The crucial final step in the editing process—and the last check before publication—is proofreading. While line editing and copy editing can significantly alter the language of the document (such as fixing inconsistent spelling or hyphenations), a proofreader’s job is largely about quality control. Editing, rewriting, or deleting should not be done during the proofreading process. The proofreader will look for capitalization mistakes, misspellings, punctuation faults, verb tenses, and a variety of other grammar mistakes.
