See, ISBN FAQInterior file RejectionsEbook - Contains Interactive ContentColoring books, journals, planners, puzzle books, etc. are not accepted because eBooks are not interactive in this manner.Ebook - Contains Workbook Style ContentEbooks should not include areas for writing e.g. fill-in-the-blanks, workbooks, or areas for notes.Ebook - English Only Only English-language eBooks are currently eligible for retail distribution. Bilingual eBooks are also not eligible at the moment.Ebook - Line BreaksYour ebook should not have incorrect line breaks throughout the book. Readers may think content is missing. Ebook - NCXAll EPUB ebooks use navigation built into the EPUB file to allow readers to move around in your book. This navigation is specified in the Navigation Control file for XML (NCX). Even if your book does not have chapters and therefore would not normally require a table of contents, it still must have an NCX. For example, a poetry book may not have “chapters”, but the individual poem titles could be added to the table of contents. See, How is the Table of Contents Created?Things to look out for:The title should be the first line of the document, with no blank lines or images above it.The title should be styled as heading 1 in one section so that it links to the title page.NCX can’t have a missing, incomplete, unreadable, duplicative, or inaccurate Table of Contents.Your NCX should contain links to your content, not the entire text or large passages of text.Ebook - Page References Fonts and pages resize on e-readers, so page numbers are variable, and EPUB files create a table of contents automatically.Explicit ContentExplicit or overly suggestive content within the metadata (title, author, description) or marketing image of publications is not accepted. Depictions of extreme sexual acts, including forced sexual acts, sexual violence, incest, and bestiality, are not accepted nor do they accept explicit images with no educational or artistic value, nor explicit content involving children or participants below the age of consent—nor do they permit pseudo depictions of these acts, or content linking to websites with explicit content.Improper CapitalizationThe first letter of all words in the title, subtitle, and author name should be capitalized, except for the following words: a, an, and, for, from, of, or, the, and to.

If this book is part of a series, provide the series or volume number in the metadata and resubmit.ISBN MismatchThe ISBN in the interior or cover does not match the metadata.
