The National Library of Indonesia (Indonesian: Perpustakaan Nasional Republik Indonesia, PNRI) is the legal deposit library of Indonesia. It serves primarily as a humanities library alongside several others holding national responsibilities for science and agriculture. The national library was established in 1980 through a decree of the Ministry of Education and Culture and the consolidation of four different libraries. It maintains the status of a non-departmental government institution and is responsible to the President of Indonesia. The earliest collections originated from the library of the National Museum, opened in 1868 and formerly operated by the Royal Batavian Society of Arts and Sciences.
