Many authors and publishers using Kindle Direct Publishing (KDP) to publish eBooks also have a paperback published through KDP, CreateSpace, or another publishing house. Linking these formats to one another in the Amazon catalog provides the ideal browsing experience for customers, so you'll want to make sure your eBook and paperback edition titles and subtitles (if applicable) match exactly.

During the publishing process, KDP will attempt to match title, author name, and other title information to physical counterparts available in the Amazon catalog. If you have a paperback and eBook of the same title, these will automatically link if the title and author information match exactly.

For information on timelines, including details on new publications and updates to published books, see our Help page.

Contact us if your editions are still not linked and:

• Both editions (eBook and paperback) have had detail pages for 72 hours
• The book information (title, subtitle, series name, author name) matches

If you contact us, please provide the 10-digit ISBN number of the paperback and the ASIN of the eBook.
