  • Does Manuscript Mentoring's Book Editing service really include both developmental editing and line editing? Other editing companies split these services.
    Yes, our Book Editing service includes both developmental editing and line editing. If you place a Book Editing order, the clarity, grammar, syntax, punctuation, spelling, and flow of every sentence will be checked. The book’s structural elements (characterization, plot, pacing, suspension of disbelief, etc.) will also be analyzed and critiqued. Other editing companies tend to split these services so that they can charge more.
  • What exactly is the difference between developmental editing and line editing?
    Developmental editing (also known as substantive editing) focuses on the big picture of a book, addressing structural issues, plot development, characterization, pacing, and overall coherence. It involves substantial revisions and suggestions to improve the content and organization of the work. Line editing (also known as copyediting) focuses on sentence-level improvements, enhancing clarity, flow, style, grammar, and syntax. It ensures consistency, removes redundancies, and refines the language.
  • Which genres do you edit?
    All genres except erotica.
  • Do you edit only fiction?
    No, we edit both fiction and narrative nonfiction (memoirs, biographies, travelogues, historical narratives, etc.).
  • How are files sent and received?
    Files are sent and received via email. In the rare instances where a file is too large to email, we use Dropbox, Sync, or WeTransfer (whichever is more convenient for the customer).
  • Which file types do you handle?
    We edit DOC, DOCX, DOCM, RTF, PDF, ODT, and FODT file types.
  • How do customers pay?
    A PayPal invoice is sent to your email address after you place your order. Please note that you do not need to have a PayPal account to pay a PayPal invoice. For more information on PayPal, please visit their help center.
  • Will anyone besides Manuscript Mentoring see my work?
    Absolutely not. We take the privacy of our clients seriously. For more information, please see our Privacy Policy.
  • Does any part of my intellectual property transfer to Manuscript Mentoring when I use any of the company’s services?
    No, your work stays your work. We offer set services for set fees—nothing more. You shouldn’t make use of any editing, proofreading, or formatting firm that requires the transfer of intellectual property.
  • Is Manuscript Mentoring affiliated with any publishing house or literary agent?
    No, we are not.
