Complex KO Environment at UW
•Accession date scheme used for shelving
•GND authority file (PND, GKD, SWD)
•Two classification schemes:
• Basisklassifikation (BK) to be added in June 2009
• DDC to be introduced by 2014
What is the potential role of the DDC in this complex Knowledge Organization (KO) environment?
Outline
• What are the benefits of the DDC?
• What explicit and implicit relationships exist between the DDC and other KO tools?
• What are some uses of the DDC?
• What resources exist for DDC training?
• Discussion
What are the benefits of the DDC?
•Large amount of categorized content
•Organizational support
•Worldwide user community
•Language-independent representation
• Interoperable translations
•Mappings and crosswalks
DDC already associated with a large number of resources
• WorldCat
• ~25% of WorldCat records include explicit Dewey numbers plus more derived using FRBR work sets
• Number is growing, e.g., Deutsche Nationalbibliothek is now adding Dewey numbers to WorldCat nearly at the same rate as the Library of Congress
• Other utilities and databases, e.g., BIBSYS, NORART, NORBOK
• Digital libraries, e.g., World Digital Library
Organizational support
• Permanent editorial staff at LC and OCLC
• OCLC research and development teams
• Ten-member international advisory board (EPC):
• Current members from Australia, Canada, South Africa, UK, US
• National libraries and translation teams with observer status

Classify
•DDC/LCC/NLM classifier
•Developed by OCLC Office of Research
•Based on FRBR cluster data
•Work-set summary of class numbers assigned
•Human interface + web service

Discussion
How will you associate Dewey numbers with existing bibliographic records?
What kinds of materials will be classified by Dewey?
Will you contribute standard numbers to WorldCat?
Do you plan to assign access numbers as well as standard numbers?
