The aim of this Bachelor’s thesis is to further knowledge of how the amendment to the Swedish education act relating to access to school libraries has been implemented. The studys’ starting point has been the idea that the act has had an impact on the development of school libraries. The research questions guiding the study were: In what ways do principals actively strive to ensure that school pupils have access to a school library? What opportunities and obstacles emerge in the implementation of the amendment? How do principals view school libraries? To carry out this study an online survey was created and sent to a number of pre-selected school principals. The results were analyzed using implementation theory. According to the results all but one of the investigated schools have access to a library according to their principals’ definitions of access. However, these libraries are not similar to each other and are not used in the same ways. This awakens the issue of how the amendment to the act is interpreted and how the concept of the school library is understood.
