This thesis analyses how friendship between children is described in four Swedish childrens books, published in 1995-2001 and recommended in Barnbokstipset, which is used in libraries for recommending books. Today there are many childrens books that describe various aspects of childrens everyday lives and these books can have an influence on the children who read them. But I found that there has not been much research about how friendship is described in childrens books, although much has been written about the importance of social relationships with peers for childrens lives and development. I analyze the books one by one with the help of a number of questions and categories that I have constructed beforehand. In the analysis I apply Zick Rubins theory of two different stages in childrens understanding of friendship and William Corsaros theory of interactive space which deals with who is allowed to join in games and friendships and who is not allowed to do so and how this is played out. Some of the conclusions that can be drawn from the analysis is that most of the described friendships contains a lot of emotions and that problems in the relationships are frequently described. The books are to a great extent about being able to get access to the desired interactive space.
