Some source books for West Africa history

In his recent book on the Royal African Company, K. G. Davies remarked that he had found himself obliged to conduct his research as though he were working on Ancient History. I have since experienced the same feeling when dealing with a more varied range of material, and this article is a plea for subjecting the sources for African history to that kind of critical appraisal which has customarily been applied to Greek and Roman authors. In my case I was concerned only with the old European forts in West Africa, and from an antiquarian viewpoint, but the same considerations must apply more generally, and the examples that follow will, I trust, stimulate investigation of the writers where they deal with other topics.
