 After the restoration of independence of Lithuania, Bučys wrote the first essay on the history of Lithuanian literature, where emigration literature is presented as an organic part of a single national literature.After twenty "years of silence" (from book about Lithuanian novelist Jonas Avyžius in 1990), Bučys issued (since 2008) three literary studies that emerged new methodological and cultural concepts.Many years of close acquaintance with the writers of different nations and the works of various national literatures inevitably led to the need to find and develop new methods of studying the peculiarities of each national literature.
