The Jagiellonian Library together with the Medical College Library and the departmental and institutional libraries make up the library-information system of the Jagiellonian University. Thanks to its extensive collection of Polish publications, it is known as a national library.
Currently, the Library processes and archives all Polish publications printed in Poland and abroad. The Library also collects foreign scholarly literature in fields that relate to the University's areas of research and coursework. Priorities include cultural studies, linguistics, literary studies, art and religious studies. All the Polish publications and valuable foreign items constitute a National Library Archive, and are therefore under extra protection.
Due to the nature of the collection and to fulfill its functions, the Library is obliged to take particular care to protect its resources, which impacts on the extent and manner of circulation. The Jagiellonian Library also offers Internet access to electronic versions of scholarly journals and electronic databases.
