  1. The DDC at Universitätsbibliothek Wien Universitätsbibliothek Wien 29 April 2009 Joan S. Mitchell Editor in Chief, DDC OCLC mitchelj@oclc.org

  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

  6. WorldCat

  10. 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

  11. Dewey Community • ACOC National Libraries • ALA Translation Teams • CILIP Research Partners • EDUG HILT (UK) • Konsortium DDC Deutsch DNB • NKKI JRC (EC) • SABINET CACAO (EC) • Editorial Policy Committee • LC & OCLC • DDC Editors • Dewey Users around the World

  12. Language-independent representation

  14. Mappings to subject headings (1) • Library of Congress Subject Headings (LCSH) • Medical Subject Headings (MeSH) • Canadian Subject Headings (CSH) • Sears List of Subject Headings (Sears) • Book Industry Standards and Communications (BISAC) Subject Headings

  15. Mappings to subject headings (2) • RAMEAU [French] • Schlagwortnormdatei (SWD) [German] • Nuovo Soggettario [Italian] • Sears Lista de Encabezamientos de Materia [Spanish]

  19. Crosswalks between schemes • LCC – DDC (ClassWeb, Classify) • UDC – DDC (IZUM, Czech National Library) • SAB – DDC (Electronic updated version at National Library of Sweden) • But no explicit crosswalks for • RVK-DDC (some experimentation in Carmen) • BK-DDC (???)

  20. Tools using explicit and derived relationships • Classify • VIAF • WorldCat Identities

  21. 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

  29. What are some uses of the DDC? • A few examples that focus on the use of the DDC to enhance browsing and retrieval . . .

  30. Access Numbers: Examples (1) • History of Vienna, Linz, and Salzburg • 082 00 $a 943.6 $2 22 (Austria) • 083 0# $a 943.613 $2 22 (Vienna) • 083 0# $a 943.624 $2 22 (Linz) • 083 0# $a 943.632 $2 22 (Salzburg)

  31. Access Numbers: Examples (2) • Geographic access in the British Library Newspaper Project: • Birmingham Post • 083 0# $z 2 $a 424 $2 22 $q Uk (West Midlands) • 083 0# $z 2 $a 42496 $2 22 $q Uk (Birmingham City)

  40. Training: Resources • Einleitung in die Dewey-Dezimalklassification • http://www.ddc-deutsch.de/publikationen/pdf/DDC_22_Deutsch_Einleitung.pdf • Glossar • http://www.ddc-deutsch.de/publikationen/pdf/DDC_22_Deutsch_Glossar.pdf • Dewey-Dezimalklassification: Theorie und Praxis (Chan & Mitchell) • Dewey Training Site • http://www.oclc.org/dewey/resources/teachingsite/200801/default.htm • Application practice by key users in WorldCat, e.g., LC, BL, DNB

  41. 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?
