How do I cite a source quoted in another source?
Answer
You're reading source A and it has a really excellent quote from source B. It's so good, you want to use that source B line in your paper. How do you tell the reader?
It's called an indirect citation, and each citation style (APA, MLA, Chicago, etc.) handles this a little bit differently. All of the styles recommend or strongly encourage or expect you to go check source B yourself, to read around it and make sure they say what you thought they said. Then source B goes into the list just like any other.
But sometimes, getting source B isn't possible. If you're using MLA , you can write "qtd. in [source A]" for your in line citation and then put only source A in your Works Cited list. If you're using ALA, you'll write "B, as quoted in A" for the in-line citation, and put only source A in your reference list. If you're using Chicago Manual of Style, you should give the bibliographic data of both works in the note and the bibliography, "source B, quoted in source A ". You can read more about this on our citation guide, or check out the manuals themselves.
