A proofread is designed to be the final onceover before you press the ‘Publish now!’ button. It’s where the fine details of the formatting or typesetting are checked — the term literally means ‘the reading of the proofs’, where ‘a proof’ is a page that has been typeset ready to be sent to the printer. A proofread also provides a last chance to correct any errors that haven’t been picked up during the edits or revisions.
I don’t offer a proofreading service because my expertise is in providing editorial support at an earlier stage in a book’s gestation. I specialise in edits that focus on a book’s structure, content and language.
