Book Proofreading
Book proofreading for authors who are almost there. We read your edited manuscript or typeset proof line by line and catch the typos, slips and layout faults that survive every earlier round of editing.
Proofreading that catches what everyone else missed
Proofreading is the final quality check on a book, not a rewrite. By the time a proofreader sees your pages, the story or argument should be settled and the sentences should already read well. Our job is to find what is still wrong: the missing word, the doubled "the," the comma in the wrong place, the chapter title that changed halfway through the table of contents.
There are two moments when a book can be proofread. One is the clean, edited manuscript in Word, before design. The other is the typeset proof, the PDF your designer produces after interior formatting. The second matters more than most authors expect, because layout introduces errors of its own: bad line breaks, stray widows, wrong running heads, page numbers that skip. A proofread at that stage protects the version your readers will actually hold.
We proofread to the Chicago Manual of Style, 18th edition, which most US book publishers follow, plus Merriam-Webster for spelling. If you or an earlier editor already built a style sheet, we follow it to the letter. If not, we create one, so every later reader (and your next book) applies the same choices.
Proofreading is the last stage of our book editing service. If your draft still needs structural work, developmental editing comes first. If the sentences need tightening and the facts need checking, line and copy editing does that job. We will tell you honestly which stage your book is in, even if the answer is not proofreading.

How book proofreading works, from clean manuscript to approved proof
A good proofread is methodical, not magical. Here is what happens to your pages, what a proofreader looks for, and how to plan the stage so it actually catches errors.
Proofreading a manuscript versus proofreading typeset pages
A manuscript proofread happens in Microsoft Word with tracked changes. It suits authors who will publish a simple eBook first, or who want the text as clean as possible before handing it to a designer. Every correction is visible, and you accept or reject each one.
A proof proofread happens on the designed pages, the modern version of galley proofs. We mark the PDF with comments and standard annotation tools, so your typesetter can find each fix by page and line. Nothing gets retyped from scratch, which is how new errors creep in.
Traditional publishers do both. For an independent author working to a budget, the typeset proof is usually the better single investment, because it is the version readers will actually hold. If we are also handling your interior formatting, the proofreader and designer work from the same file and the same style sheet.
What a proofreader checks on every page
The text layer comes first. That means spelling, including homophones a spellchecker happily accepts (their and there, discreet and discrete, peak and pique). It means punctuation, capitalization, missing or repeated words, and agreement slips left behind when a sentence was revised.
Then consistency. Is it Sergeant or Sgt.? Gray or grey? Nine or 9? Does the heroine's eye color stay the same in chapter 2 and chapter 22? Are dates, ranks, place names and dialogue punctuation handled the same way every time? Readers rarely notice consistency when it is right, and they notice immediately when it is not.
A proofreader queries rather than rewrites. If a sentence is confusing or a fact looks wrong, we flag it for you instead of silently changing your voice. At this stage the goal is fewer changes, made precisely.
Layout checks: widows, orphans, running heads and page numbers
On typeset pages a second checklist begins. We look for widows and orphans, the single lines stranded at the top or bottom of a page, along with very short last lines and loose lines with wide word spacing that make text look patchy.
We check end-of-line hyphenation, so words break where the dictionary allows and you do not get three hyphens stacked down the margin. We confirm that running heads carry the right book and chapter title, that page numbers (folios) run in sequence, and that chapter openers start on the correct page.
Front and back matter get their own pass. The table of contents must match the real chapter titles and page numbers. The copyright page, dedication, acknowledgments, captions, cross-references and any index entries are checked against the pages they point to. These are the errors reviewers screenshot, so we treat them as seriously as the text.
Notes, tables, captions and indexes in nonfiction
Nonfiction carries extra machinery, and each piece is a place for errors to hide. Note numbers in the text must match the notes at the back of the chapter or book. Bibliography entries should follow one consistent format. Table headings, units and totals need to agree with the text that discusses them.
Captions are a classic trouble spot. A photo gets moved during layout, and suddenly the caption says "above" when the image now sits below, or figure 7 is called figure 6 in the text. We check every caption and cross-reference against the page it actually lands on.
If your book has an index, we spot-check entries against the final page numbers, since an index built from an earlier proof can drift by a page or two. Field manuals, technical guides and military history titles tend to have the most of this apparatus, and they get the most attention.
The style standard and your style sheet
The Chicago Manual of Style is the reference most American trade publishers use, and its 18th edition, published in 2024, is the current one. It settles questions like the serial comma, when to spell out numbers, how to treat titles and how to punctuate dialogue. Its published list of proofreaders' marks is still the shared language between editors and typesetters.
Chicago is a default, not a cage. Fiction, memoir and technical books often make deliberate choices of their own: invented words, regional dialect, military abbreviations, a specific way of writing measurements. Your style sheet records those choices so the proofreader enforces your book's rules, not a generic one.
When we finish, you get the updated style sheet back. It saves time and money on audiobook scripts, translations and the next book in a series.
One pass or two?
A single careful pass catches most errors. Two passes catch noticeably more, especially on long books, because every reader goes partly blind to a text after enough hours with it.
