Many authors and publishers using Kindle Direct Publishing (KDP) to publish eBooks also have a paperback published through KDP or another publishing house. Linking these formats to one another in the Amazon catalog provides the ideal browsing experience for customers, so make sure your eBook and paperback book details match exactly. These details include title, subtitle, author, contributor, volume, edition, and language.

During the publishing process, KDP will attempt to match title, author name, and other title information to counterparts in the Amazon catalog. If you have a paperback and eBook of the same title, these will automatically link if the information matches exactly. For information on timelines, see our Help page.
