ColoringBook.com opens national book submission program

Really Big Coloring Books has launched a national submission portal for authors, illustrators, educators and independent publishers to get completed books reviewed for possible listing, sale and distribution. The St. Louis company says reviews can take up to 60 days and submission does not guarantee acceptance or transfer of rights.

Why it matters: - The program gives independent creators a new path into national sales and distribution channels tied to ColoringBook.com and Really Big Coloring Books’ broader network. - The effort could help smaller publishers and solo creators reach a larger audience without building their own distribution infrastructure.

What happened: - Really Big Coloring Books, Inc. launched an online national book submission program for creators to submit qualifying books and creative work for review. - The company is based in St. Louis and was founded in 1988. - The submission portal is open to authors, illustrators, educators, independent publishers and content creators. - Creators can submit completed coloring books, activity books, educational books, storybooks, children’s books, specialty publications and general-interest books. - The company said submitted titles may be considered for listing, sale or distribution through ColoringBook.com and other RBCB sales channels.

The details: - Applicants must provide publisher and contact information, book title, author and illustrator credits, ISBN, publication date, language, binding and other product details. - RBCB may also request a cover letter and a complete PDF or physical review copy. - Submitted books must be original, properly licensed and controlled by the submitting person or organization. - Illustrators can submit sample artwork or links to online portfolios. - Coloring-book artists should show clean outlines, closed shapes, open coloring spaces and age-appropriate subject matter. - Creators must disclose any AI-generated or AI-assisted content. - RBCB will review submissions for originality, quality, audience suitability, production standards and marketplace potential. - Reviews may take up to 60 days. - Submission does not guarantee acceptance, publication, listing, sale or distribution. - Submitting material does not transfer ownership or publishing rights to RBCB. - Creators can review the guidelines and submit material through the book submission portal.

Between the lines: - RBCB is positioning itself as both a publisher and a distribution partner, which could appeal to creators looking for a lower-friction route to market. - The explicit requirement to disclose AI-generated or AI-assisted content shows the company is setting review standards around originality and production methods. - The 60-day review window suggests the program is meant to be selective rather than an open intake funnel.

What's next: - Creators and publishers can submit completed work for consideration now. - RBCB will continue evaluating submissions and may move selected titles into listing, sale or distribution channels. - Accepted creators will still retain ownership and publishing rights unless they separately agree to other terms.
