Introduction. The aim of this thesis is to investigate how librarians in public libraries, school libraries and integ-rated libraries relate to reading for pleasure in regards to reading for development in their work with students. A conflict has been shown between promoting voluntary reading and promoting reading ability. We base our re-sults in Qvortrups theory about children as “beings” or “becomings” together with Junckers theory about the distinction between the cultures of the educational sector and the cultural sector. Method. We conducted a qualitative interview study with seven sources from the three library types. We also conducted a quantitative survey study with vignettes taken from the qualitative analysis. Analysis. The qualitative result was analysed with a conventional content analysis. We conducted three inde-pendent one way anovas to investigate if there were any differences between the library types in the survey. Results. The qualitative study showed that all sources highly valued reading for pleasure and the students right to choose literature. The school librarians more often related their work to improving reading ability and to school criteria than librarians from the other two library types. We found similar tendencies in the results from the survey sample but none of these was significant with a significance level of p < 0.05. Conclusion. Librarians from all types of libraries show a reasoning consistent with the view of children as “beings” and the culture from the cultural sector. School librarians in our results do more often than the other two library types show a view of children as “becomings” consistent with the culture from the educational sector. Therefore we would argue that it is important to watch the development with strengthened school lib-raries so that the view of children as “becomings” does not become the only perspective dominating children's daily lives. This is a two years master’s thesis in Library and Information Science.
