The collections of 19th to 20th century books and periodicals and the microform collections are open to all persons over 18 years of age who have joined the library and have received a library card.
The special collections (manuscripts, old books, prints, cartography, numismatics) can only be used by persons who can document such a need (e.g. through a letter of recommendation from their supervisor, identification as an academic worker, permission from the Ossolineum’s director, or who are retired academic staff). The decision to grant the right to use the special collections is taken by the head of the appropriate department or room.
