2. 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?

3. 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

4. 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

5. 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
