We present three projects of digitization in Slovenia: the Digital library of Slovenia – digitization of national cultural heritage, Kamra – digitization of regional cultural heritage, and SIstory – digitization of Slovenian historical literature and historical sources as a part of Slovenian cultural heritage. The focus in the paper is on the latter. The project was launched at the Institute for Contemporary History in Ljubljana with the emphasis on the needs and requirements of the whole research community, i.e., historians. SIstory takes part in DARIAH – Digital Research Infrastructure for the Arts and Humanities. The main aim of this initiative is to provide a coordinated infrastructure for supporting preservation of cultural heritage in Europe, providing access to research material from Arts and Humanities, and enhancing digital scholarship in the Humanities and Arts across Europe.
