Editing skills are like muscles: you have to exercise them regularly, or they become flabby. Copyeditors don't have control over what rules they will need to apply to any given manuscript. Over time, rules that haven't been applied in a while become stiff with disuse. When you do try to apply one, you spend precious time looking it up and relearning it. At Copyediting, we're big believers in avoiding muscular atrophy. Successful editors keep their skills in peak condition. Regular reading, training, and practicing are keys to good editing muscle tone. Owned by Pilcrow Group Inc., Copyediting is a brand by and for copyeditors. Its mission is to create publications and training to support copyeditors throughout their careers.
