Harvard Referencing System is not a specific standard to be used when organizing your references and your reference list. It is merely a method - a so-called author/date citation system.
There are several varieties of Harvard Referencing System.
If you are using a reference management tool you can choose output styles like e.g. Chicago 16th, APA 7th or Harvard. They are all output styles based on the author/date citation system.
When you have to use the Harvard Referencing System, the most important things are:
The listed references are examples of how you can choose to create references/citations in your text.
If you use a reference management tool and select a standard (output style), for example APA 6th, the references will look slightly different than the examples.
As long as the principle that the references/citations should include author(s) and year (and references/citations must be in brackets in the text) are met, there may well be variations in the layout. Therefore, feel free to choose a standard, a way to create your references/citations. The most important thing is that your references are consistent in their structure.
You can create references/citations in the text in different ways:
How to refer to sources with more than one author (if you are using a reference management tool, the output style determines how to refer to sources with more than one author):
Direct quotes from the original sources must be clearly marked as quotes by insertion, use of italics and/or use of quotation marks. You must add the exact page numbers from the source, e.g. "Contracts are overused primarily when their usefulness is perceived to be greater than their cost" (Roxenhall and Ghauri 2004, p. 261).
If you do not refer to (cite) specific sections, do not refer to a specific page number, unless there is a specific reason to do it, for example when you refer to a specific table or graph.
If it is not possible (or is too expensive or time consuming) to find the original source, you should refer to (cite) both the original source and the source referring to the original source, e.g.:
In this way, you mention both the original source and the source you have used.
If you are using Internet sources, you need to refer to (cite) them like this in your text (author/originator and year):
When you quote your own data (eg. from interviews), this has to be clearly marked.
A precise, extensive and consistent reference list is important as it marks the foundation of your knowledge. Others also have to able to refind the sources you use. Your reference list has to:
As long as the principle of organizing your sources by author(s) and year is being fulfilled, you might choose from different varieties in the layout. The most important thing is that your reference list has a consistent structure - so feel free to choose a standard, a way to list your references.
The listed references are examples of how you can choose to list references/sources in your reference list.
If you use a reference management tool and select a standard (output style), for example APA 6th, the sources in your reference list will look slightly different than the examples. It is not so important as long as your references/sources are listed by the author/year method, as long as your reference list is consistent in its structure and your sources are extensive.
