This guide details referencing and citing using the Harvard style of referencing.
Referencing consists of two elements:
a reference list only includes sources you have referred to in the body of your text.
a bibliography includes sources you have referred to in the body of your text AND sources that were part of your background reading that you did not use in your assignment.
You need to include an in-text citation wherever you quote or paraphrase from a source. An in-text citation consists of the last name of the author(s), the year of publication, and a page number if relevant. There are a number of ways of incorporating in-text citations into your work - some examples are provided below.
One author | Two authors | Three authors | Four or more authors |
---|---|---|---|

Secondary referencing |
---|
You use secondary referencing when you want to refer to a source that is mentioned or quoted in the work you are reading. To do this, you add the phrase ‘quoted in’ or ‘cited in’ (depending on whether the author of the secondary source is directly quoting or summarising from the primary source) to your intext citation, along with the details of the source that you are reading. In-text citation examples: West et al. (2007, quoted in Birch, 2017, p. 17) state that… You would then include full references to Birch and The Open University in your reference list as these are the sources that you have read. There is no change to the structure of the full reference for these sources. |
Page numbers |
---|
You should include page numbers in your citation if you are quoting directly from or using ideas from a specific page or set of pages. Add the abbreviation p. (or pp. if more than one page) before the page number(s). Examples: Harris (2015, p. 5) argues that… In the drying process "polyphenol oxidizing reactions" form new flavour compounds (Toker et al., 2020, pp. 585–586)... |
Citing sources published in the same year by the same author |
---|
Add a lower case letter to the date in the in-text citation and in the matching full reference to distinguish between the sources. In text citations: Snow is formed in part because the temperature drops enough that rain freezes (The Open University, 2022a), however the freezing temperature of water is often below 0°C under certain conditions (The Open University, 2022b). Matching full references: The Open University (2022a) '1.2 What are clouds?'. S111: Questions in science. Available at: https://learn2.open.ac.uk/mod/oucontent/view.php?id=1938785§ion=3 (Accessed: 22 November 2022). The Open University (2022b) '1.3.1 Snow and ice'. S111: Questions in science. Available at: https://learn2.open.ac.uk/mod/oucontent/view.php?id=1938785§ion=4.1 (Accessed: 22 November 2022). Note: this only applies when you are using multiple different sources with the same author and year – if you are referring to the same source more than once then you do not need to add a letter to the date. The citation will be the same each time and you only need to include the source once in your reference list. |
