This contribution is part of my thesis, which follows up on the thesis Starting points for a new physics curriculum (by Petr Kolář). The aim of the thesis is to pilot a new physics textbook for upper secondary schools, which is being created at the Department of Physics Education, MFF UK.
Currently the search of international literature is in progress. I describe the process of the search focused on science textbooks analysis and I mention methodology that was used in selected studies in this area.
