CrissCross Overview

• Insights and Outlooks A Retrospective View on
  the CrissCross Project

• Aim
• creation of a thesaurus-based, user-friendly
  research vocabulary that facilitates search in
  heterogeneously indexed collections by mapping
  topical headings of the German subject headings
  authority file Schlagwortnormdatei (SWD) and the
  Dewey Decimal Classification (DDC)
• Duration 2006 2010
• Conducted by German National Library Cologne
  University of Applied Sciences
• Financially supported by German Research
  Foundation

CrissCross DDC

• Insights and Outlooks A Retrospective View on
  the CrissCross Project

Dewey Decimal Classification (DDC)

• most widely used universal classification system
• used by 200,000 libraries in over 135 countries
• translated into more than 30 languages
• since 2006 used by the German National Library
  (DNB) for subject indexing
• contains about 50,000 classes
• structured by disciplines (e.g. religion, social
  sciences, technology, )
