Credo Reference is an online database which provides access to a growing selection of reference books such as subject encyclopedias and dictionaries.
Credo has tapped into its own content to create this useful guide:
The Libraries' databases American Mosaic, Black Studies Center and Oxford African American Studies Center all have timelines and other information on African history. World History in Context also contains information on the history of Africa beginning before 500 AD up to the 20th century.
STLCC Libraries have many books on the continent's history and that of particular countries. In the search box below, try a subject search for Africa - History or for a particular country, e.g. Angola - History. Below the box are just a couple I've found edifying.
