Public libraries are the largest mediators of literature to young children in Sweden. They are obligated to pay special attention to children, and to offer various literature and service that meets the needs of different people. It’s important that libraries offer a wide range of literature that shows a diversity of people and relations for children to be able to relate and thereby find the motivation to keep on reading. Norm creativity (normkreativitet) is a method used to challenge and broaden already existing norms. This essay study how Swedish children librarians apply norm creativity in their everyday practice. This is done by conducting a qualitative analysis in which I’ve interviewed five children’s librarians in five randomly selected public libraries about purchase, weeding, selection for storytelling and highlighting of books in the library.  Shove, Pantzar and Watsons practical social theory is used to describe how librarians can either change norms or deliberately or unconsciously help consolidate already prevailing norms in their everyday practice. The theory contains three elements; material, competence and meaning.  The result shows that it´s up to one and each librarian to apply norm creativity and that it´s very different how well-informed and motivated they are. Lack of published materials and problem finding reviews affects the purchases. The librarians also reflect on how some published books have the purpose to show diversity at the expense of quality.