Our standard approach on typeset proofs is one full proofread, then a check of the corrected pages to confirm each fix went in cleanly and did not knock a line onto the next page. For long nonfiction, books with complex tables or illustrations, or any project where a reprint would be painful, we recommend a second full read by a different proofreader who has never seen the text.
We will recommend what your book needs and price it into the same fixed quote, so the decision is about quality, not a surprise bill.
Why proofreading should come last
Every time text changes, it can break. A rewritten paragraph can introduce a fresh typo, and on a typeset page it can push a widow onto the next page or change every page number in the table of contents. That is why proofreading pays off only once the content is final.
The order we recommend is developmental edit, then line and copy edit, then design, then proofread the typeset pages. Our article on editing stages explained walks through each step. Proofreading earlier is not wasted, but if you plan to keep revising, a cheaper copy check now and a real proofread later is the smarter spend.
Proofreading also sits right before publishing. Once the proofs are approved, files go to the printer or retailer, so this is the cheapest moment to fix anything you would hate to see in a reader review.
What proofreading cannot fix
A proofread will not repair a sagging middle, a confusing argument or flat dialogue. Those are editing problems, and asking a proofreader to solve them leads to either a frustrated author or a proofreader overstepping the brief.
If our sample shows that a manuscript has recurring grammar issues on most pages, we will say so and suggest a copy edit first. It is a cheaper outcome for you than a proofread that marks hundreds of changes and still leaves the prose rough. When the text is ready, the proofread is fast, focused and worth every hour.
eBooks, audiobook scripts and the second format
Reflowable eBooks need their own spot check. Line breaks move with screen size, so we focus on the things that survive conversion badly: links in the table of contents, footnotes and endnotes, scene break markers, italics and special characters. Our KDP guide covers how Amazon previews and delivers those files.
Audiobook scripts are proofread for the narrator, not the eye. We flag pronunciation questions, spell out ambiguous numbers and abbreviations, and note anything that only works visually, like a table or a footnote. It is a natural step before audiobook production.
How to get the most from your proofreader
Send the final version. Every change you make after proofreading starts the risk over, so lock the text first. Check your length with our word count checker so the quote matches the file.
Share whatever exists: the style sheet, a list of character or place names, preferred spellings and any glossary. Tell us which corrections you want made directly and which you want queried. Then review our changes in one sitting rather than piecemeal.
You can read more about deadlines, communication and payments on our how we work page. The short version: a fixed quote, one point of contact, and you keep 100% of the rights to your book.

Proofreading FAQ
Editing improves the writing itself: structure, clarity, flow and accuracy. Proofreading comes after editing and looks for the errors that remain, such as typos, missing words, inconsistent spellings and layout faults on typeset pages. A proofreader makes small, precise fixes and asks questions instead of rewriting. If your book has not been edited yet, a proofread alone will not fix weak sentences or plot problems.
Most book proofreads take about one to three weeks. A 70,000-word novel with clean text sits at the shorter end, while long nonfiction with notes, tables or an index takes longer, and a second full pass adds time. Tight deadlines can sometimes be met if you tell us early. We confirm the schedule in your fixed quote so you can plan your launch around it.
Ideally after. Typesetting creates its own errors, including bad line breaks, widows and orphans, wrong running heads and page numbers that no longer match the table of contents. Proofreading the typeset proof catches those along with the text errors. Some authors also proofread the manuscript before design, which keeps correction rounds short. If you can afford only one, proofread the final typeset pages.
Yes. Many authors order a printed proof copy and want a professional read before approving it. We work from the matching PDF so corrections can be marked by page and line, and we note anything visible only in print, such as margins too close to the gutter. Your designer or our formatting team then updates the files before you reorder a final proof.
One careful pass catches most errors, and it suits many novels and memoirs. Two passes, ideally by different proofreaders, catch noticeably more and are worth it for long books, technical or heavily formatted nonfiction, and any title where a reprint would be costly. We recommend the right number for your book in the free consultation and include it in the fixed quote.
Grammar software is useful for a first sweep, and we encourage authors to run one. It still misses real-word errors, inconsistent names and spellings, wrong facts, dialogue punctuation in fiction, and every layout problem on a typeset page. It also suggests changes that flatten an author's voice. A human proofreader understands context and your style choices, which is what a published book needs.
We follow the Chicago Manual of Style, 18th edition, which is the standard for most US book publishing, and Merriam-Webster for spelling. Where your book has its own conventions, such as dialect, invented terms, military ranks or units of measure, we follow your style sheet first. If you do not have a style sheet, we build one during the proofread and give it to you.
No honest proofreader promises perfection. Even books from major publishers ship with the occasional typo. A professional proofread catches the large majority of remaining errors, and a second pass catches more. You can help by sending only final text and avoiding new revisions after the proofread, since every late change is a fresh chance for a mistake.
We give a fixed quote after a free consultation and sample. The price depends on word count, whether we are proofreading a manuscript or typeset proofs, how many passes you want, and how complex the layout is. Notes, tables, captions and an index add time. You know the full cost before work starts, and there are no hourly surprises at the end.
Yes, and we recommend it. The back cover blurb, spine text, author bio and any review quotes are the first words a browsing reader sees, yet they are often written last and checked least. We proofread cover text against the interior so the title, subtitle and author name match everywhere, including the spine and the copyright page.
