The current state of the cross-regional topic-based survey conducted for the Lexical atlas of Russian folk dialects: the results of 30-year long enterprise
This article summarizes a long stage of quantitative analysis conducted over the materials of the Lexical atlas of Russian folk dialects and initially presented in the year 2019. In this paper we discuss the current research state of all the data collected by 2021, the year when the Atlas project members celebrate the 30<sup>th</sup> anniversary of their fieldwork activities. Our work exhaustively draws upon the Project's paper and digital databases. Over the years the means of data sorting, digitizing and storage have considerably changed, which gave us an opportunity to provide each project member with a preferential fieldwork sphere, including such topics as “Nature”, “Human Being”, “Labor Activity” and “Material Culture”. Each table comprises a single geographical area and includes all its examined districts with their respective numbers.
