Important new knowledge has been achieved, especially in the fields of baroque painting, sculpture and architecture. Some research results represent decisive revisions of the hitherto views, as they threw new light on the artistic development, argumentedly reversed established assertions and created a new basis for the future investigations. As a result of the work of the Institute's researchers and of constructive scientific collaboration in Slovenia and abroad the periodical Acta historiae artis Slovenica has been published (in 1999-2003 five volumes were issued), which during this period achieved international reputation. In 2003 the Institute started publishing a new periodical Umetnostna kronika (Art Chronicle), that immediately attracted exceptional attention of the whole branch. Several monographs were published and lectures of several distinguished scholars were organized.
