I made a video yesterday on Copyediting, and the difference between copyediting and proofreading. In this (unedited, lol!) video, I also mention what proofreading is. I cite a website’s definition of what these important jobs are, and what professional copyeditors are for.
Now, I don’t claim to be the world’s best expert on copyediting. But if I can answer anyone’s questions on the subject, I’d sure like to try, or at least I’ll find the answer.
Here’s the video.
