An open, extendible multi-dictionary system is introduced in the paper. It supports the translator in accessing adequate entries of various bi- and monolingual dictionaries and translation examples from parallel corpora. Simultaneously an unlimited number of dictionaries can be held open, thus by a single interrogation step, all the dictionaries (translations, explanations, synonyms, etc.) can be surveyed. The implemented system (called MoBiDic) knows morphological rules of the dictionaries' languages. .
