The Harvard Solent referencing scheme requires that when you quote directly or paraphrase from a source that includes page numbers, then where the source provides page numbers, the in-text reference must include page number(s).
Page numbers are included in the in-text reference if you have used a direct quote, paraphrased and you want to direct the reader to a specific page or pages. When you are including a page number a comma is used after the date e.g. (Smith 2013, p.16).
You must include the specific page using p. where the quote or paraphrased text is within a specific source. In this example, using a direct quote from a source: e.g. It is essential that students "reference with care" when writing their assignments (Smith 2013, p.45).
For multiple pages you can identify a page range using pp. for example when the quote or paraphrased text runs across two pages in a specific source. In this example, paraphrasing text from a source: e.g. It has been stated that all resources used to support your arguments must be included in your reference list (Smith 2013, pp.16-17).
If you are summarising a large section or the entire work, you do not need to include a page number.
If the information you need is on non-consecutive pages, you should still cite all of the relevant pages. Use "pp." before the page numbers. For example, if the information started on page 30 but then continued on page 35, you would write (Taylor 2015, pp. 30, 35). Use a comma between non-sequential page numbers.
