The purpose of this thesis is to investigate how children's librarians at public librarieswork to promote reading towards children between the ages of 8-12 and to see if theirreading promotion only consists of printed fiction. The research questions for the thesisare the following: • How do the children's librarian conduct their reading promotion work? • How do children's librarians use different kinds of media in the readingpromotion work? • Which methods do children's librarians use in the reading promotion work? The purpose has been achieved and the research questions has been answered throughresearch interviews with children's librarians who work at public libraries. To analyzethe responses from the interviews, we have used a theory about different approachestowards reading and Jofrid Karner Smidt's theory of the librarian as a mediator ofliterature. The conclusions of the thesis are that there are great similarities in how thechildren’s librarians we have interviewed work with reading promotion and what kindof reading-promoting methods they use.
