How to Reference in Oxford Style

Oxford referencing is a footnote system: a superscript number in the text leads to a footnote giving the full source — John Smith, The Tudor State (London: Academic Press, 2021), p. 45. — with an alphabetical, surname-first bibliography at the end.

The first citation of any source appears in full; repeat citations use a short form (Smith, Tudor State, p. 62) or ibid. when the same source follows immediately. Oxford-style documentary notes are the standard in UK history departments and, in the specialised OSCOLA variant, in law. This guide covers footnote formats for every source type, the ibid. and op. cit. conventions, and the bibliography — and if you would rather see it done properly, Projectsdeal’s UK academics have footnoted essays and dissertations for 115,000+ students since 2001.

Oxford Referencing, Step by Step

Footnote referencing looks fiddly until you see that it runs on three moves: a full first citation, a short form for repeats, and a differently formatted bibliography. Master those and every history essay footnotes itself. Here is each convention with the exact format markers expect.

Every Oxford Referencing Convention, Covered

Worked Example: A Footnote Sequence Done Correctly

Here is how a run of Oxford footnotes should read in practice. Footnote 1, first citation in full: John Smith, The Tudor State (London: Academic Press, 2021), p. 45. Footnote 2, same source and page, immediately after: Ibid. Footnote 3, same source, new page: Ibid., p. 78. Footnote 4, a different work: Mary Jones, ‘Court Politics Reconsidered’, Historical Review, 44 (2019), pp. 210–32 (p. 215). Footnote 5, back to Smith — ibid. is now wrong because Jones intervened, so use the short form: Smith, Tudor State, p. 101. The common mistakes are exactly the ones this sequence avoids: using ibid. across an intervening source, giving the full citation twice, using op. cit. where a short title is clearer, and copying the footnote format into the bibliography instead of inverting the name — the bibliography entry reads Smith, John, The Tudor State (London: Academic Press, 2021), with no page number.

Frequently Asked Questions on Oxford Referencing

1. What is Oxford referencing?
Oxford referencing is a documentary-note system: a superscript number in the text points to a footnote at the bottom of the page giving the full source details, and a bibliography at the end lists every source alphabetically by surname. It is widely used in history and by law departments in the OSCOLA variant.

2. What does a first Oxford footnote look like?
The first citation of a source gives full details, for example: John Smith, The Tudor State (London: Academic Press, 2021), p. 45. Author names appear first name first in footnotes, and the page number points to the exact passage cited.

3. What do I do when I cite the same source again?
Use a short form: surname, shortened title and page number, for example Smith, Tudor State, p. 62. If the new citation immediately follows a footnote to the same source, you may use ibid. instead.

4. What does ibid mean in referencing?
Ibid. is short for the Latin ibidem, meaning ‘in the same place’. It refers to the source in the footnote immediately above: ibid. alone repeats the same page, while ibid., p. 78 cites a different page of the same source. Never use ibid. when the previous footnote contains more than one source.

5. Should I use op. cit. in Oxford referencing?
Most current UK style guides discourage op. cit. because it forces the reader to hunt back for the original footnote. Use the surname-plus-short-title form instead — it is unambiguous however far back the first citation sits. If your department guide still permits op. cit., follow the guide.

6. What is the difference between Oxford and Harvard referencing?
Oxford cites in numbered footnotes with a bibliography; Harvard cites in brackets inside the sentence — (Smith, 2021, p. 45) — with a reference list. Footnotes suit subjects that cite archives and primary sources heavily; Harvard suits subjects that cite by author and date.

7. What is the difference between Oxford referencing and OSCOLA?
OSCOLA is a specialised footnote style for law, built on the same documentary-note principle as Oxford referencing but with precise formats for cases, statutes and legal materials, and its own abbreviation rules. Law students should follow OSCOLA itself, not generic Oxford style.

8. What is the difference between a bibliography and a reference list?
A reference list contains only sources cited in the text; a bibliography can also include background works you consulted but did not cite. Oxford-style essays normally carry a bibliography, arranged alphabetically by surname — with the author’s surname first, unlike in the footnotes.

9. How do I cite a website in Oxford style?
Give the author (or organisation), the page title, the website name, the full URL and your access date, for example: Historic England, ‘Listing and Designation’, Historic England, https://historicengland.org.uk [accessed 12 July 2026]. Access dates matter because web content changes.

10. Do footnotes count towards my word count?
Policies differ: many UK universities exclude footnotes from the word count when they contain only citations, but include discursive footnotes that carry argument. Check your module handbook — and avoid hiding analysis in footnotes, as markers penalise it.

11. Which subjects use Oxford referencing in the UK?
History is the main user, alongside classics, theology and some philosophy and politics departments. Law uses the OSCOLA variant. If your department says ‘footnote referencing’ without naming a style, it usually means Oxford-style documentary notes.

12. How do I format the bibliography in Oxford style?
List every source alphabetically by author surname, with the surname first and no page numbers: Smith, John, The Tudor State (London: Academic Press, 2021). Note the two differences from footnotes — the name is inverted and the specific page reference is dropped.

13. Can Projectsdeal write my essay with Oxford referencing?
Yes. Since 2001 our UK academics have written footnote-referenced essays and dissertations for history, law, classics and theology students — full first citations, correct short forms and a clean bibliography, delivered with a Turnitin report.
