Citation, Documentation of Sources

Q. I am doing some developmental editing on a book about Elvis and East Tupelo, Mississippi. The author has gathered her information from a variety of sources, including firsthand interviews. Footnotes and a bibliography will not work with the format. How do we acknowledge sources such as websites or newspapers?

A. If you absolutely can’t have notes (not even endnotes? or a brief section called “Sources”?), then you have to write the sources into the text. That could get ugly. It’s one reason notes were invented.
