In this presentation, we share our experiences of a course in Media and Information Literacy (MIL) at the University of Borås; it is a professional development course for teachers and school librarians. The course is completely online and is the only one in MIL in higher education in Sweden. Collaborations at different levels are important for the course's implementation, and collaboration between teachers and school librarians enriches the participants' development of teaching within MIL. Several examples of the practical projects carried out as examination tasks are presented.
