The thesis consists of an empirically based qualitative content analysis of four Swedish reading promotion program reports of concluded and evaluated public library run reading promotion programs aimed at children and young adults. The empirical material was confronted with research findings in reading promotion activities. While there is plenty of research concerning reading motivation, there is less research available to understand how this crucial reading motivational work for children is conducted by public libraries and which research-based reading promotion methods the government-funded projects are based on. Considering also the fact that reading promotion activities for children are sustained and regulated by Swedish law. The scope of this thesis is to seek to elucidate those research-based reading promotion activities that have proved helpful to children and young adults´ reading enjoyment and intrinsic reading motivation and also suggest areas where improvements can be made in the interest of children and young adults. Thus, special attention is given to a child-centered perspective in the analysis of the reading promotion projects. The child-centered perspective being especially relevant today as on January 1st, 2020 the United Nations Convention on the Rights of the Child Act became law in Sweden. Findings confirmed expectations that the reading promotion programs were, indeed, for the greater part, research-based. As for the child-centered perspective there is still more work, and research, to be done in order to integrate the literacies of last year with current literacies. Hopefully, the findings of this thesis will aid the librarian in planning reading promotion activities for children and young adults supported by scientifically based research.
