CrissCross – Overview


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 LibraryCologne University of Applied Sciences

Financially supported by:German Research Foundation

CrissCross – 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, …)
