Publish your book with Pages

1. Open the Pages document you want to publish as a book.
2. Do the following for the device you're using:
   • On Mac, choose File > Publish to Apple Books.
   • On iPhone, tap the More button , tap Export, then tap Publish to Apple Books.
   • On iPad, depending on what you see in the toolbar, tap the document name or tap the More button in the toolbar, tap Export, then tap Publish to Apple Books.
   • Online at iCloud.com, click the More button, then choose Publish to Apple Books.
3. Tap or click Continue, then sign in to iTunes Connect. If you've never signed in, create an account:
   • On Mac, click Create iTunes Connect Account. 
   • On an iPad or iPhone, or online on iCloud.com, sign up for an account.
4. Tap or click Continue. After this step, any changes you make to the Pages document won't appear in the published book. If you need to stop the publishing flow and make changes to the Pages document, just close the publishing window.

Next, choose the seller of the book and add the version information:

1. If your iTunes Connect account has more than one seller, tap or click the Seller pop-up menu, then choose a seller. All those listed in your iTunes Connect account will appear in the menu – choose any as the seller.
2. If you're publishing this book for the first time, select "This is a new book". You can also update a previously submitted book.
3. Click Continue.

After you've provided the seller and version information, you can choose a layout type for your book and enter other information about your book. Not every field is required, but many of these fields can help readers find your book in the Book Store. Here are some tips about the options on this page:

• If your Pages document is a word-processing document, choose a layout for your book. Choose Reflowable for a book that has mostly text, such as a novel. In a Reflowable layout, content reflows to accommodate different devices and orientations, and readers can adjust the font size. Choose Fixed for image-heavy or multi-column documents.
• To display two-page spreads in a fixed layout book, choose Book Spread > Two Pages.
• To add a subtitle or series name, in the Title section click the Add button . If you're not using a subtitle or series name, click the Remove button  to remove the field.
• To add additional roles, such as Editor, Illustrated by, Narrated by and more, tap or click the Add button  in the Author section, click the Author pop-up menu, choose a role, then enter a name.
• To help readers find your book, choose a subject category that best describes the content of your book. You can add additional categories, but Apple Books uses the first three categories you chose.
• If your book is for minors, set an interest age. Or tap or click the Interest Age pop-up menu and choose one of the school year options:
  • To set a minimum school year, set the first option only.
  • To set a maximum school year, set the second option only.
  • To set a school year range, set both options.
  • To set a specific school year, set both options to the same school year.
• If your book is only appropriate for adults or is extremely violent, click the Contains Explicit Content pop-up menu and choose Yes.
• To set up a pre-order option, tap or click the Pre-Order pop-up menu, then choose Yes. To upload your book now, click the Upload Book pop-up menu and choose Yes. After you've uploaded your book, you can add pricing, region and pre-order details in iTunes Connect.*

When you're ready, click Continue. If errors appear, enter the required information, then click Continue again.

* Your book won't be available in the Book Store until you've added this information in iTunes Connect after uploading your book.

After you've entered your book information and clicked Continue, you can preview the book and sample EPUB files. The preview EPUB files will open in the Books app.

If you're publishing from Pages online on iCloud.com, the files will be downloaded to the default download location on your computer. 

When you’re satisfied with your sample, click Upload.

After your book has been successfully uploaded to Apple Books, click Go to iTunes Connect. In iTunes Connect, add pricing and region information. If you've set up a pre-order option, add the pre-order details. 

As Apple Books reviews your submission, you’ll receive status updates by email. You can also check your book's review status at any time in the My Books section of your iTunes Connect account.
