 Since both editions have a variety of diplomatic and linguistic errors, and readings are often unreliable and do not conform to modern principles of publishing critical editions of medieval documents, Yugoslav Academy decided to publish a new edition of "Acta Croatica" in accordance with critical palaeographic, linguistic, transliteration and diplomatic principles for publications of medieval sources.In 1917 this task was entrusted to the linguist Stjepan Ivšić, who critically processed much of the material, which was also expanded with newly discovered documents to 1541.Since the early 1970s, Ivšić's work was continued by Josip Bratulić and Miroslav Kurelac.
