Harvard Style

This guide shows how to use the Harvard style of referencing

ATU Harvard banner


In Harvard style, the author and year are cited in-text, and full details of the source are given in a reference list.


There are many referencing styles; the Harvard style is one of countless styles available and is the most commonly used one in ATU.

The Library, in consultation with ATU, Galway-Mayo, Dublin Road's Academic Council, have developed a referencing guide based on the Harvard style.

The ATU Galway-Mayo Harvard style is based on British Standard BS ISO 690: 2010. It is an author-date style, where you put the name of the author, the year the information was published and the relevant page number(s) in brackets after the quote or paraphrase in your document. At the end of the document you make a reference list of our sources, in a specific format.


There will be two parts to every reference you use:

  • The in text citation, where you refer to the information you have collected during your research, and
  • The reference list at the end of your text, which gives the full details of the works so that your readers can follow up for themselves


The important thing to remember when referencing is to be consistent with whatever style you are using.


The detailed referencing guide (see below) developed by the Library describes in detail the rules of the Harvard style, along with examples of references for the various information sources you will use including books, e-books, journal articles, newspapers, databases etc.
