the person employed in a publishing house who works on the detail of a book, ensuring accuracy and completeness and preparing it for typesetting
Someone who helps prepare material for publication Copy editors find and correct mistakes in grammar, spelling, and usage (is this the right word to use for what you're trying to say here?) They also try to ensure consistency (if the hero has red hair on page ten, does he suddenly appear as a blond on page 245?) and completeness (do the questions raised on the first page ever get answered?) And, finally, copy editors help style the work so that it conveys the message intended by the author
