This master’s thesis will try to describe the beginning and development towards a modern public library of the town library in Karlskrona between 1906 and 1959. The specific years refers to the year the library was established and the year it moved to the new library building in the centre of Karlskrona. The aim of the thesis has been to do this historical description and to look at the course from the perspective of the national policies and development for the Swedish modern public library. The thesis is based mainly on reports of the proceedings of the public library and other biographical documents and literature, which has been found in two local archives. Criticism of the sources, chronological description and a hermeneutic approach has been used as a method to analyse the different documents. The thesis starts out from which interests created the library, in what way the library was affected by the national library reorganisation in 1930 and what characterised the long process of reaching access to enough space for a fully acceptable activity, which has been the main issue throughout the history and therefore this thesis. A general observation of the development of the town library of Karlskrona is that it starts and follows very well with the national policies and development of the activity of the modern public library. This is not surprising as, for one reason, all public libraries were more or less financially dependent on subsidies and organizational support.
