eBooks do not typically include back covers. The purpose of the back cover is to entice readers to purchase your book. With eBooks, the readers will not see the back cover until after they have already purchased it. Because of this, BookBaby will not automatically include your back cover in the conversion process. We recommend including the information from your book cover in your metadata so that your readers can see the the information prior to purchasing your eBook.
However, if you do desire to include one, you should include it in your manuscript prior to uploading it to your project center. Requesting a back cover after your files have already been converted to eBook may result in a text edit fee.
