The article analyzes research on comics and the formation of readers, reviewing the concomitances and intersections between comics and the didactics of children's and youth literature. The main problems that research on comics faces are examined, such as the complexity of its definition and its epistemological location. Although there has been an increase in research on comics, it still faces challenges in its academic consideration and its presence in libraries and classrooms. The text addresses the lack of a solid and rigorous academic discourse in research on comics, as well as the difficulty in defining its identity and location in the field of children's and youth literature. The concern for the exposure of complex themes in comics aimed at children and young people is also highlighted, as well as the restrictive conception of childhood as the exclusive recipient of this type of work. In addition, the history of marginalization and denial of children's literature and comics is mentioned. The article analyzes the evolution of comics as a literary genre and its consideration as an object of study. The break in the identification of comics with the child audience and the incorporation of the adult perspective in works published during the 1950s and 1960s is highlighted. The marginalization and lack of legitimacy of comics, as well as the prejudices and stereotypes associated with their reading, are also addressed. However, the change in its consideration in Spain is highlighted, with greater attention in the media, the creation of awards, and its presence in libraries and bookstores. The article analyzes the growth of the comic market aimed at adults in Spain, highlighting the year 2007 as a milestone with the publication of works such as "María y yo" by Miguel Gallardo and "Arrugas" by Paco Roca. These works marked a change in Spanish comics towards social and political themes. However, the use of the term "graphic novel" has generated controversy, with two main perspectives: the culturalist, which sees comics as an artistic expression, and the integrative, which considers the appeal to "graphic novel" unnecessary to legitimize its cultural value. The article also addresses prejudices about comics and their impact on the formation of readers, highlighting their role in shaping the imagination of generations of children and adolescents. It is argued that comics do not imply a lower reading competence and that their inclusion in the classroom can contribute to the integral development of students. The importance of mediator training and the need for an artistic canon of comics to bring quality titles to the classroom are highlighted. In conclusion, comics offer opportunities for the formation of competent readers and the renewal of the school canon. The article discusses the lack of inclusion of comics in education and the educational curriculum, despite its pedagogical advantages. The lack of knowledge about quality titles and prejudices can lead to the exclusion of comics in the academic and classroom environment, which implies the loss of an aesthetic and pleasurable reading experience for students.
