In the Washington Post, I ran into a Letter to the Editor from a person who was interviewed for an article. According to the letter, the individual stated a particular way some people typically behave and that the person he was talking about was not among those people. When the quote was edited into the story, the quote was edited in such a way, it looked like he had said this person acted that way.
The Lakeland Library’s Evaluating Sources reminded me of that. Though it’s for research papers, it’s still handy resource for writers. The file gives criteria about evaluating research sources and detecting bias. It also has an list of links for more information, including links from Berkley and Cornell.
Right now, I’m working through both Holly Lisle’s How to Revise Workshop and Writing Sideways.
