Abstract : The aim of this thesis is to find out how users and libraries are constructed at public library websites in Sweden from a Web 2.0 perspective. We discuss the development of public libraries in Swedish history and the change from an system oriented perspective to a individual oriented perspective and how these perspectives correspond to needs of the library user. We also discuss the concept of web 2.0 and library 2.0. These concepts are open for different interpretations. Some writers believe that web 2.0 and library 2.0 is something radically new and that it will change the public libraries, while other writers claim that these concepts is just a marketing plan. Library 2.0 can roughly be explained as Web 2.0 functions and concepts translated into the library field. The method we use for this study is discourse analysis and a case study on two public library websites. The result shows us that users are constructed at the library website to be active, committed and interested. The library is constructed to be a meeting point for the community and to the citizen. We also conclude that the argument of web 2.0 and the democratic aspect is questionable. The libraries dictate rules for their websites which frames and limits the user interaction.
