This thesis is about how the library can help immigrants integrate into the swedish society. By studying leading documents of the libraries in Malmö, Stockholm and Umeå in search for how the relate to work considering immigrants and integration I have studied the library as a bridge between being included and excluded in the society. The thought is that the library opens the door to new worlds both for immigrants and born swedes to obtain knowledge about a culture different from their own. In my thesis I reached the conclusion that library on a day to day basis works with the integrationprocess for immigrants. Although the leading documents should evolve since they show gaps and seem somewhat misguiding in their presentation of the libraries function. The libraries should work more with analysis of the environment that they are active in so that they are more individualized for the people around it. They should also provide activities that shows more of the swedish society for those who might come from another cultural environment, and this should be available on their on language.
