The core functions of the National Library of Latvia (NLL) are the collection of national literature, its perpetual storage and the long-term provision of access to it.
The NLL collection (4.5 million units) embraces all branches of knowledge, the fundamental profile being Social Science and the Humanities. Library readers also have access to special collections – rare books, manuscripts, the Lettonica (Latvian) and Baltic Central Library collections, maps, sheet music, sound recordings, graphic publications, ephemera and periodicals. At present, most library activities and events are intended to support higher education, research and life-long learning.
The NLL is a centre of theoretical research into and practical analyses of the activities of Latvian libraries. The Library operates as the centre of Latvia's Interlibrary Loan system, provides library and information services to the Saeima (parliament), and is implementing library-sector standardisation. From its very beginning, the NLL has been responsible for Latvia's national bibliography.
