The book provides easy access to the archival materials preserved in Alojzij Šuštar Collection, which are otherwise accessible only to a limited degree. It documents the struggle of Archbishop Šuštar to force the communist government to grant basic freedoms to Catholics, such as the right not to work on Christmas. It follows his activities in the process of Slovenia becoming an independent state. Therefore, the book is an unavoidable source for studying more recent Slovenian history.
