The aim of this Bachelor's thesis is to investigate teachers 'and school librarians' perceptions of school library activities. Six semi-structured interviews  were conducted to collect data. Three school librarians and three teachers were interviewed. Data were first analyzed through a thematic analysis. For the themes that emerged, Loertscher's (2000) taxonomies have been used as a theoretical framework. The themes presented in the results section of the study have the headings; the school library's physical location and staff, flexibility, reading promotion, collaboration, expectations of the professions and wishes. In this study, the results show that the school library's location and staff is an important prerequisite for the activities. The interviews show that the school librarians are flexible. They work at several different schools and adapt to teachers' wishes. A variety of reading-promoting activities emerge in the study. The interviewed school librarians have a higher perceived degree of cooperation compered to the teachers. Teachers' expectations of school librarians are more multifaceted than the other way around. A common wish that school librarians have is that they want more time and opportunities to plan their activities with insight into what teachers are going to work with. One of the study's conclusions is that it does not benefit school library occupation to work against a higher number of pupils than what is advocated by the trade union DIK (2018).
