Jagiellonian Library
Jagiellonian Library (, popular nickname "Jagiellonka") is the library of the Jagiellonian University in Kraków and with almost 6.7 million volumes, one of the biggest libraries in Poland, serving as a public library, university library and part of the Polish national library system. It has a large collection of medieval manuscripts, for example Copernicus' "De Revolutionibus" and Jan Długosz's "Banderia Prutenorum", and a large collection of underground literature (so-called "drugi obieg" or samizdat) from the period of communist rule in Poland (1945–1989). The Jagiellonian also houses the "Berlinka" art collection, whose legal status is in dispute with Germany.

The Main Library is located south of Gregory Hall between Armory Drive and Gregory Drive. The UIUC libraries house the largest collection of books of any public university in the United States, reaching over thirteen million volumes. This number also makes it the third largest academic library overall, behind those of Harvard University and Yale University.
