The aim of this article is to analyse subject expression evaluation of the non-author language, i.e. the author whose thoughts, discoveries, research results or assumptions are relied on in scientific texts in Lithuanian and English languages, elucidate both universal properties of expression evaluation and the specific ones determined by a particular language and culture. Publication texts of education science field of social science area were selected for the research. Expression evaluation of a quoted author was analysed identifying neutral (surname / name and surname, nationality and residence, scientific and professional activity, time, scientific discoveries, activity achievements, family relations) and subjective (logic and emotional evaluation) attributes. It was determined that education science texts of both languages, Lithuanian and English, do not exhibit a variety of quoted author expression. No examples purveying all possible semantic meanings of attributes were found in both languages. Prevalence of neutral attributes of science subjects and similar aspects of usage of some attributes (surname / name and surname, nationality or residence) reveal general citation traditions determined by universal scientific text regularities rather than a particular language or culture. On the other hand, some tendencies were observed characteristic only to the texts of one or another language and reflecting specific evaluation features of science subject. In the articles of native English speakers, scientific discoveries, results of scientific activity of quoted authors are emphasised whereas Lithuanian authors are more liable to highlight scientific or professional activity and time. Moreover, it is essential to mention that every text represents its author‘s personality to some extent. Thus, the choice of the particular means of expression can be determined by personal qualities of an author.
