The article substantiates the principles of studying the graphic content of Dostoevsky᾽s handwritten texts and creating an electronic catalog of graphic samples that would include the most representative examples of the writer᾽s handwriting and their scientific description. The research material is Dostoevsky᾽s workbooks, which include entries of various kinds: rough sketches for artistic and journalistic ideas, letter drafts, notes for memory, addresses, calculations related to household and editorial and publishing . The variety of the material under study allows us to collect more informative and complete data on the specifics of graphic characteristics in the writer᾽s texts. The analysis and systematization of handwriting features, typical and atypical handwriting, are productive in deciphering the so-called “difficult readings” and are important for understanding the semantic context of Dostoevsky᾽s recordings, in some cases allowing to clarify important factual information. The practical value of the research lies in the possibility of using the data obtained in the study of hard-to-read handwriting, illegible spellings, as well as in the analysis of non-verbal forms of Dostoevsky᾽s graphics and their role in the creative process of the author. To solve these problems, a special toolkit has been developed that allows for the research selection of graphic images and their description.
