I love reading and editing my manuscript on my computer. I can edit as I go along without having to go back to it later. Problem is, even after reading and editing my manuscript a dozen times onscreen, I could still miss typos, bad breaks, and other mistakes.
Just like reading your manuscript out loud, there is something helpful about editing your work by reading a hard copy of your manuscript. Seeing what you wrote on paper helps you see mistakes that you might have missed onscreen.
To save on trees, I only do this exercise after I’ve edited quite a bit onscreen.
If you haven’t tried reading your manuscript on paper, try it.
