 How can we reference an author's ideas without actually reading that author's work? Let's say you're reading this book by Stuart and Saren for your marketing assignment. In it, the authors refer to ideas written by another author. You would like to use Feldwick's ideas in your assignment. Ideally, you should read his article, published in 1996. But you can't find his article. Although we haven't read it, there is a way we can still include this second author's ideas without plagiarising. It's called a secondary citation. To do this, we cite Feldwick in text but add the words as cited in before the first author's name. We can do it like this or this. We only include the publication date of Stuart and Saren's book and not the date of the article written by the secondary author, Feldwick. The secondary citation, Feldwick, does not appear in the reference list. Put Stuart and Saren's book in your reference list because this is the one that you actually read.
