Referencing using the author-date (Harvard) system

About this resource

The author–date referencing system is customary in the physical, natural and social sciences as well as in the humanities. It is a widely used referencing style at Deakin.

This resource explains some of the more common applications of the author–date system. It is based on the Style manual for authors, editors and printers, 6th edn, 2002. Page numbers are provided so that you can check the information yourself or read further.

A word of warning – you should always check your unit guide and/or with your academic staff (unit chair, lecturer or tutor) to make sure that this is the correct system for your unit. Also, because people may interpret the author–date system differently, you should check exactly what’s required for your assignment.

Referencing and avoiding plagiarism

You must reference all material you use from all sources and acknowledge your source each time you use an idea or finding from someone’s work. Sources such as books, journals, reports, newspapers, interviews, radio and television and information from the Internet must be cited in the body of your paper. Information from Deakin study guides and readers must also be acknowledged. A reference list should be provided at the end of your paper giving details of the sources you cited in the body of the paper.

It is necessary to reference your sources each time you:

Author–date referencing system (pp. 188–208)

The author–date system consists of two elements:

  1. in–text citations, which are provided in the body of the paper
  2. a reference list at the end of the paper giving full bibliographic details for the references cited in the paper.

Part 1: In-text citations

The author–date system is so named because in the body of the writer’s text, citations consist of two elements:

Page numbers are included if appropriate, that is, for quotations, and if the ideas or data you have used are from a specific page or pages of a work.

The family name of the author or authors and date can be in parentheses.

Reading widely is the best way to improve vocabulary and also to develop a sense of what academic writing in a particular discipline involves (Hay, Bochner & Dungey 1997).
(Hay, Bochner & Dungey 1997) in–text citation

Or the family name of the author or authors can be included in your sentence.

Hay, Bochner and Dungey (1997) explain that reading is the best way to improve vocabulary and also to develop a sense of what academic writing in a particular discipline involves.
Hay, Bochner & Dungey (1997) in–text citation


Note that ‘and’ is used when the family names are part of your sentence, but an ampersand (&) when the names are in parentheses.

The page number must be included if you incorporate a quotation.


Hay, Bochner and Dungey (1997, p. 110) comment, ‘Good writers are necessarily good readers’.
Hay, Bochner & Dungey (1997, p. 110) in–text citation

Two or three authors (p. 193)

If a work is written by two authors, or three authors, as in the example above, the in-text citation provides the family names of the authors in the order in which they appear on the title page of the work.

More than three authors (p. 193)

If a work has more than three authors, in text use only the family name of the first–listed author followed by the expression ‘et al.’ (meaning ‘and others’).

Ellis et al. (2004) explain that learning will improve if students are made aware of how discussions can help them achieve the learning objectives of various units and if they are shown how to best take part in both online and face–to–face discussions.

Or

Learning will improve if students are made aware of how discussions can help them achieve the learning objectives of various units and if they are shown how to best take part in both online and face–to–face discussions (Ellis et al. 2004).
The reference list entry for this source should provide the names of all the authors in the order in which they appear on the title page of the work. (See the sample reference list provided later in this resource.)

Secondary sources (pp. 198–199)

When you read one author (secondary) who cites another (primary), provide both primary and secondary authors’ family names in the in-text citation. In the reference list provide the details of only the source you have read.

In the example below you have read Cotterall and Cohen, who refer to Donato, but you have not read Donato yourself.

Donato (cited in Cotterall & Cohen 2003) explains the concept of scaffolding, which supports learners as they extend their competence and skills.

The reference list entry should give details of the work by Cotterall and Cohen. (See the sample reference list provided later in this resource.)

No ascertainable author (p. 197)

Works that do not indicate the name of an author are cited in text by title (and year of publication, plus page number, if appropriate).

English for academic purposes (1987) provides authentic texts for students to practise study skills for higher education.

A work that is referred to by title in text is listed under that title in the reference list. (See the sample reference list provided later in this resource.)

Internet sources

For information and examples of how to reference webpages and material from electronic databases according to the author–date system, consult Referencing internet and other electronic sources.

Part 2: Reference list

In-text citations provide only brief facts about sources. It is therefore necessary to have a method for identifying sources in full. This is the function of the reference list. It should appear at the end of the paper and provide the full bibliographic information about the sources cited in text. The in–text citation should lead the reader to its full description in the reference list. Thus, it is essential that the in–text citation and the related entry in the reference list should match in regard to the family name of the author or authors and the year of publication.

Take note of the following points with regard to compiling a reference list:

Reproduced below are sample reference list entries for types of texts that students commonly need to reference.

Work in an edited collection (p. 202)


In your assignments you may want to refer to an article, report, essay or chapter in an edited collection containing contributions by a number of writers. In this instance, you need to acknowledge the author whose work you are discussing with an in-text citation. In the example that follows, the in–text citation should be to Chang and Swales. The reference list entry should give details of the work and indicate the collection in which the work appears. It should be set out as follows:

Tips and strategies

The above explanations and examples provide a general introduction to the author–date style of referencing. You also need to consult your unit outline and assignment description for specific requirements. Some faculties and schools at Deakin have produced their own style guides and you will need to follow these when undertaking units they offer. Be aware that there are slight, and acceptable, variations in the author–date style (in regard to punctuation and capitalisation) that may be used by faculties and schools.

You do not need to memorise the details for setting out a reference list. However, you do need to be consistent and to have a source you can refer to for checking details. Use the Style manual, details provided below.
