The Department of English Literature have provided a referencing style guide, based on the MHRA Style Guide, 3rd ed. You can download a copy here, or from Blackboard.
Whenever you refer to another person's work in your own essay, dissertation or article you must acknowledge them and give full details of your source. You risk being accused of plagiarism if you fail to do so.
MHRA referencing distinguishes between citations for primary texts (e.g. novels, poems etc) and secondary texts (e.g. critical works, additional information).
Most in-text citations are in footnotes. Full details (including editions and translation details if appropriate) should be included in the footnotes for the first mention of a text for both primary and secondary texts. After this, a shortened version can be used, either in brackets in the body of the text, or in footnotes. Whichever method you choose, be consistent.
Examples for primary and secondary texts:
In-text, first mention, primary text: (in footnote) Emily Dickinson, The Complete Poems, ed. by Thomas H. Johnson (London: Faber, 1970), p. 172. Further references to this text are from this edition and are given in the text.
In-text, following mentions, primary text: (in body of text) (Dickinson, p.174) or (p.174)
In-text, first mention, secondary text: (in footnote) Brian Vickers, Francis Bacon and Renaissance Prose (Cambridge: Cambridge University Press, 1968), p. 49.
In-text, following mentions, secondary text: (in footnote) Vickers, p. 85.
In bibliography, primary and secondary texts: Dickinson, Emily, The Complete Poems, ed. by Thomas H. Johnson (London: Faber, 1970)
First, refer to your Department's referencing guide linked above. You will find additional examples and explanations in the MHRA Handbook below, and further examples of specific references e.g. government publications using the 'Cite them Right' guide below. If you can't find the answer in either of the guides below, please speak to your Academic Liaison Librarian.
