In this paper 89 Dutch 20th century children’s books on flooding are analysed to show how children’s books can be used as a historical source of cultural values and perceptions concerning water and what results such an analysis can yield. Using a form of discourse analysis, three categories of books are identified: conventional, religious, and progressive books. The conventional and religious books are typical of the period until 1970. They describe the Dutch “fight against the water”, are positive about modern technology, and show respect towards authorities such as mayors and the Queen. The main difference is that the religious books interpret floods in religious terms and the conventional books do not, but the practical implications of this difference are limited. The progressive books have nearly all been published after 1970. They are critical about technology, authority and social conditions, and approach nature not only as something that should be controlled, but also as something that should be protected. Their increase in popularity can be linked to trends in Dutch children’s literature, which in turn reflect broader trends in Dutch society. The paper concludes with a few methodological observations and with recommendations for future international-comparative research.
