The article substantiates a new object of quantitative historical-psychological research - publications in a certain scientific direction. The authors refer to the study of the scientific direction of methodology of psychology in the publications of the Institute of Psychology of the Russian Academy of Sciences for 2002-2021. The criteria for selecting research material (publications and their content for creating a text corpus) are described, indicators of bibliometric and scientometric analysis are listed, and procedures for determining separate indicators of analysis of a text corpus of publications are considered. The results of a quantitative analysis of the publications of the Institute of Psychology on the methodology of psychology (a total of 18 books - author's and collective monographs, collections of articles) are presented for five-year periods (2002-2006, 2007-2011, 2012-2016, 2017-2021), the following indicators are demonstrated: the distribution of the number and the volume of publications, the frequency of new and recurring authors, the share of authorship of the Institute's employees, the frequency of words for the entire study period and the key phrases of text corpora by five years, the number of citations of each publication and groups of publications by period, articles with the largest number of citations, the share of citations of publications by methodology psychology among the citations of all editions of the Institute of Psychology. It is concluded that methodological issues are significant for the research activities of the staff of the Institute of Psychology, but a narrow circle of researchers is formed around it (both employees of the Institute and authors from other organizations). The methodological publications discuss the Institute's traditional methodological approaches (complex, systemic, and subjective) and principles (of development), problems of developmental psychology, methodological issues of certain branches of psychology and various applied fields, consider the concepts of prominent scientists who influenced the theoretical and methodological developments of the Institute (B G. Ananiev, S.L. Rubinshtein) and those who directly formed methodological issues at the Institute (A.V. Brushlinsky, B.F. Lomov, K. K. Platonov, Ya.A. Ponomarev).
