The aim of the project CrissCross was to improve and facilitate accessibility to heterogeneously indexed documents for library users searching in library catalogs, with simultaneous consideration of modern search methods. In order to achieve this, the topical headings of the German Subject Headings Authority File (SWD) were mapped to notations of the Dewey Decimal Classification (DDC), i.e., its German version DDC Deutsch. In addition equivalences of the controlled indexing vocabularies SWD, LCSH (Library of Congress Subject Headings), and RAMEAU (Répertoire d'autorité-matière encyclopédique et alphabétique unifié) were established, based on the approaches of the MACS project. The result is a thesaurus-based and user-friendly research vocabulary ideally suited for further research especially in the context of the semantic web. The projects' output is published as linked data and may be used free of charge.
