Question

So, I am writing an essay for my college class. I would like to quote/cite from my textbook in mla format. However, the quotes are from an extract from another book, my textbook is only featuring part of another book. Should I cite the textbook, or the book the excerpt was taken from?

Answer 1

You can cite the textbook, but when you are introducing your quote in your paper you should mention that the textbook author is quoting someone else.
