Popular Referencing Styles
Referencing and citation is the process of acknowledging the sources you have used when writing your work. Referencing has become an essential component of all forms of academic writing, with the primary goals of discouraging plagiarism and recognizing academics, researchers, and others for their contributions to the advancement of knowledge. In addition, precise referencing and citation also allows the reader of your work to easily identify those sources used in your work and to follow up on them if necessary.
Academic institutions and publications worldwide use a variety of referencing styles. Each has its own rules and conventions for formatting sources. Some of the most widely used styles include:
- APA (American Psychological Association)
- MLA (Modern Language Association)
- Harvard Style
- IEEE (Institute of Electrical and Electronics Engineers)
- ACS (American Chemical Society)
- AMA (American Medical Association)
- AGLC (Australian Guide to Legal Citation)
- CSE (Council of Science Editors)
The choice of style often depends on the field of study, with each tailored to meet the needs of its discipline.

General Format of Referencing
The arrangement in reference style determine which reference format or the order

Forms of Referencing
There are many referencing styles, but they usually consist of two forms:
- in-text citation/reference
- out-text referencing/ bibliography
- A citation wherever you refer to a source in your text
In-text citations are the short citations you include in the written text that help a reader understand which sources you are quoting or referring to in your writing e.g. (McEwan, 2022) or (1).
b. A reference list or bibliography at the end listing full details of all your sources.
References are the full details of the source you have cited in your writing. Full details about the sources you have used in your writing are included in your reference list. e.g. Smith, J. (2013) Statistical analysis. 2nd ed. London: Penguin.
The most common method of referencing in UK universities is Harvard style, which uses author-date citations in the text.
