One of the perspectives of research on the history of evaluation of ethnological works is to analyse reviews of ethnological and ethnographic works. We have chosen Antanas Mažiulis (1914–2007), who wrote many reviews of works in Lithuanistic studies. The aim of the article is to reveal how Mažiulis understood, appreciated and critically approached the science of ethnology. Since his reviews covered a wide range of topics and issues, we will concentrate only on the analysis of terms and methodological issues in them.
