    • EPUB file is incomplete (Example: missing chapters)
    • Bad transcoding in the EPUB file. This is commonly caused from improperly encoding the text in UTF-8 or UTF-16 format. (Example: Äù ‚Äô ‚Äú ‚Ä¢ displaying instead of quotes, apostrophes, or bullets)

The first letter of all words in the title and subtitle should be capitalized, except for the following words: a, an, and, for, from, of, or, the, to.

    Ex: <, >, etc.
  • Do not use font sizes in the description
    Ex: <font face=”Helvetica” size=”3”>

Author Name:

  • Regardless of how they appear on the cover, author names must be correctly spelled and capitalized in metadata.  Do not enter author names in all capital letters.

  • First name should appear before the last name
    Ex: Bob Young, not Young, Bob
  • Author names must also be correctly capitalized in the metadata.
  • Do not enter author names in all capitals.
  • All main authors who are equally credited on the cover art and ebook must be entered individually. If a book has more than one author, do not omit an author or combine both authors in one field. This is called a “compound artist.” Compound artists prevent retail channels from identifying individual authors. Customers then can’t find the book when searching for an individual author.
