CrissCross – Overview
Cologne, 19th July 2010
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

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
