This bachelor thesis has as its aim to investigate the Swedish librarians’ views and opinions about censorship of their libraries' collections as well as building information about the context of challenges against the same collections. In Sweden the public can't, unlike in the USA, formally challenge material and are forced to”complain” the subject with a librarian. What is deemed as controversial, both by the public and by the librarians themselves are explored through qualitative interviews with six librarians. The librarian's find that they rarely experience anything that can be called aggression or organized protests like those found in the USA. The main arguments against parts of the libraries' collections seem to come from parents wanting to protect their children against what they deem to be ”unfitting” themes, such as sex or sexuality or works deemed undignified, such as collections of jokes. The librarians themselves are against censorship as a whole, but are very restrictive about the libraries' collections of electronic media. Video games and movies have to pass a very stern checklist to be procured resulting in a meager selection for the libraries' visitors, compared to the selection of literature or magazines.
