If your article or book has been commissioned, your publisher will edit it for you it as part of the publishing process, so you don’t need to enlist the services of an editor yourself.
However, if you are submitting work ‘on spec’, it is essential that it creates a good impression. Competition for space in publications is always fierce, so your copy must be as clean as possible, consistent in its voice and argument, correctly presented and fully referenced.
