Referencing Guides



Cite Them Right


DCU Library subscribes to Cite Them Right Online, an excellent resource which will help you to reference correctly and avoid plagiarism.

Cite Them Right Online will show you how to  format references and citations for many different sources (books, e-books, online articles, etc) in a number of styles including Harvard, APA, IEEE, MHRA, MLA, and OSCOLA.

Approach Cite Them Right with the type of source you wish to cite and reference, then choose a citation style from a drop-down list.

There is also an accompanying text book and we have several copies in the Library; check the library catalogue for availability


Harvard is one of many citation styles. Even within the Harvard style there are many variations.

DCU Library Guide (pdf) is the Harvard style as interpreted by Cite Them Right.

This guide gives practical examples for both in-text citation and referencing for a variety of sources.


American Psychological Association (APA) referencing style is widely used in the Social Sciences. It is the preferred style for many programmes in the Institute of Eductaion. 

DCU Library Guide lists the most popular citation types with practical examples for both in-text citation and referencing.

Other Style Guides

If you are required to use a citation style other than Harvard and APA, check your school's style-sheet/guidelines. The following is a list of the main citation styles, with links to books and online resources.

Reference Management Tools


Reference Management Tools allow users to easily cite and reference when doing assignments by creating an account and saving references. Although referencing management tools save a huge amount of time, it is still extremely important to know how to reference.

When using referencing tools, particularly the likes of Mendeley / Zotero please use Harvard Cite Them Write output style if you are required to use Harvard style referencing.


Zotero is a free reference management software. At the most basic level, Zotero is a citation manager. It is designed to store, manage, and cite bibliographic references, such as books and articles. In Zotero, each of the references you enter constitutes an item.  Each item contains data (“Metadata”) about the reference. When opened, Zotero displays 3 columns.

Here is a DCU Library Guide - Zotero  to help you. 


Mendeley is a free reference manager and academic social network that can help you organize your research, collaborate with others online, and discover the latest research
