TIPS FOR GENERAL USE OF OSCOLA

• OSCOLA uses very little punctuation. There are no full stops after abbreviations. There are no full stops after the v between the party names. Footnotes should be closed with a full stop.
• Where more than one citation is given in a single footnote reference, separate
  them with semicolons
• Commas are used for specific purposes. Commas are used to separate distinct parts of a book reference, notably between the author and the title. They are used between the neutral citation and the law report citation in cases.
• In footnotes, the author’s first name or initial precedes their surname; in
  bibliographies, the surname comes first, then the initial, followed by a comma.
• Titles of books and similar publications are italicized. All other titles should be in single quotation marks. The first letter of all major words in a title should be in capitals.
• Pinpoints to parts, chapters, pages, and paragraphs come at the end of the
  citation. If citing a chapter or part and page number, use a comma before the
  page number.
• If you source a publication online which is also available in hard copy, cite the
  hard copy version.
• Publications that are only available online should end with the web address in angled brackets < > followed by the date of the most recent access.
• Colons are used to separate a title from a subtitle, as in the following example
  Competition Law: Precedents and Procedures
• Case names should be in italics and in lower case (other than titles) including the ‘V’.
• In the case of reporting, the date should be in round or square brackets according to the style of the law report series.
• Acts should be cited by their short title, using capitals for the major words.
