The OSCOLA system of referencing uses footnotes.
The following should be included in your work:
Superscript number (1, 2, 3) in the text of your work together with footnotes
Bibliography containing a structured list of any primary and secondary sources used.
The Bibliography should be structured with primary sources listed first then secondary sources using relevant headings. For example:
Table of Statutes (by jurisdiction, if appropriate)
Table of Cases
Journal Articles
Books
Websites
