The aim of this master’s thesis is to develop knowledge about rainbow families self-perceived family identity in relations too their experience of the library's picture book collection. The lack of research about rainbow families’ experiences of the picture book collection and the undertaking of lgbtq-perspectives of the library motivates this study. This quality study was based on a web survey and was answered by adults of rainbow families. The empirical data was analyzed through thematic analysis and theoretical framework drawn from Axel Honneth’s theory of recognition and the notion of literature as mirrors and windows as understood by Rudine Sims Bishop. Recognition is seen as necessary for the positive develop of identity and is based on the notion that every human needs recognition from others to obtain a positive relationship with self. The result shows that the picture book collection is perceived positively and valuable and can allow recognition when aspects of representation, diversity and awareness of norms are reflected in the collection and included in the work of the library. These aspects include representation of rainbow families and lgbtq-identities, inclusion of diversity, and awareness of social norms regarding families and gender. The result also acknowledge that the rainbow families experience somewhat lack of representation, diversity, and awareness of norms in the collection which affects the strengthening of the identity. The self-perceived family identity can be seen strengthen when the families wishes regarding representation, diversity and norms are meet in the library’s work with the picture book collection.
