This master thesis explores the librarian discourses in children’s literature published between the years of 2000-2020. The purpose of this essay is to explore however the technical development in the real-life libraries also can be found in the libraries described in children’s literature. I have also explored how these technical tools and work tasks are portrayed in the literature. The material consists of 18 children’s novels. The theory and method used are Laclau and Mouffe’s discourse theory combined with a model created by Hedemark and Hedman in 2002. My version of the model contains four fields: Names, traits and qualities, themes of which librarians are discussed and discourses. The major questions for this study are: - What discourses about librarians, their tasks and traits, can be found in children’s literature published between 2000-2020? - How do these librarian discourses differ from discourses found in previous research about librarian discourses in literature? - How is the technical development in libraries, compared to the real-life libraries, portrayed in children’s literature? How are the librarians’ technical tasks presented and what tools are used for these technical tasks? The findings of the essay are four different librarian discourses; The Buddy Librarian, The Structured Librarian, The Mythical Librarian and The Pedagogical Librarian. Some of the librarian discourses are similar to the ones in previous research, but most of them do not resonate with the earlier studies. In the novels, many of the librarians have technical tasks, such as checking out books on the computer, which resonates with the real-life libraries. The conclusion of the master thesis, is that many of the children’s novels do portray librarians who do technical task as a part of their daily work. This is a two years master's thesis in Library and information science.
