Harvard style referencing, as per University regulation.

To get accustomed to university regulations for submitting assignments we were asked to attend a lecture that took place in the University library,  this lecture taught us how to use the Universities online library and how to reference Books, articles and newspaper clips properly. 

Here are some examples;

Murray, H. J. R. (1952). A History of Board Games Other Than Chess. London: Oxford University Press. 12-18.

Robertson, J & Howells, C. 2008, "Computer Games Design: Opportunities for successful learning", Computer & Education, vol 50, no. 2, pp. 559-578.
