A qualitative study of high school student teachers' ideas about libraries and school libraries. Interviews have been conducted with future teachers about the library's role in their education, their views on library functions in high school and whether they as teachers will use the school library. The results show that the students have had some instruction concerning how to use the library as students, but very little as regards their future teaching. The professors of teacher education focus on the fact that the library should be used in high school teaching, not how to use it. Despite this, the student teachers look very positively upon libraries. Libraries play an important part in their education and they are all sure that they as teachers will use the school library, which includes interacting with the librarian. To them, the most important school library function is to allow pupils to seek information.
