Studies have shown that early literacy is important for both language development and literacy later in life. One of the missions for public libraries in Sweden is to promote language and literacy amongst children, something they often do in collaboration with other professions who also work close to these children. 

The aim of this study is to explore the collaboration between two library departments and a speech therapists’ clinic. 

With a theoretical framework of theory of professions and collaboration theory, semi structured interviews with four respondents, three librarians and one speech therapist, and a document analysis of the organizations governing documents was conducted. A qualitative content analysis was then used to analyze the material, with the research questions and theoretical framework in mind. The study showed that the collaboration between the professions and their departments was longstanding and is active on several levels today. Thanks to a supportive management and anchoring in governing documents, the collaboration is given room in the daily work. All respondents expressed themselves positively about the collaboration and the possibility of learning from each other and work together to reach a goal they cannot reach on their own. They are aware of what the difficulties with their collaboration are and have learned to compromise and work around it.
