The paper addresses the issue of using the content of the Polish language textbooks for lower secondary school students in studies on socio-cultural identity. It presents the circumstances leading to raising the topic: the relationship of the educational process with identity formation, the youth development phase, the specific content of these textbooks and the political context that is put forth. Then, an analysis of parts of the textbook by W. Bobiński Świat w słowach i obrazach (The world in words and images), particularly, information about the authors of texts contained in the textbook is undertaken. This reveals selected elements of Polish socio-cultural identity, including the age of the authors, the way of description, the readers exposure to individual authors and the occurring patterns of learning behaviour.
