This master´s thesis is a qualitative study that examines reader leaders’ experiences of Shared Reading with children and young people aged 11-17 years. Ten reader leaders were interviewed about their arguments to work with Shared Reading with children and teenagers and whether they feel that Shared Reading contributes to increased engagement in reading among the young people they have met. The study also examines what motives the reader leaders have for working with Shared Reading in schools and if they see any problems or difficulties when working with Shared Reading in schools. To shed light on the work with Shared Reading in libraries and schools, the theory of practice architectures has been used. I conducted a qualitative interview study with ten informants. The qualitative results were analysed with content analysis.The results shows that the informants emphasize that reading aloud makes the texts accessible, even to those who are inexperienced or unwilling to read. The informants states that it gives participants a feeling of being accepted regardless of previous experiences of reading. The social context is an important part of Shared Reading. The informants appreciate the joint meaning-making and that the participants help each other to understand a text. The fact that everyone's voices are important in the group is inclusive, and to do things together in a group promotes reading engagement. Shared Reading is a method that promotes reading, but joint reading also promotes the participants' personal development and group relationships. Informants emphasize that the young participants see that people's differences and different opinions are good, and that they practice arguing and accepting the participants' different opinions. Thus, Shared Reading can promote the group's relationships and be a way of working for democratic values. Furthermore, this study shows many benefits for libraries to collaborate with schools through Shared Reading. In outreach work towards the school, Shared Reading reaches more children than those who come to the public library. By collaborating with the school and teachers, the opportunity to be more adults around reading sessions with Shared Reading increases. Informants have also experienced that young people are not used to relating reading to their own lives and that assessment affects students' relationship to text conversations and reading. Shared Reading can be a complement to the school's reading, which is more focused on an analytical reading of text and evaluative reading comprehension. Shared Reading can serve as a space free from assessment and a performance-oriented culture in schools.When young people see themselves as competent readers, it can motivate further reading. Sharing thoughts and discussing texts together with others motivates children and young people to participate in the joint reading. Informants see that the democratic and inclusive values that Shared Reading stands for can be motivating and engaging. Based on the results of this study, Shared Reading removes the barriers to reading and opens paths for literature to strengthen readers' self-confidence and reader identity. Shared Reading in libraries and schools can promote the reading of literature in a way that creates empathy, builds relationships, and is inclusive and democratic.
