This article presents three books written by the teachers of Polish/Polish scholars from Vilnius (Lithuania) to the Polish language of Vilnius and Vilnius Region: by Irena Masojc entitled 'Regionalne cechy systemu gramatycznego wspólczesnej polszczyzny kulturalnej na Wilenszczyznie' (Regional Features of the Grammatical System of the Cultural Modern Polish Language in the Vilnius Region); by Kinga Geben entitled 'Swiadomosc i kompetencja jezykowa a warstwy leksykalne w idiolektach mlodziezy polskiego pochodzenia na Wilenszczyznie' (Awareness and Linguistic Abilities and the Lexical Layers in Idiolects Spoken by the Young People of the Polish Origin in the Vilnius Region); and by Miroslaw Dawlewicz entitled 'Slownictwo socjolektu mlodziezy polskiego pochodzenia w Wilnie' (The Vocabulary of the Sociolect of the Young People of the Polish Origin in Vilnius). Irena Masojc's work presents the language spoken by the intelligentsia - the regional variant of the cultural Polish language while the two other works present the language spoken by the Polish young people and the students of universities and colleges. To a great extent the authors owe the successful interpretation of the collected material to their own personal linguistic experience and observations, because they describe the language of their own environment.
