A citation can look wrong even when the punctuation is perfect. OSCOLA title capitalization is one of the easiest places to slip.
Many writers carry habits over from other legal citation styles like APA, MLA, or Chicago, then end up with capitals in the wrong spots. The fix is simple: use title case for cited titles, cap the major words, and leave most small linking words lowercase.
Key Takeaways
- OSCOLA uses title case for cited titles: capitalize major words (nouns, verbs, adjectives, adverbs, pronouns, proper names) and lowercase minor words (articles, prepositions, conjunctions like “and”, “or”, “the”) unless they start the title or subtitle.
- Always capitalize the first word of a subtitle after a colon, even if it’s a minor word, e.g., Freedom of Expression: A Comparative Study.
- Ignore the source’s own capitalization (e.g., all lowercase or all caps); apply OSCOLA rules consistently in footnotes and bibliographies.
- Retain standard forms for brand names, acronyms, and proper nouns like “eBay” or “UK”, while following title case for general words.
- Use title case in citations, but sentence case in your own prose discussing titles.
The core rule for capitalizing titles in OSCOLA
OSCOLA’s basic rule is plain. In cited titles, capitalize major words. Keep minor words, such as “and”, “or”, “the”, and “for”, in lowercase unless they start the title or subtitle. While many look for an OSCOLA 5th edition, the OSCOLA 4th edition remains the standard (Oxford Law Faculty). You can see that rule in the University of London’s OSCOLA guidance and in Oxford’s OSCOLA guide.
In practice, “major words in a title” means the words carrying the main meaning. Nouns, verbs, adjectives, adverbs, pronouns, and proper names usually take capitals. Short function words usually don’t.
These examples, using italics for titles of authored books and edited books among other secondary sources, show the pattern quickly for journal articles and more:
| Source type | Correct capitalization | Incorrect capitalization |
|---|---|---|
| Authored books | The Law of Restitution | The law of restitution |
| Journal articles | ‘Liability for Harm in Public Law’ | ‘Liability For Harm In Public Law’ |
| Chapter in edited books | ‘Equity and the Rule of Law’ | ‘Equity And the Rule of Law’ |
| Statute | Human Rights Act 1998 | Human rights Act 1998 |
| Title with subtitle | Company Law: Theory and Practice | Company Law: theory and Practice |
The pattern matters because OSCOLA title capitalization is not random styling. It tells the reader which words carry weight in the title. These rules also ensure consistency in your footnote style and bibliography. Once you know that, most decisions become easy.
There’s also a useful limit here. OSCOLA is not asking you to capitalize every word. If you turn every small word into a capital, the citation starts to look like a different style guide.
Where writers usually get it wrong
Most mistakes happen with small words. Articles, short prepositions, and coordinating conjunctions often stay lowercase when they appear in the middle of a title. Newspaper articles and other secondary sources follow the same logic.
For example, these are right:
- An Introduction to the Law of Trusts
- ‘Rights of Audience in Criminal Courts’
- Regulation of Investigatory Powers Act 2000
These are wrong:
- An Introduction To the Law of Trusts
- ‘Rights Of Audience In Criminal Courts’
- Regulation Of Investigatory Powers Act 2000
The subtitle rule also catches people out. If a subtitle begins after a colon, capitalize major words starting with its first word, even if that word is usually minor.
If a small word starts a subtitle, give it a capital.
So write:
- Freedom of Expression: A Comparative Study
- ‘Public Law Remedies: The Limits of Review’
Not:
- Freedom of Expression: a Comparative Study
- ‘Public Law Remedies: the Limits of Review’
Another common problem is importing habits from the source itself. A webpage, online database entry, or other source may use odd capitalization, all lowercase, or all caps. Under OSCOLA, you should still apply the style’s rule to the title in footnote style, while keeping true proper names intact. For web sources from online databases or webpages, enclose URLs in angled brackets and include the accessed date requirement. The ULaw OSCOLA reference guide gives the same major-word approach.
