Although many authors have written about Valvasor's probate inventories none of them has undertaken an analysis of the books that remained at the Bogensperk castle and in Krsko after his death. The article briefly presents the four inventories that follow each other chronologically and have been named after the place in which they had been created, namely in Bogensperk, Krsko, Ljubljana, and Knezija. It was possible, through an investigation of online catalogs, to determine most of the book titles that in the inventories were noted only approximately or were merely described, as well as the majority of their authors and the place and date of their publication. An analysis of the inventories of Bogensperk and Krsko gives an insight into Valvasor's plans that due to his untimely death were never realized. PUBLICATION ABSTRACT
