LibGuides: Referencing and Avoiding Plagiarism: Harvard

The Harvard referencing style is one of the main styles used in the National College of Ireland. It is also known as the ‘author date’ system. It is one of the most common systems used internationally and is frequently the standard house style for academic journals.

The Harvard style records just the author surname and publication year within the text of the written work and then provides the full bibliographic details in the list of references at the end, which is titled Bibliography.

NB: Other referencing styles such as APA or IEEE may be used by your course – please consult with your lecturer to confirm which style they require you to use.

When using the Harvard referencing style, a reference needs to be made at the exact point in your writing where you use or refer to information from another source. This consists of a short, basic reference (Author, Year) inserted every time you use or refer to someone else’s work in-text.

Example:

“In recent years, there have been significant advances in the development of high-performance personal computers and networks” (Connolly and Begg, 2015, p. 107).

NB: When a direct quote is used, include the page number(s) the quote was taken from and add it to the in-text citation as shown above. If you are paraphrasing, you do not need to include the page number(s) in your in-text citation.

When using the Harvard referencing style, a reference needs to be made in your bibliography at the end of your work. A bibliography provides comprehensive details of all the sources used throughout your written work.

If a reader wants to know the full details of a source you have used, they can refer to your bibliography.
