The purpose of this bachelor thesis is to explore experiences of the secondary school librarians' use of educational resources in their teaching and how educational resources can be applied in school libraries. In addition to recognize the challenges school libraries face with educational resources. As well if the chosen six criteria for the educational resources is accomplished by the interviewed secondary school libraries. The study applies six chosen criteria from the educational resources of the National Library of Sweden, that's revealing the important role for the school librarians to support students and teachers with different resources than previously. Not only that, but school librarians have more opportunities to avail educational resources because of the renewal for the educational act, which is that every school must have access to a school library. This opportunity led to school librarians being available to work extensively with educational resources. With these six chosen criteria from the educational resources for this study focus on the teaching in information retrieval, teaching in source criticism, arrange reading promotion activities, planning media buying together with the teacher, participate in annual meetings with teachers and assist with level adapting material for schoolwork. These six chosen criteria have been an important factor to analyze with the help of sociocultural theory, which is to understand how physical and cognitive cooperation with individuals and groups could be managed. The study uses four concepts from the sociocultural perspective to analyze the results from the interviews, which are communication, learning, artifact and mediation. The method for this study is qualitative research which is a semi-structured interview. The interviews were recorded with five school librarians from secondary school through Zoom, due to the pandemic which occurred during the study. 

The result shows the different experience for the five secondary school librarians with the educational resources. The participants consider that the use of the educational resources is an important tool to support students as well as teachers. Even school librarians can appear with or without teachers in the classroom to offer support in students education. The result shows the value of collaboration between school librarians and teachers, especially planning activities and teaching students information retrieval. In that lesson, a school librarian's duty is to demonstrate how to efficiently manage different tools when students are searching. Another significant aspect is that the four concepts from sociocultural theory show different ways that the school librarian can support with educational resources by adjusting the students needs for schoolwork. This can improve school librarians qualifications in work which to support student and teacher. The result of this study indicates the significant role for school librarians to make use of their qualification and support with educational resources to students.
