The author substantiates the application of transdisciplinary approach to the book typology studies. While emphasizing the relevancy of these studies, she reviews the theoretical aspects of the book definition and typological features as they appear in the article by Yury V. Nesterovich “Reviewing the “book” term explication in the context of documentology”. The analysis makes the author convinced that the book typological characteristics have to be seen as the theoretical foundation for grouping the information objects of the book type rather than as the basis for classifying the items within this type structure. In this context, the “book’ term has to be formulated from metatheoretical perspective, along with the documentological and categorical approaches, and adopted to the present information space. Such analysis enables to study the book as a complex fuzzy system and to look at the book typology from the perspective of fuzzy logics theory The author emphasizes transdisciplinary character of these studies and cites some results of fuzzy logic application to e-book analysis. She concludes on the good perspectives for transdisciplinary strategies in the book typology studies.
