- Abstract
- The ETH library has been using the UDC for the past twenty-five years and yet most of the users had almost never taken a single notice about it. The query in today's NEBIS-OPAC (former ETHICS) is based on verbal search with three-lingual descriptors and corresponding related search-terms including e.g. synonyma as well as user-friendly expressions from scientific journals - scientific jargon - to facilitate the dialog with OPAC. A single UDC number, standing behind these descriptors, connects them to the related document-titles, regardless of language. Thus the user actually works with the UDC, without realizing it. This paper describes the experience with this OPAC and the work behind it.
