This essay seeks to investigate how the public libraries of Sweden market and advertise their services to the public and what circumstances effect that work. The method to investigate this was chosen to be a qualitative inquiry through interviewing six different employees of the Swedish public libraries, all who had different circumstances surrounding the advertising work they did at their respective libraries. The results of the interviews showed that the circumstances in which the different informants worked with marketing varied to several degrees and so their marketing work did also vary greatly. The conclusion of the essay was that most Swedish libraries seem to work with marketing in their own unique way and that the main circumstances that affected this work were dependent on the libraries budget, guidance from their leadership and the librarians marketing knowledge.
