At the end of your work and after any appendices, you need to provide a structured list of all the sources you have used. This does not include any background reading and you should only list each source once, even if you have referred to it multiple times.
The Bibliography includes:
All primary sources you have used with headings, which could include Cases, Legislation, Treaties.
All secondary sources you have used with headings, which could include Books, Book chapters, Journal articles, Official publications, Websites.
Unlike footnotes, references in the Bibliography do not have a full stop at the end.
