This article discusses changes in the materiality of textbooks by examining several examples of primarily Slovene textbooks from various periods. By focusing on their spread design rather than technical aspects (e.g., length, weight, and format), one may infer that their materiality changed with the development of printing technologies and publishing skills. Based on the assumption that textbook visuality is a field of meaning that requires different bodily movements, postures, and engagement with the physical environment to produce cognitive processing, this article sheds light on how the body adapts to the changed materiality of digital textbooks. Numerous micro-movements in a long string of procedures are required in a digital textbook ecosystem. All the participants should be aware of the different demands and properties of the digital textbook ecosystem. Therefore, further empirical research is needed.
