Multiple pages from the same source, or a quotation that breaks across pages
Answer
Each separate quotation or paraphrase that you use should have its own citation. In your work, it is normal to have lots of in-text citations for the same source, each with a different page reference.
When you summarise a source, or a general idea that is discussed in the whole text of a source, you do not need to use page numbers at all. In these cases, the in-text citation will not have a page reference. (Remember that all sources will still need to have a reference list entry!)
Example
Another article explores the theme of childhood in Coleridge's work (Wu, 2012).
There are two instances where you may need to put either a page range or several page numbers in your in-text citation.
Scenario 1
When an idea you are paraphrasing is explained in more than one place in the text, or you are connecting two related ideas from the same text into one paraphrase, you can put all of the page numbers you have used and separate them with a semicolon (;).
Example
Standard Romantic conceptions of free-spiritedness and innocence in childhood lie in stark contrast to the images of new life presented in 'London' (Davies and Patel, 2003, p.23; p.28).
Scenario 2
Where an idea you are quoting or paraphrasing breaks across pages (i.e. at the bottom of one and the top of the next), you can use the page range in your in-text citation.
Example
What counts as 'encouragement' and 'prompting' in user testing is a difficult matter to judge (Barnum, 2012, pp.221-222).
You should always use the full page numbers when giving a page range. In the example above, it would have been incorrect to use "pp.221-2".
