The Harvard and IEEE referencing styles are the most commonly used referencing styles for this subject. The Harvard style records the author surname and publication year within your written work and then provides a Bibliography at the end of your work. The IEEE style uses a numerical system within your written work which then corresponds to the list of references at the end of your work.
Which style do you choose? You will need to consult with your lecturer to find out which referencing style they require you to use.
See the Harvard section or the IEEE section of the NCI Library Referencing and Avoiding Plagiarism LibGuide for further details on how to use these referencing styles.
Harvard referencing consists of two components:
The examples given below are for books with a single author.
In-text citations:
When using the Harvard referencing style, a reference needs to be made at the point at which a source is referred to in the text of your work. This consists of a short, basic reference (Author, Year) inserted every time you use or refer to someone else’s work in-text.

Reidy (2015) suggests that it may be difficult to fill some vacancies as the role may be thought to be low paid or considered to be difficult. |
Direct quote |
“Some vacancies are difficult to fill due to the nature of the job itself. It may be perceived to be unpleasant, dangerous, badly paid or too stressful” (Reidy, 2015, p. 46). |
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 show above. If you are paraphrasing, you do not need to include the page number(s) in your in-text citation.
Bibliography reference:
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 the sources used throughout your written work.
Example | Reidy, L. (2015) Make that grade: Human resource management. 4th edn. Dublin: Gill and Macmillan. |
IEEE referencing consists of two components:
The examples given below are for books with a single author.
In-text citations:
When using the IEEE referencing style, a reference needs to be made at the point at which a source is referred to in the text of your work. This consists of a short, basic numerical reference in square brackets (e.g. [1]).
Paraphrase/summary |
The physical systems which are used during processing of applications can be termed as computing substrate [1]. |
Direct quote |
Marinescu [1, p. 56] defines computing substrate as “a generic term for the physical systems used during the processing of an application.” |
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 show above. If you are paraphrasing, you do not need to include the page number(s) in your in-text citation.
List of references:
When using the IEEE referencing style, a reference needs to be made in a list of references at the end of your work. The list of references provides comprehensive details of the sources used throughout your written work and is ordered numerically.
Example |
[1] D. C. Marinescu, Cloud Computing: Theory and Practice, 2nd ed. Cambridge, MA: Elsevier, 2018. [2] T. Connolly and C. Begg, Database Systems: A Practical Approach to Design, Implementation and Management, 6th ed. London: Pearson, 2015. |
