Editing involves carefully reviewing a document to improve clarity, organization, flow, accuracy, and impact. It is important to ensure the writing says what is intended in a simple, straightforward, and logical manner. Editors should check that all key points are clearly illustrated without unnecessary words, digressions, or information not needed by the reader. The tone should be positive and flow easily even with complex topics. Proofreading focuses more narrowly on catching spelling, grammar, punctuation, and formatting errors to create a polished final draft.
