What is copy-editing? What does a copy editor do? Well, copy-editing involves making far more changes to a piece of writing than proof-reading does. The work is more creative. A copy editor's job is to prepare the text as well as possible without rewriting it (substantive editing or copy writing) or making changes that are out of keeping with the general style of the work. This is editing for sense, and takes in clarity, choice of words, grammar, organisation, and structure, as well as libel and safety.
I will copy-edit your article, your book, or your essay, quickly and accurately. Working with editors and proof-readers on both sides of the Atlantic means that there really is no job too large or too small, nor any subject I cannot tackle, in British or American English. Any level of edit is available, from substantive editing (rewriting of text), to copy-editing (improving style and structure), to proof-reading.
