Editors edit "copy" for grammar, spelling, and punctuation; we also check for consistency of presentation and facts. Editors usually come into the picture after the author has self-edited or had their peers review their work.
Editors can also do the following:
- substantive editing - clarifying and reorganizing the content and structure of a manuscript;
- stylistic editing - clarifying meaning, eliminating jargon, and smoothing language;
- rewriting - creating a new manuscript or part of a manuscript from information supplied by others.
