Proofreading is one of the final hands-on stages of the publishing process. At proofreading, the manuscript will receive a final read through. According to the University of Chicago Press’s (2010) The Chicago Manual of Style (Sixteenth edition), “Proofreading is the process of reading a text and scrutinizing all its components to find errors and mark them for correction.” All components encompasses more than reading the text. Proofreaders should also the following.

• Verify the table of contents’ accuracy: One of the first things readers will see (and use) is a book’s table of contents (TOC). If it’s incorrect (for instance, it says chapter 2 begins on page 13 but it actually begins on 31), the author’s and publisher’s credibility will be damaged. Readers may ask, “If these people can’t even get a page number correct, what else have they got wrong?”
• Double check the spelling of proper nouns: Ideally, this should have been done by the author and editor. Yet, oversights do occur; but they don’t have to occur on the proofreader’s watch. Again, obvious mistakes (like misspelling an author or organization name) damage the author’s and publisher’s credibility.
• Check the accuracy of section headings and running heads: “Running heads—the headings at the tops of pages—function, like page numbers, as signposts” (University of Chicago Press, 2010). Pages shift or figures, tables, or lists are moved during formatting. When this happens, the running head or section headings may no longer reflect the page’s content.

Happy proofreading!
