The purpose of this thesis is to investigate how city librariesmaintain the intellectual freedom in their Internet service. Thediscussion about Internet filters has been quiet in Sweden forseveral years, so I wanted to see if there had been an increased useof filters. I also wanted to see if the city libraries regulated theInternet service in another way. I sent a survey to 100 libraries andgot answer from 83. To explain what intellectual freedom is, I usedStuart Hamilton’s theory about intellectual freedom in the librarycontext. My result was that it had been an increased use of Internetfilters but still the use was rather small. Most of the libraries in thestudy used policies or rules to regulate Internet access on topicslike pornography or racism. Most of the libraries also had theircomputers in an open way, and that could lead to a self censoredinformation seeking for the user. A solution is to have thecomputers in a more hidden way, so the user could have a morefree access to the Internet. My conclusion is that the most librariesdid hamper the intellectual freedom with their use of filter, policiesand/or the placement of the computers. / Program: Bibliotekarie
