The object of this master thesis is to question why the sheet music held by libraries is not used more than it is. I have mainly studied the inc idence of any cooperation between the music schools and libraries, whether there has been consultation on the purchase of sheet music and whether the music schools borrowed sheet music from the libraries. For the thesis qualitative methods were used in the form of interviews with ten leaders in music or cultural schools in Sweden. The main study has been focused on the library and music school in Vänersborg. To compare my results and draw conclusions I have used the work of Sanna Taljas: Music, Culture and the Library: an analysis of Discourses. The result of the study showed that there is very little cooperation between the library section for music and the music school. The greatest interest for cooperation appears to come from the library personnel. Both the library and the music school personnel claim insufficient time and money for their lack of cooperation.
