Book Schema Validation API

Book schema markup enables Google to display book rich results — allowing users to find a book across multiple retailers and formats (print, ebook, audiobook) directly in search. Valid Book structured data helps Google associate your page with a specific work and can trigger book-specific knowledge panels. The Audiobook sub-type extends Book for audio format editions.
