Each reference should use the elements, punctuation and format shown in the source examples with instructions (linked on this page, or, use the drop down menu under the tab for this page).
Note: PDF is a format not a source type, so you need to identify what source the PDF is.
- At the end of a piece of work add a list of references to sources cited in the text. This list may be titled ‘References’ or 'Bibliography'. See What is the difference between a reference list and a bibliography? for an explanation.
- In the Harvard system, all references are listed in alphabetical order by author name in a single list. The only exceptions are when citing unpublished sources and legal materials, which should be listed separately after the main list of sources.
- Check your Faculty's handbooks or ask academic staff for clarification, if necessary.
