Proofreading is merely reading the text without suggesting any significant error or oddity. It confirms that your document is ready for publishing taking care of minor mistakes and formatting issues. Ensure you only opt to proofread after the manuscript has gone through the previous major editing phases like copyediting or line editing. A professional editor won’t recommend proofreading an erroneous document.
Copyediting prepares your manuscript for proofreading. This includes in-depth correction of grammatical errors, punctuation, syntax flaws and word choice. A copyeditor may make rewrites to reduce colloquialism and redundancy, improving consistency.
