background
Background
  • History of CJK records
  • Retrospective Conversion
  • Reclassification
  • Backlog Reduction
history of cjk records
History of CJK records
  • App. 168,000 records using Pinyin with hyphenation have been converted into standard Pinyin
  • App. 70,000 records from RLIN have been converted from Wade-Gile into Pinyin except Tag 1XX,6XX,7XX
  • 79,015 old records’ Single Pinyin Syllable were generated by a program in 1996 but not reaching the current Pinyin standard
  • Fung Ping Shan Library Classification
retrospective conversion
Retrospective Conversion
  • Automatic Conversion again?
  • High Quality Records need human involved
  • Change the major direction from automatic conversion to automatic matching and retrieving
  • Automatic conversion become an assistant only
reclassification
Reclassification
  • From Fung Ping Shan Library Classification to LCC
backlog reduction
Backlog Reduction
  • From brief records to complete cataloged bibliographical records
how can automation help
How can automation help?
  • Use Resources from JULAC members (Academic Libraries in HK)
  • Reasons:
    • Overlapped collection (especially CJK)
    • Similar cataloguing standard/requirement
    • Use the same library system (Innopac)
what is catwork
What is CatWork?
  • A byproduct of the recon & re-class projects
  • A Web version of InnoFace (see HKIUG 2001)
  • Not a machine of automatic cataloguing
  • A cost-effective tool for reducing redundant cataloguing work among libraries
  • TwinsPAC
    • A new design of a user-friendly and two-in-one interface for cataloguers to compare two bibliographic records from two WebOPACs
what is catwork cont d
What is CatWork? (Cont,d)
  • An all-in-one program includes features:
    • XML, UTF-8 & WebOPAC based
    • Cataloguers input Bib record number only for matching
    • Extract the Bib record and backup the MARC record from the source library
    • Convert the Bib record into XML format
    • Match the Bib record to other libraries’ records
    • Download the MARC record in ISO-2709 exchange format from the target library
    • Add Tag 907 with the source record’s bib no. to the target MARC record
    • Overlay the MARC record of the source library with the target MARC record
    • Options: Instant Matching and Batch Matching
practical experiences with catwork
Practical Experiences with CatWork
  • Step 1: 79,015 HKU CJK Bib records were extracted and converted into XML format for matching
  • Step 2: 28,275 CU Bib records were found
  • Step 3: 28,275 CU MARC records were downloaded
  • Step 4: 28,275 HKU MARC records were overlaid by CU MARC records
  • Time: The program’s running time of the above steps was within 48 hours
  • Hit rate: 36%
  • Accuracy: 99.9% (Cataloguer found ONE mismatched record within 1,000 records)
  • Saved Cost: If a staff takes 10 min. to do recon and re-class for one record and the salary is HK$45 per hour, then these 28,275 records could save HK$212,062.50

  • Search Title and Publication Year [http://catalog.lib.washington.edu:1087/search/t{215f6f}{213b65}/t{215f6f}{213b65}/,,,B/frameset&FF=t{215f6f}{213b65};Ya=1989;Yb=2001&,,]
  • Target Record has been catalogued [Includes LC call no. in local tags: 09X]
  • Target Record’s Tag 260 contains Source Record’s Publication Place and Publisher [Use Inclusive matching instead of Exactly Matching]

  • Backup & Download: using XML format from Innopac’s xrecord function instead of ISO-2709 format
    • Simplified the program’s procedures
    • Faster
  • More Linkages
    • E.g. ISBN or Author for reference
  • Add User-defined matching rules: Flexible, Simple and User-friendly
  • Add a Bib record Pre-Editor on the Web for cataloguers to edit before uploading the MARC
thank you for all cataloguers effort
Thank you for all cataloguers’ effort

If there is no cataloguer,

the matching result will be “0”.