So this is right:
- ‘Guide to Judicial Review in England and Wales’
- ‘Tax Issues for eBay Sellers’
And this is wrong:
- ‘guide to judicial review in england and wales’
- ‘Tax Issues for Ebay Sellers’
That last pair shows an important edge case. General title words follow OSCOLA capitalization, but brand names, acronyms, and proper names keep their normal form. Write “UK”, not “Uk”. Write “eBay”, not “Ebay”.
Sentence case versus title case under OSCOLA
This point causes more confusion than it should. For titles in citations, OSCOLA uses title case, not sentence case.
That means you would cite an article using single quotation marks as ‘Damages in Contract and Tort’, not ‘Damages in contract and tort’. You would cite a book with italics for titles as Principles of Administrative Law, not Principles of administrative law.
Sentence case still has a place, but usually in your own prose, not in the cited title. For example:
- In prose: Smith discusses damages in contract and tort.
- In a citation: Author names like John Smith come before the title, as in John Smith, ‘Damages in Contract and Tort’ (2025) 41 LS 120, complete with page numbers and pinpoint references for secondary sources.
That distinction helps when you’re writing footnotes and surrounding text at the same time, including in footnote style with common elements like ibid. Your sentence follows normal grammar. The title inside the citation follows OSCOLA.
It also helps to know what OSCOLA doesn’t copy from other styles. If you’re used to the Chicago title capitalization rules, you may expect a blanket rule that always capitalizes the last word. OSCOLA guidance is framed around major and minor words instead. So don’t force a capital onto a minor word only because it happens to sit at the end.
The safest editing check is simple. Read the title word by word. Ask whether each word carries meaning or mainly links other words together. If it carries the title’s substance, capitalize it. If it’s a small connector, leave it lowercase unless it starts the title or subtitle.
If you switch between referencing systems, a quick comparison of title case styles can help you spot where OSCOLA differs before those habits creep into your footnotes.
Frequently Asked Questions
What is the core rule for OSCOLA title capitalization?
OSCOLA requires title case for cited titles, capitalizing major words that carry the main meaning (nouns, verbs, adjectives, adverbs, pronouns, proper names) while keeping minor linking words lowercase. Examples include The Law of Restitution or ‘Liability for Harm in Public Law’. This ensures consistency and highlights key terms in footnotes and bibliographies.
Do subtitles change the capitalization rules?
Yes, capitalize the first word of a subtitle after a colon, even if it’s a minor word like “A” or “The”. For instance, write Company Law: Theory and Practice or ‘Public Law Remedies: The Limits of Review’. Then apply standard title case to the remaining major words in the subtitle.
Should I copy the capitalization from the source itself?
No, always standardize to OSCOLA title case regardless of the source’s style, such as webpages in all lowercase or all caps. Retain only proper forms for brands (e.g., “eBay”) and acronyms (e.g., “UK”). This keeps citations uniform and professional.
Title case or sentence case for OSCOLA citations?
Use title case for titles within citations, like Principles of Administrative Law or ‘Damages in Contract and Tort’. Sentence case applies only to your own prose, e.g., “damages in contract and tort”. This distinction maintains OSCOLA’s precise footnote style.
Are there exceptions for small words at the end of titles?
OSCOLA focuses on major vs. minor words, not position, so don’t capitalize a minor word like “of” just because it’s last. Capitalize only if it’s major or starts the title/subtitle, unlike styles like Chicago that always cap the final word.
Conclusion
Good OSCOLA title capitalization is mostly about one rule applied with care. Capitalize the major words, keep minor linking words lowercase, and give the first word of any subtitle a capital.
Mastering OSCOLA title capitalization ensures clean consistency in your bibliography, table of cases, and table of legislation. For subsequent citations, using the short title and year requires precise handling of titles from the first mention, especially with secondary sources. Once you stop borrowing rules from other styles, your legal citation looks more consistent at once. That’s the real test of OSCOLA title capitalization: clean, predictable titles that read like law, not guesswork, paving the way for academic success.
