The paper presents an overview of research on books and their types conducted after the Second World War by Polish bibliologists. The scholars were mostly interested in academic books, popular books, as well as books for children and young adults. They explored their characteristic features, presented them as elements of the publishing repertoire and of serial publications, and discussed their development in various periods. Less interesting to them were the structure and typology of books. In recent years, studies devoted to electronic books as objects of bibliological research have begun to appear. Research on books and their types is also conducted by scholars from other disciplines: historians, historians of literature and historians of education. Their findings are also of interest to bibliologists.
