"Islamic Manuscripts from Mali" is a collection of twenty-two Islamic manuscripts containing important insights into the life and culture of West Africans during the late Middle Ages and Early Modern Era. The Library of Congress, through a collaborative effort with the Mamma Haidara Commemorative Library of Timbuktu, Mali, is making available online these rare and important documents. The manuscripts are the work of a number of authors and cover a variety of topics, including--but not limited to--astrology, commerce, Islamic law, health care, mysticism, slavery, and agriculture. All of the manuscripts are written in various forms of the Arabic script."
