Dissertation referencing: getting it right
How referencing styles differ, why consistency matters more than style choice, and how to avoid the citation errors that cost easy marks.
8 min read · Reviewed 2026 · Written and reviewed by Chris McGarrigle
Referencing exists to let a reader trace every claim back to its source and to give credit for others' ideas; the specific style you use (Harvard, APA 7, Vancouver, MHRA, OSCOLA) matters far less than applying it consistently and following your own department's handbook exactly.
Markers rarely penalise a correctly and consistently applied 'wrong' style as heavily as they penalise a required style applied inconsistently, so the first and most important step is confirming what your handbook actually requires.
This article explains what the major styles have in common and where they diverge, so you can apply your required style with confidence rather than guesswork.
Numeric styles: Vancouver
Vancouver style, common in health and medical sciences, uses numbers in the text (e.g. [1] or superscript 1) that correspond to a numbered reference list in the order sources first appear, not alphabetically. This makes the in-text citation less intrusive to reading but means the reference list order has no relationship to authorship or date.
Footnote styles: MHRA and OSCOLA
MHRA (common in humanities) and OSCOLA (the standard for law) use footnotes rather than in-text parenthetical citations, with a bibliography at the end. OSCOLA has specific conventions for citing cases, statutes and legal commentary that differ substantially from citing books or journal articles, so law students in particular should check the current OSCOLA guide directly rather than relying on general referencing advice.
Common elements across all styles
Whichever style you use, the underlying purpose is the same: enough detail for a reader to locate the exact source, and a citation wherever you use someone else's idea, data, wording or structure, not only for direct quotations.
- Cite paraphrased ideas as well as direct quotations.
- Use a reference manager (Zotero, Mendeley, EndNote) from the start rather than compiling the list by hand at the end.
- Keep primary and secondary sources distinct — cite the original where you can access it.
- Match every in-text citation to an entry in your reference list and vice versa.
Building consistency into your process
Set your reference manager's output style to match your handbook from day one, and run a full consistency check before submission: does every citation have a matching reference-list entry, and does every reference-list entry appear somewhere in the text?
Common mistakes
- Mixing two referencing styles within the same document.
- Citing only direct quotations and forgetting paraphrased ideas need citations too.
- Leaving reference-list formatting until the final night, when errors are hardest to catch.
- Citing a secondary source as if you read the original (check whether 'cited in' is required).
- Ignoring your department's specific handbook in favour of a generic online style guide.
Try this: Reference consistency check
- Confirm the exact style and version required by your handbook.
- Set your reference manager's output style to match it exactly.
- Spot-check ten in-text citations against their reference-list entries.
- Scan the reference list for any entry never cited in the text, and remove it.

- Which referencing style should I use for my dissertation?
- Whichever your department's handbook specifies. Harvard and APA 7 are author-date styles common across many disciplines, Vancouver is numeric and common in health sciences, and MHRA/OSCOLA use footnotes and are common in humanities and law respectively. Consistency with your required style matters more than which style it is.
- Do I need to cite paraphrased ideas, not just quotations?
- Yes. Any idea, argument, data or structure taken from another source needs a citation, whether or not you use their exact wording. Citing only direct quotations is one of the most common referencing errors students make.
- Should I use a reference manager?
- Yes — tools such as Zotero, Mendeley or EndNote reduce formatting errors and let you switch styles automatically if requirements change, and they make the final consistency check between citations and reference list much faster.
