Here is an interesting website to look at:
(A website dealing with 20th century educational events)
(A South African site providing information on writing a dissertation or thesis)
(A South African site providing information on events in South Africa History)
(The University of South Africa [UNISA] library catalogue)
Remember, however, to always verify and cross-check information before using it. Equally important is the acknowledgement of sources. Remember that failure to do so constitutes plagiarism.
