In the Harvard referencing style, is it wrong to put references in footnotes? I have a discussion with my mate about how to reference with the Harvard referencing style.



I would say it is wrong to do the referencing like in the picture below. 

My suggestion was that the footnotes was to explantion of synonyms or something like that and all references should be in the end of the paper work, so the reader have all the references in one or two pages, so it's easier to get an overview of all references.

Am I totally wrong?
As your question is directly about Harvard referencing, I believe all Harvard referencing uses in-text citations. Wikipedia supports this understanding.

Yes, you can use footnotes but they are used for clarification or comments, they are not used for referencing as the image in the question has done [therefore the author has cited improperly].

There are several sub-types of Harvard but ALL of them that I am familiar with are in-text, not based on footnotes (except as noted above).
