What Should You Include When Submitting a Book to a Publisher?

Finishing a book is a major achievement, but preparing it for submission requires a few more steps. Publishers need to understand what your book offers, who it is written for, and whether it fits their catalogue.Before submitting your manuscript, prepare the required documents and check the publisher's guidelines. Requirements vary depending on your genre and whether you are approaching a traditional publisher, literary agent, or publishing service.What Should You Include in a Book Submission Package?1. A Complete or Requested ManuscriptYour manuscript is the main part of your submission. Many fiction publishers expect a completed novel, while others request sample chapters first. Nonfiction publishers may consider a proposal before the full manuscript is finished.Check the submission guidelines before sending your work. Format the manuscript with a readable font, consistent spacing, clear chapter breaks, and page numbers unless the publisher specifies otherwise. Proofread it carefully to correct spelling mistakes and formatting issues.2. A Clear Book SynopsisA synopsis summarizes your book and helps the publisher understand its content without reading the entire manuscript.For fiction, include the main character, central conflict, important developments, and ending. For nonfiction, explain the central idea, main topics, and what readers can learn.Keep the synopsis focused and follow the publisher's requested length. Avoid turning it into promotional copy or leaving out important details to create suspense.3. A Book ProposalA book proposal is particularly important for nonfiction. It explains the book's purpose, intended audience, and potential place in the market.Depending on the publisher's requirements, include a book overview, chapter outline, target audience, comparable titles, author biography, and sample chapters.For example, if you are writing a guide for freelance business owners, explain the problems it addresses and how its content helps readers. A clear proposal gives publishers a practical understanding of the book's purpose and scope.4. An Author BiographyYour author biography should highlight experience relevant to your book. Include professional qualifications, subject knowledge, previous publications, or other relevant achievements.Keep it concise. If this is your first book, focus on your background and knowledge rather than worrying about a lack of publishing experience.5. Sample Chapters and Target AudienceSample chapters allow publishers to assess your writing style, structure, and ability to engage readers. Submit the exact chapters or word count requested, ensuring they match the manuscript described in your synopsis.You should also identify your intended audience. Instead of claiming your book is for everyone, explain which readers are most likely to enjoy it or benefit from it.Comparable titles can help establish your book's market position. Choose books with a similar subject, genre, or readership, and explain how your approach differs.6. A Professional Submission EmailKeep your submission email brief and relevant. Include the book title, genre, word count, a short description, and any requested attachments.Use a clear subject line, address the appropriate recipient, and follow the publisher's instructions. Research the publisher before submitting to make sure it accepts your genre and type of manuscript.Do Publishers Require the Same Documents for Every Book?No. Submission requirements vary by genre and publisher.Fiction: A completed manuscript, synopsis, and sample chapters are common requirements.Nonfiction: Publishers may request a proposal, chapter outline, audience details, and sample chapters.Poetry: Some publishers accept individual poems, while others require a complete collection.Children's books: Requirements depend on the format. Some picture-book publishers prefer text-only submissions rather than finished illustrations.Literary agents may have different requirements from publishers. Always check the recipient's official guidelines before sending your materials.Common Book Submission Mistakes to AvoidAvoid these common mistakes when submitting a book to a publisher:Ignoring submission guidelines or sending the wrong file format.Leaving out required documents.Writing an unclear synopsis or incomplete proposal.Attaching unnecessary files.Sending generic emails without researching the recipient.Paying for publishing services without understanding the costs, contract, and deliverables.Before submitting, open every attachment and confirm that your documents are complete and consistent.What Happens After You Submit Your Manuscript?The publisher may first check whether your book fits its catalogue. If it passes the initial review, an editor or reader may assess the writing, structure, and potential audience.Possible responses include rejection, a request for additional material, or an offer to discuss publication. Waiting times vary, so follow the publisher's stated response period before sending a follow-up.A rejection does not necessarily mean your book is poorly written. The publisher may not be accepting your genre or may already have a similar title. Consider any feedback before revising your manuscript or approaching another publisher.Should You Submit Your Manuscript or Use a Book Publishing Service?Traditional publishing and paid publishing services serve different purposes. Traditional publishers consider manuscripts for publication under an agreement. Publishing service providers generally charge for work such as editing, formatting, cover design, or publication assistance.Before hiring a provider, confirm what the price includes. Review the contract, publishing rights, royalties, distribution arrangements, and additional fees. Paying for publishing services does not guarantee traditional publisher acceptance or strong sales.How Bookslake Can Help Prepare Your Book for PublicationAuthors who need help preparing their books can review Bookslake's book publishing services.
