Introduction. We investigated how librarians viewed childhood, children’s participation and their own profes- sional role in relation to these two topics. Recently the Convention on the Rights of the Child became law in Sweden, and we explored the possible effects on the library professional’s role in comparison to a country where little has been done in regard to children’s rights during the past few years. Method. Qualitative interviews were conducted in Sweden and in England. The empirical data consisted of tran- scriptions and note-taking from four interviews conducted in each country. In total we interviewed eight librarians working with children. Analysis. We carried out a qualitative analysis of the empirical data by a basic thematic approach. The analysis consisted of two separate parts - based on the data from Sweden and England respectively - leading up to a final joint discussion and comparison of our results. Results. There was a pattern of viewing the child more often as “becoming” in England. When the child was viewed as “being” in England this was linked to a norm of children feeling safe, happy and playful. The analysis showed that formal training and awareness of children’s rights to participate were greater amongst the Swedish librarians. Still, children were not actively involved in the planning of events at the library. Conclusion. The views conveyed in the Convention on the Rights of the Child is now part of the Swedish librari- ans’ professional role with an emphasis on the right of participation. In the case of English librarians, certain aspects of the convention are important, although the need for children’s participation seems to have been set aside in favor of children’s feeling of safety. This is a two years master’s thesis in Library and Information Science.
