J. Kopycki
  • Middle East Studies Bibliographer
  • University of Pennsylvania Libraries
  • kopycki_at_pobox.upenn.edu

Major libraries contributing Persian-script
records
  • Library of Congress
  • New York Public Library
  • New York University
  • University of California at Santa Barbara
  • University of Michigan
  • University of Pennsylvania
  • Yale University

4
Persian keyboard layout (Windows)
5
Additional characters vs. Arabic
  • ? hex 0686
  • ? hex 067E
  • ? hex 06AF
  • ? hex 0698
  • ? hex 06C0

Just because it looks like a duck
  • Modified Arabic letters in the Persian keyboard

Character Isol Fin Med Init
Hex 0643 Arabic Letter Kaf (Arabic Kaf) ? ?? ??? ??
Hex 06A9 Arabic Letter Keheh (Persian Kaf) ? ?? ??? ??

Experiment 1a
  • Farsi as keyword search with Arabic ya
  • ?????

8
Experiment 1a results
9
Experiment 1b
  • Farsi as keyword search with Persian yah
    (from MS Farsi keyboard)
  • ?????

10
Experiment 1b results
11
Experiment 1b analysis
12
The harsh realities
  • The Persian Ya does not exist in the MARC-8
    Character repertoire, therefore users should not
    expect to realistically achieve results unless
    they switch to the Arabic Alif Maksurah.

13
Experiment 1c
  • Farsi as keyword search with Arabic Alif
    maksurah
  • ?????

14
Experiment 1c results
15
Variation on this experiment
  • (In LC Catalog, set limits to retrieve records
    encoded as Persian only)
  • 32 records using ?????
  • 618 records using ?????

16
However in WorldCat
  • ?????
  • ?????

17
Normalization in WorldCat
18
Experiment 2a
  • Search LC catalog for Kishvar using Arabic
    kaf
  • ????

19
Experiment 2a results
20
Experiment 2b
  • Search LC catalog for Kishvar using Persian
    kaf
  • ????

21
Experiment 2b results
22
Meanwhile, back in WorldCat
  • ????
  • ???? (?????)

23
Finally, a word about Nim Fasalah
  • Nim Fasalah
  • ZWNJ symbol in Unicode
  • hex 022C
  • numlock Alt0157 keypad

24
Nim Fasalah makes things look nice and retrievable
  • This
  • ????????
  • NOT
  • ???? ???

25
Else
26
Experiment 4a
  • In LC catalog
  • ????????

27
Experiment 4a results
28
Experiment 4b
  • In LC catalog, using space (w/quotes)
  • ???? ???

29
Experiment 4b results
30
The WorldCat perspective
  • 93 records when using ????????

31
The WorldCat perspective
  • 138 results when using ???? ???

32
The Numbers game
  • Compare the following
  • hex 0660 - 0669 vs. hex 06F0 - 06F9
  • The Persian forms of the numbers 4, 5 and 6 are
    not currently available for use in cataloging

33
Recommendations
  1. Create agreed-upon standards for input
    conventions of Persian script in shared
    bibliographic records.
  2. Replace/update existing records to reflect these
    conventions.
  3. Explore feasibility making additional UTF-8
    characters valid for input.
  4. Explore reasons behind current normalization in
    WorldCat, in automated systems.

34
Recommendations
  • 5. Work to create documentation to education
    patrons on how to best retrieve Persian-script
    records in OPACs and WorldCat.
