Тhe beginnings of a bilingual Russian-Polish and Polish-Russian lexicography: A literature review The article presents an attempt to consolidate data of Russian-Polish and Polish-Russian lexicography of the period from the 17th century to the first quarter of the 19th century, provided in the bibliography of Polish dictionaries compiled by P. Grzegorczyk and the works of archeographists and historians of written languages. The author supposes that the absence of earliest Polish-East Slavic and East Slavic-Polish dictionaries in the most complete bibliography of Polish dictionaries may be explained as a consequence of the ambiguous ethnic character of written languages of the East Slavic peoples compared to recent differenctiation of East Slavic languages, as well as a result of the manuscript character of those dictionaries.
