The purpose of this Master´s thesis is to examine how children’s needs, based on the Convention on the Rights of the Child, are provided for by the librarians when they have the opportunity to create new libraries. We also examine if children have been involved in the process and in that case to what extent. Our theoretical perspective is based on Marianne Andersson’s and Dorte Skot-Hansen’s model of the four different functions the library can have for their users. In order to illustrate the degree of children’s involvement we use Roger Hart’s model of participation. The thesis is based on qualitative interviews with seven informants working at six different libraries. As a result of the thesis we can see that priority have been given to the function concerning how to find your way in the library as a user. The informants also wanted to have a library that appeals to the children by offering possibilities to play and be creative. The thesis shows that the informants are of the opinion that it is an important issue to let the children participate in the process. Despite this the children has in practice not been particularly involved.
