The International African Bibliography Online (IABO) lists details of more than 4,000 publications each year, with articles from some 1,150 periodicals. The IABO concentrates on publications dealing with the African Continent as a whole, classified according to subjects such as agriculture, and nutrition, anthropology, art, economics and development, education, history and archaeology, languages, law, literature, politics, religion and philosophy, science and social sciences. Titles are also arranged by region, including individual countries, and the African Diaspora is included as a category of its own. Articles and monographs are presented separately in the IABO.
