Copy editing is the process of revising written material ("copy") to improve quality and readability, as well as ensuring that a text is free of errors in grammar, style and accuracy. The Chicago Manual of Style states that manuscript editing encompasses "simple mechanical corrections through sentence-level interventions to substantial remedial work on literary style and clarity, disorganized passages, baggy prose, muddled tables and figures, and the like ". In the context of print publication, copy editing is done before typesetting and again before proofreading. Outside traditional book and journal publishing, the term "copy editing" is used more broadly, and is sometimes referred to as proofreading; the term sometimes encompasses additional tasks.
