How do you cite sources? You probably had this lesson in high school or college, so I hope you don't mind if I clarify for those who fell asleep during those sessions.
You state the place from where you quoted or paraphrased a source. Then you provide bibliographic information. Most publishers ask you to cite from print or the Internet. If the latter, you provide the following information:
* The book (or magazine). We put titles of books and magazines in italics but the titles of chapters or articles in quotes.
* The author.
* The publisher.
* The city, date, and year of publication.
* The page you quote.
I suggest you make photocopies of everything you quote so you can send them to your publisher. Your copyeditor may not have those same books or might have to write back and ask you to send it. You send them three pages: the title page, the copyright page, and the page from which you quote. If you highlight the text, you make it easier for the copyeditor.
There are slight variations among publishers, but this will work: Unleash the Writer Within by Cecil Murphey (OakTara Publishers, 2011), p 88.
