High Quality Content by WIKIPEDIA articles! Copy editing (also written as copy-editing or copyediting, and sometimes abbreviated to ce) is the work that an editor does to improve the formatting, style, and accuracy of text. Unlike general editing, copy editing might not involve changing the substance of the text. Copy refers to written or typewritten text for typesetting, printing, or publication. Copy editing is done before both typesetting and proofreading, the latter of which is the last step in the editorial cycle.
