Nonfiction Editing

Why Nonfiction Authors Need Editing

We offer specialized editing services for nonfiction authors and other publishers of nonfiction, memoir, and general interest. Our authors typically write essays, opinion pieces or criticism, blog posts and website content, as well as book manuscripts for independent or popular presses.

Whether this is your first attempt or you’re well published, you need a trusted professional to give you feedback and to serve as your second pair of eyes. Flatpage offers high-quality editing with a fast turnaround and unlimited availability!

Our editors have PhDs in various subject areas, as well as specialized training and/or years of experience as manuscript editors. Many of our editors have published their own books and articles, including online and with renowned publishers.

Our professional editors help nonfiction authors in the following fields (and more!):

Fine Art & Art History



Film & Media

Manuscript Editing Services

Developmental / Structural Editing

Developmental editing will help you shape the content of your document so that your contribution takes center stage. Our developmental editors have served as editors of journals and acquisitions editors at presses, and published widely. We can help you shape the argument, organization, and flow of your manuscript.

Line / Stylistic Editing

Line editing is used to address the style of your writing so that it has maximal impact. Our line editors are experts at the craft of writing and have published widely themselves. We can help you maintain a consistent tone, improve word choice, identify text to be cut/pruned or expanded upon, and write clear sentences in native English.


Copyediting involves a rinse of your manuscript, with attention to grammar, punctuation, and mechanics (i.e., conforming it to house style or manual like the Chicago Manual of Style). Whether you’re an ESL writer or just need your manuscript formatted, this service will ensure that you deliver a clean document to your respective publisher or editor.


Proofreading is the final stage in the publication process and is reserved for minor typos and consistency between manuscript sections on page proofs. By the time you are ready for a proofread, your manuscript should have already gone through a content (developmental) edit and a copyedit. This service will ensure that your manuscript is publication-ready.


Note that the rates for developmental editing do not include front/back matter or citations/bibliographies.

Hear from Our Clients

Fellow authors who have worked with us share their experiences.

Tracy Stonestreet

“I was extremely impressed with the attention my project received, both in written comments and in my one-hour session with my editor! Leslie provided thoughtful, thorough, and actionable feedback. She worked through both the big ideas and the small writing tics, helping me see where I could easily improve my project. She was also very friendly and open, and seemed genuinely interested in my success. I would recommend this service to anyone who needs to get their writing to the next level.”

Ana Perry

“The manuscript assessment I received from Katherine Fusco was incredibly helpful and so generous. I am grateful to have had someone read my work so closely and to come up with practical paragraph by paragraph strategies for how to make my argument clearer as well as how to address big picture issues. The comments were clearly articulated in such a way that held my own writing accountable to the goals I claimed to put forward. Katherine also showed a breadth of knowledge of theorists like José Esteban Muñoz and was able to help strategize more effect use of theory throughout my text. While this was definitely an investment, the price is fair for the work especially if you are looking to get your writing to a broader audience and better place. I would 100% recommend these services to my friends and colleagues.”

Frankie Abralind

“I’m SO happy I hired Flatpage. I’m self-publishing my artist’s book, so pay-as-I-go editorial support has been an ideal solution. Cara made the whole experience super user friendly for me. Adam gave me incredibly valuable advice on layout, style, and content. Tim’s astonishing attention to detail revealed the subtlest errata that even my most fastidious friends hadn’t turned up. Tim even provided the unicodes for hard-to-type special characters! I’m so impressed and grateful. I’m sure I’ll hire Flatpage again for every book I ever write.”
