An account of the Nordic media welfare state that does not consider the library sector, its historical mandates, and the role it plays in securing universal access to media content while also contributing to sustaining the media industries, is missing a piece. With this chapter, we aim to contribute to a deeper understanding of the role of public libraries in relation to a wider media context. As holders of collections of media – books, but also audio and audiovisual media – as well as important enablers of public discussions and events, libraries co-exist with media industries in multiple ways: They purchase media content, promote various forms of media, and compete with the mass media for the attention of the public as well as the resources of the state. We ask questions about the intersections between libraries and the media industries: What are their mandates, social remits, and forms of regulation? What are the challenges that face them today? What are their roles within an extended media welfare state?
