When to include page numbers
You should include page numbers if you quote directly from the text, paraphrase specific ideas or explanations, or use an image, diagram, table, etc. from a source.
Example:
"It was emphasised that citations in a text should be consistent" (1, p.24).
When referencing a single page, you should use p.
For a range of pages, use pp.
Example:
p.7 or pp.20-29.
If the page numbers are in Roman numerals, do not include p. before them.
Example:
(5, iv)
