Generally, to avoid this, I do not quote quotes from a book. I write something like ‘In Simone’s reading of Nomad’s views on pedagogy, specificity is positioned against generalization of conceptual frameworks. She writes, ”....” (...., pg.)’ so that you only quote the author not the author’s quote of another author. You can go one step further and do a deeper paraphrasing of the quote used by the author and then paraphrase or directly quote what the author said about the quote. I suppose I also sometimes fake that I have the actual original book out of which that quote came from and I put that source as citation.
