This chapter inquiries into the author as a subject as a means to study the ideologies behind textbook creation and the struggles faced when designing textbooks. My study aims to unveil the coloniality present during the process of creating, developing, and adapting material, which is still used as a core resource for language learning and teaching in the Colombian context by authors and editors, who play the leading role in the process. The chapter has three sections: the first section is autobiographical and includes my positionality statement; the second describes my research interest on a general level; and the third section addresses the salient elements of the research focus of my research interest. This helps me to root my interest in setting out the author within the textbook creation process.
