The topic of this bachelor thesis is the art of book talk. Book talk is when a librarian orally presents a book in front of a group of people, in this thesis, a group of children. The first part of the thesis treats book talk as a method and its development. It will also go through which role book talk plays in the daily work of a children's librarian today, and if they got any education in book talk during their librarian education. The purpose of this study is to investigate and compare Lev Vygotskij's pedagogical theories on fantasy and creativity to book talk performed by children's librarians. Interviews were made with three children's librarians at two libraries in a quite big town in Sweden. Book talks were also observed at some occasions. The result of this study is that the interviewed librarians are not mainly aware of which pedagogical methods used in their book talks (and in preparing them). Yet it is possible, by analysing the material from the interviews and observations, to find similarities between book talk and Vygotskij's theories.
