Book Metadata/Book info

Metadata details for a book include basic bibliographic information. Some book settings are specific to Google Books or Google Play. You can edit this information in the book catalog in your Partner Center account. If you wish to make edits for multiple books at once, you can use a spreadsheet.

The ISBN (or other identifier), genre, and title are required, but you should complete as many fields as possible. More data helps readers discover your books.

Partners who use ONIX: Any changes you make in the Partner Center should also be made in your ONIX feed, because the next time you send an ONIX feed, the information you provided via ONIX will overwrite your existing settings.
ISBN or other identifier The ISBN for this edition of the book. If your book doesn't have an ISBN, it'll be assigned a unique identifier by our system. You can't edit this field. If you need to change the identifier, go to the Summary tab and deactivate this book, then add a new book with the correct identifier.
Book format/Format The type of book for this specific ISBN or other identifier. For a new book, this field is prefilled with Ebook by default.
Title The title of the book.
Subtitle The subtitle of the book.
Description A description of the book, such as might be found in back cover copy.

The primary language of the book.

If you use an old Partner Center, use a 3-letter ISO 639-2 code, like eng for English.

If you use a new Partner Center, select a list of languages or start typing a keyword to see matching languages.

Age groups/Minimum age & maximum age The age range of the intended audience for the book.
On sale date Leave this field blank if the book can be made available for sale on Google Play immediately. If the book is under embargo, enter a date in the future to prevent the book from becoming available for sale before that date. Use the format YYYY-MM-DD.

This page may be eligible for series-related promotional opportunities, like series bundles and notifications.

When a designated page for your series is created, the way Play displays your books will be optimized for the series experience. If any changes you made to series name and series number don't update on the Play Store after 48 hours, ⁠contact us.

Select one subject standard. We recommend Book Industry Subject and Category (BISAC) codes because genres in the Play Store are based on BISAC. You can choose between these standards:

  • BISAC [2018 Edition] (North America)
  • BIC (UK and Australia)
  • WGSneu (Germany)
  • C code (Japan)
  • CLIL (France)
  • UDC (Russia)
  • GKSS (South Korea)
  • Manga (Japan and South Korea)

After you select a subject standard, you can assign genres to a book. To choose the genre of a book, enter a keyword to find genres that match. We recommend you choose a maximum of 3 genres per book. The first genre should be the most relevant to the book. All 3 genres must be from the same standard.

Contributors Contributors typically include (but are not limited to) the author, editor, or illustrator. You can add as many contributors as needed.
Biographical note/Description for contributors Information about the contributors.
