Question

If I am referencing a book that is referencing another source, how do I cite it in text for APA?

Answer 1

If the book tells where they got the information from, I'd cite that source, not the book. (;

Look around on the Purdue owl site, really helpful! I think you are looking for indirect citation help which is on the link I sent.
