I found this to be very helpful!

“Quotes give a human voice and flavor to the article and gives the reader a break from “just the facts.” It’s not enough to have a quote, the quote has to contribute something more to the article than just confirming information.

Quotation marks should only be used around a direct quote. When you use those symbols (”,”) you are telling the reader that this is exactly what the person said. Make sure your notes and recordings are accurate. This is what gets writers and journalists in trouble and then shakes the public’s confidence in what they read.”

More great tips to come!
