The National Museum of Somalia in Mogadishu (3,000 volumes) maintains a highly specialized library dealing primarily with African and Somali culture, government, and history. The National Library of Higher Education and Culture has 9,000 volumes, and the Somali Institute of Public Administration also has a book collection; both are in Mogadishu. The National Museum in Mogadishu is a restored residence of the viceroy of the sultan of Zanzibar. Besides its comprehensive collection of Somali ethnographic material, the museum has local art objects, fossils, and old coins. Due to the long civil conflict in the country during much of the 1990s, little is known about the state of these institutions.
