Q. How do I cite a source that is quoted in another source?

NoodleTools (a bibliographic citing source) says the following:

Scenario: You have read a journal article written by John Smith. In the article, John Smith quotes Jane Adams' book Chicken Little (which you have not used in your own research). You would like to quote Jane Adams in your own paper.  MLA encourages you to find the original source and cite Jane Adams directly, since it helps you evaluate whether John Smith has accurately quoted and represented Jane Adams' ideas.  However, if you don't have access to Chicken Little, you'll need to use an indirect reference (MLA 6.4.7).

Instructions:

1. Include an entry for the source you have in hand (in this case John Smith's journal article) in your reference list.
2. In your parenthetical (in-text) reference after the quote, credit the original source (in this case the Chicken Little book) adding the words "qtd. in" to show that your got the Adams quote from Smith and didn't verify it independently.

Here's how your indirect in-text reference will look:

...Adams asserts in her book Chicken Little that "without a doubt, the chicken came before the egg" (qtd. in J. Smith 21).
