How to MLA Cite an Excerpt of a Book That's in a Text Book
Sometimes, a textbook will quote an excerpt of another book or novel that you would like to reference in your paper. MLA style outlines specific guidelines for citing a source within a source, but, when possible, it is better to locate and cite the original source.
Citing an Excerpt

If you don't have the time or means to find the original source, you should include the textbook in which you found the excerpt on your "Works Cited" page.
