PNU Library was established in 1946 when the university was founded. The Library is comprised of six Subject Libraries, including the Literature & Arts Library, the Humanities & Social Sciences Library, the Science & Engineering Libronary (in the central library building), the Library 2 (Depository, Reading Rooms), the Law Library in Busan Campus, the Medicine and Life Science Library on Yangsan Campus, and the Nano & Life Science Library on Miryang Campus.
- The Library also operates individual reference rooms such as the Historical Korean Literature, iCOMMONS, and the North Korea Collection, and various specialized collections including the UN/EU/IMF Collection, the International Education Program Collection, the Window on America, the Bibliotherapy Collection, the Map Collection, and Job Information.
- The Library aims to provide customized services to meet specific needs, including the Library Instruction Program, PNU-SCI related services, and the Bibliotherapy Program. The Library automation system based on XML also enables online and mobile customized services to contribute to the improvement of efficiency in research and education. In 2010, the government-sponsored Foreign Research Information Center (FRIC : Engineering) was created. With the completion of the Main Library extension on the Busan Campus in 2011, the Library is now providing more convenient services in a more pleasant environment.
