Also, Prof. Thilo C. Schadeberg, (Rijksuniversiteit Leiden), has provided some map images as part of a collaborative mapmaking project, Bantu MapMaker, a HyperCard stack for Apple Macintosh. The stack is free and comes with maps and databases especially for the Bantu speaking areas. The stack is now being maintained and developed jointly by Prof. Schadeberg and Dr. John B. Lowe, programmer and co-PI of the CBOLD project.
