The article discusses mediostructures in bilingual Polish-German and German-Polish LSP dictionaries. The first part presents the structure of dictionary references and two types of mediostructures, namely, internal and external, which stems from the intertextuality of the dictionary. Then, on the example of selected entry articles, means functioning as the internal and the external mediostructure were examined, i.e. graphic symbols, abbreviations and references to sources in two bilingual dictionaries. The study shows that the presented dictionaries have different reference systems and thus offer the user unequal information on the level of other structures of the dictionary, that is, the micro- and the macrostructure.
