The Royal Library (KB) of Sweden harbours great collections of different objects through a special law from 1661. This master degree paper is exploring a part of KB’s digitisation of those collections. It deals with the questions about what the KB had chosen for digitisation, why those choices were maid and who is responsible for making these decisions. The paper will also for example seek out different patterns and trends in the information. The questions were answered through examining10 of the KB’s earlier digitisation projects and tests with qualitative methods: personal interviews, interviews by phone and questionnaires. The interviews and questionnaires were performed with informants at KB. General information about KB’s digitisation and the results from the interviews and questionnaires are presented partly with each individual test and project and partly in two analyse tables. KB had chosen different kinds of objects from their collections, for example older books and posters. The main reasons for digitising objects and collections were preserving and giving access to the collections and objects. The copyright were important to notice and there were also marketing of the collections and the testing of technology. The people responsible for the decision-making were partly KB’s head council and partly the informants involved with the projects. / Uppsatsnivå: D
