Harvard vs. OSCOLA vs. APA: Which Referencing Style Does Your UK University Use?

Referencing is one of those things nobody explains properly until you've already done it wrong. You spend hours formatting your reference list, submit the assignment, and then your tutor marks you down for using the wrong style entirely — or using the right style but the wrong version of it.

It's more common than it should be. And it's genuinely confusing, because different departments at the same university can use completely different systems. This guide cuts through it.

Why There Are So Many Different Styles

Here's the thing that trips most students up: referencing styles weren't invented to confuse you. Each one exists because different academic disciplines use different types of sources.

Law students cite court cases, statutes, and parliamentary materials — none of which fit neatly into a system designed for books and journal articles. Psychology researchers need to cite statistical reports with precision. Humanities scholars work with literary editions, manuscripts, and translations that have layers of publication history. So each discipline ended up with a system that actually fits what it cites.

The problem is you're rarely told any of this. You're just handed a style guide and expected to get on with it.

Harvard Referencing

Harvard is the default across most UK universities. If you're studying business, economics, management, social sciences, nursing, or engineering, there's a good chance Harvard is what your department uses.

The system works in two parts: a short in-text citation in the body of your work — usually the author's surname and the year in brackets, like (Smith 2023) — and a full reference list at the end, ordered alphabetically by author surname.

The catch with Harvard is that there is no single official version. Unlike APA, which has a governing body and an official manual, Harvard is a broad style with over a hundred institutional variants. The University of Manchester has its own version called Harvard Manchester. Northampton uses Cite Them Right Harvard. Your university almost certainly has its own in-house guide, and the small details — whether you include a comma between author and year, how you format book titles, whether page numbers are required for paraphrases — can differ between institutions.

The rule: always follow your specific university's Harvard guide, not a generic one you found online. The broad strokes are the same everywhere; the details are not.

APA Referencing

APA stands for the American Psychological Association, and it's the standard for psychology at virtually every UK university. You'll also see it used in education, health sciences, and some social science departments.

It looks similar to Harvard on the surface — both use author-date in-text citations — but the differences matter when you're being marked on them.

APA uses a comma between the author and year: (Smith, 2023) rather than (Smith 2023). With three or more authors, you go straight to "et al." from the very first citation — a change introduced in APA 7th edition, which is the current version. Reference titles use sentence case, meaning only the first word and proper nouns are capitalised. DOIs must now be formatted as full hyperlinks rather than plain text.

Unlike Harvard, APA has one definitive source: the APA Publication Manual, currently in its 7th edition (2020). There's no ambiguity about which version to follow. If your department uses APA, APA 7th edition is what they mean.

One thing worth knowing: some universities, including Salford, describe APA 7th edition as their official Harvard scheme. This causes confusion. If your university says they use Harvard but their guide looks like APA, check whether they mean APA 7th — the formatting will tell you.

OSCOLA Referencing

OSCOLA stands for the Oxford Standard for the Citation of Legal Authorities. If you're studying law, this is your system — full stop. It's used by law schools across England and Wales and appears in legal journals and court submissions. There's no real equivalent in law; other styles simply don't account for the types of sources law students work with.

OSCOLA is structurally different from Harvard and APA. Instead of in-text citations, you use footnotes. When you cite a source, you place a superscript number in your text and the full citation appears at the bottom of the page. The reference list — called a bibliography in OSCOLA — comes at the end.

The style has specific formatting rules for every type of legal source: cases, statutes, secondary legislation, Hansard debates, command papers, EU legislation, and more. Each follows a strict format using standard legal abbreviations. For example, a case from the Appeal Cases series is cited with the abbreviation AC, not the full journal title.

The 5th edition of OSCOLA was launched in spring 2026. If you're partway through an assignment, check with your department about which edition they're currently expecting — most institutions are advising students to continue using the 4th edition for the remainder of the 2025–26 academic year.

Other Styles Worth Knowing About

Depending on your subject, you might also encounter:

MHRA (Modern Humanities Research Association) is common in English literature, film studies, and languages. It uses footnotes like OSCOLA, but for a completely different range of sources — literary editions, translations, archive materials.

Vancouver is used in medicine, dentistry, and some nursing programmes. It uses numbered citations in the order they appear in the text, not author-date. You'll see it at institutions with medical schools.

Chicago is less common in the UK than in the US, but it does appear in history departments at some universities, including Salford.

How to Find Out Which Style Your Department Uses

Check these, in this order:

1. Your module handbook or assignment brief — the required referencing style is usually specified here. If it isn't, that's a red flag worth querying with your tutor before you submit.
2. Your university library's referencing guide — search "[your university] referencing guide" and you'll find their official page. Most libraries maintain detailed guides for every style they use.
3. Your personal tutor or module leader — if you're studying across departments (which is common in joint honours and interdisciplinary programmes), different modules may require different styles. Ask rather than assume.
4. Cite Them Right — many UK universities subscribe to this platform, which provides referencing guidance for all major styles. If your university uses it, your login will give you access.

The One Mistake That Gets Students Marked Down

Using the right style but the wrong version of it.

This happens most often with Harvard, because there are so many variants, and with APA, because students use APA 6th when their university expects APA 7th. It also happens when students mix elements from two different styles in the same reference list — an APA in-text citation format with a Harvard-style reference list, for instance.

Pick one guide, follow it consistently, and cross-check the details before you submit. If your university library offers a referencing workshop or one-to-one session, it's worth going — it's one of the faster ways to remove a recurring source of lost marks.

If You'd Rather Just Get It Right

Referencing takes time to learn, and a formatting error in an otherwise strong assignment is a frustrating way to drop marks. If you're working with one of our expert writers or using our proofreading and editing service, we check referencing as standard — Harvard, APA, OSCOLA, or whichever style your university requires. Everything is matched to your institution's specific guide, not a generic template.
