Short answer: Apple Books distribution works best when the EPUB is standards-conformant, metadata is complete, navigation is dependable, and the book is tested before delivery through the chosen publishing route.
Start from EPUB conformance
Apple’s ecosystem builds on EPUB standards but also has platform-specific delivery and quality expectations. A standards-valid file is the starting point, not permission to skip previewing.
Treat accessibility as publication quality
Semantic headings, navigation, meaningful alternatives for images, and clear language information improve the book for readers using assistive technology and also improve structural quality generally.
Verify the distribution path
Authors may deliver directly through Apple’s tools or reach Apple Books through an aggregator. The practical workflow and account requirements depend on the chosen path.
Check current Apple guidance
Retailer documentation changes. Recheck current Apple Books publishing requirements at the time of submission rather than relying on a static checklist alone.
