(Double-checking line and copy edits)
Proofreading is the final step in the editing process and results in the final “don’t-touch-it” draft. This is where The Next Chapter can help catch spelling mistakes, typos, missing words, and isolated punctuation errors overlooked during copy editing or introduced during the formatting process. If you wish, your manuscript can also be cross-checked against previous drafts to ensure that earlier changes were made correctly, and that formatting elements such as heading and typeface styles, page numbers, etc. are appropriate and correct.
As I previously mentioned, “Proofreading” is often lumped in with “Copy Editing,” but I consider it a process of its own. The purpose of proofreading is for double-checking, not assessing or improving, and is the step that requires the most attention to detail.
