This thesis aims to describe the genre of librarypodcasts that have emerged in Sweden since 2013.Through the overall design of a comparative multiplecasestudy, the two pioneering examples ofCirkelpodden and Bibliotekspodden Solen are beingdescribed and compared, in order to contribute to abetter understanding of what these radio productionsconsist of, on what reasons they have been establishedand finally what this practice based on more explicitjournalistic working methods might implicate for theprofession of the public librarian.Thirty-three programs of Cirkelpodden andBibliotekspodden Solen published during 2103–2014 andtwo semi-structured interviews with the librarians ofthe podcasts are analysed through quantitative contentanalysis and qualitative thematic analysis. Thetheoretical framework is principally based on WiebeBijker’s model of two different ways to perceivetechnology: the deterministic view as an autonomousforce, and the constructivist view as an instrumentcontrolled by man.The results show that the main reasons to adopt thisweb 2.0 media format was to improve the library’straditional ways to talk about books. Besidespresenting books and problematizing the inhold of it,the podcasts were used to enhance the job satisfactionand to promote the library. The main conclusion ofthe study is that the these library podcasts could beinterpreted as expressions of an ongoing movementfrom a traditional conveying role of the publiclibrarian, towards a more content producing role, inwhich the podcast is used as an strategic instrumentfor exposing the librarians expertise and for exertingliterary criticism.
