In linguistic papers on language change it is often stated that the Russian language since the 1990s has adapted to the new political, economical and social conditions by reacting in varied ways to the changes of the so-called extralinguistic environment. Linguists, however, usually concentrate on the description of phonetical/phonological, morphological, lexical or syntactic changes without paying attention to changes of text types. In the present article, by the example of a study of scientific texts I investigate the process of the democratization of written academic speech from the 1950s up to now. For this purpose, I concentrate on different linguistic means of expressing personalization. As a basis for my diachronic empirical investigation serves a homogeneous corpus of written texts of the type ‘academic article’ in well-known linguistic journals.
