ENThe article presents a manuscript collection of dialect lexicon from the 2nd half of the 19th century compiled by Artur Doliński. The glossary records the vocabulary characteristic of the folk dialect of the Vilnius area. The author has established that in terms of methodology, Doliński’s work differs from other studies of this type (the entries are not arranged alphabetically, they lack qualifiers or explicataions of how to use a particular word). However, this does not diminish the value of the work under discussion, since the glossary records unknown lexemes from historical Lithuania, and attests to phonetic and grammatical features inherent in the borderland variety of the language. This makes Doliński’s work an important source for the study of Polish dialects in the 19th century Northeastern Borderlands. Key words: dialect dictionaries of the 2nd half of the 19th century, borderland Polish, folk dialects. [From the publication]
