When you read about someone's idea in a book or article, and you also want to cite that idea in your work, you should make the effort to try to locate the original source yourself, using the book or article's reference list and Library Search. If something is so relevant that it is worth citing in your own writing, we recommend reading the original first-hand, rather than second-hand. 

Sometimes, citing something second-hand - called secondary referencing - is unavoidable. This may be because the original source is not available, out of print, even in a different language. In these cases you would need to:

  • cite in your writing both the original source, and the source you've read which cites that idea or quote; and
  • fully reference in your reference list only the source you've actually read, not the original source.

The way in which you present a secondary reference in your work depends on the referencing style you need to use. For example, Cite Them Right shows that secondary references in Harvard style might look like this:

Harvey (2015, quoted in Lewis, 2016, p.86) provides an excellent survey…

White’s views on genetic abnormalities in crops (2014, cited in Murray, 2015) support the idea that…
